Chemists from Trinity College Dublin, in collaboration with RCSI, have devised a revolutionary new scanning technique that produces extremely high-res 3D images of bones -- without exposing patients to X-ray radiation.The chemists attach luminescent compounds to tiny gold structures to form biologically safe ‘nanoagents’ that are attracted to calcium-rich surfaces, which appear when bones crack – even at a micro level. These nanoagents target and highlight the cracks formed in bones, allowing researchers to produce a complete 3D image of the damaged regions.The technique will have major implications for the health sector as it can be used to diagnose bone strength and provide a detailed blueprint of the extent and precise positioning of any weakness or injury. Additionally, this knowledge should help prevent the need for bone implants in many cases, and act as an early-warning system for people at a high risk of degenerative bone diseases, such as osteoporosis.
The research, led by the Trinity team of Professor of Chemistry, Thorri Gunnlaugsson, and Postdoctoral Researcher, Esther Surender, has just been published in the leading journal Chem, a sister journal to Cell, which is published by CellPress. The article can be viewed here.
Professor Gunnlaugsson said: “This work is the outcome of many years of successful collaboration between chemists from Trinity and medical and engineering experts from RCSI. We have demonstrated that we can achieve a three-dimensional map of bone damage, showing the so-called microcracks, using non-invasive luminescence imaging. The nanoagent we have developed allows us to visualise the nature and the extent of the damage in a manner that wasn’t previously possible. This is a major step forward in our endeavour to develop targeted contrast agents for bone diagnostics for use in clinical applications.”
The work was funded by Science Foundation Ireland and by the Irish Research Council, and benefited from collaboration with scientists at RCSI (Royal College of Surgeons in Ireland), led by Professor of Anatomy, Clive Lee.Professor Lee said: “Everyday activity loads our bones and causes microcracks to develop. These are normally repaired by a remodelling process, but, when microcracks develop faster, they can exceed the repair rate and so accumulate and weaken our bones. This occurs in athletes and leads to stress fractures. In elderly people with osteoporosis, microcracks accumulate because repair is compromised and lead to fragility fractures, most commonly in the hip, wrist and spine. Current X ray techniques can tell us about the quantity of bone present but they do not give much information about bone quality.”He continued: “By using our new nanoagent to label microcracks and detecting them with magnetic resonance imaging (MRI), we hope to measure both bone quantity and quality and identify those at greatest risk of fracture and institute appropriate therapy. Diagnosing weak bones before they break should therefore reduce the need for operations and implants – prevention is better than cure.”In addition to the unprecedented resolution of this imaging technique, another major step forward lies in it not exposing X-rays to patients. X-rays emit radiation and have, in some cases, been associated with an increased risk of cancer. The red emitting gold-based nanoagents used in this alternative technique are biologically safe – gold has been used safely by medics in a variety of ways in the body for some time.
Dr Esther Surender, Postdoctoral Researcher at Trinity, said: “These nanoagents have great potential for clinical application. Firstly, by using gold nanoparticles, we were able to lower the overall concentration of the agent that would have to be administered within the body, which is ideal from a clinical perspective. Secondly, by using what is called ‘two-photon excitation’ we were able to image bone structure using long wavelength excitation, which is not harmful or damaging to biological tissues.”
She added: “These nanoagents are similar to the contrast agents that are currently being utilised for MRI within the clinic, and hence have the potential to provide a novel means of medical bone diagnosis in the future. Specifically, by replacing the Europium with its sister ion Gadolinium, we can tune into the MRI activity of these nanoagents for future use alongside X-ray and computed tomography (CT) scans.”
Professor Gunnlaugsson and his research team are based in the Trinity Biomedical Sciences Institute (TBSI), which recently celebrated its 5-Year anniversary. Professor Gunnlaugsson presented his research at a symposium to mark the occasion, along with many other world-leaders in chemistry, immunology, bioengineering and cancer biology -- read more here.

€150,000 FUNDING AWARDED TO AMBER RESEARCHER TO DEVELOP NEW THERMAL MANAGEMENT TECHNOLOGIES FOR THE AUTOMOTIVE INDUSTRY
Prof. Valeria Nicolosi is Ireland’s only five-time ERC awardee and has received research funding of €12 million in the past 5 years.
Wednesday 27th July 2016, Dublin: Prof Valeria Nicolosi from AMBER, the Science Foundation Ireland funded materials science centre, hosted in Trinity College Dublin, has been announced as a recipient of the European Research Council’s (ERC) Proof of Concept Grants, worth €150,000.This is a top-up for her ERC Starting Grant of €1.5m awarded in 2011 and brings her total research funding awarded in the past 5 years, to over €12 million. Prof. Valeria Nicolosi is Ireland’s only five-time ERC awardee. The award will be used to explore the commercial use of advanced nanomaterials to act as solutions for heat dissipation for the high-end automotive industry. Proof of Concept grants are awarded to ERC grant holders only as top-up funding to explore the commercial or innovation potential of the results of their ERC-funded research. Prof Nicolosi, Investigator with AMBER and Trinity’s School of Chemistry was awarded an ERC Starting Grant of €1.5M in 2011 for her work in processing and characterising nanomaterials for the development of novel energy storage devices. As a result of this Starting Grant, she began collaborating with a company in the automotive industry to explore the use of novel 2-dimensional nanomaterials to solve heat dissipation issues. Her technology was successful and the aim of this proposal is to determine the economic and technical feasibility of using readily scalable technologies for the development of inexpensive and high performance solutions to solve heat dissipation for a wide range of technologies. Prof. Valeria Nicolosi, Professor at the School of Chemistry, Trinity College Dublin and Principal Investigator at AMBER, said, “I am delighted to be awarded this 3rd ERC Proof of Concept Grant which will allow me to build on the success of my technology developed from my Starting Grant. What is exciting about this work is that in addition to the automotive industry, there are a huge range of industrial applications that can benefit from more efficient and lightweight thermal management systems such as advanced aircraft, injection moulding, pharmaceutical manufacturing and household appliances. This technology has the potential to become a feasible, easy and efficient solution for a range of manufacturing companies. This grant is allowing me to take the next step with the technology to really see it applied in industry”. Considerable industrial effort is currently focussing on finding alternative materials to act as thermal conductive elements and heat spreaders in an efficient and cost effective way. Manufacturers need these technologies to regulate the large amounts of unwanted heat caused by the normal functioning of electronic systems. It is estimated that the global market for thermal management products will grow from about $10.7 billion in 2015 to $14.7 billion by 20211. Prof Nicolosi’s technology will offer a cheap, scalable solution of using advanced 2D nanomaterials for enhanced heat transport. 2D nanomaterials improve heat transport due to their thermal conductivity properties and at the same time provide a lightweight solution. Moreover, the technology offers the advantage of being extremely versatile; 2D nanomaterial dispersions can be sprayed on their own directly onto surfaces or they can be mixed with different materials to obtain additional enhanced resistance to wear, abrasion and oxidation. This will allow manufacturers to improve the performance of existing systems, as well as improve the performance of new designs.
Prof. Michael Morris, Director of AMBER, commented on the announcement, saying, “The awarding of this Proof of Concept Grant to Prof. Nicolosi is an excellent acknowledgement of the research work she and her team are currently undergoing. She is at the forefront in 2D nanomaterials research and her work will bring economic and societal benefits to Ireland in developing more efficient ways to deal with energy consumption. During her time at Trinity, Prof. Nicolosi has received over €12 million in funding, including €6.8 million to date from the ERC, and now an additional €150,000 to further her research. She is an exceptional asset to the AMBER team and this funding also reaffirms how competitive Ireland is as a place for research.”
On July 1st 2016, the School of Chemistry received delegates to Trinity’s Biomedical Sciences Institute for the first ever Medicinal Chemistry Conference Ireland. This significant event brought together some of the most relevant researchers in this multi-disciplinary field and highlighted Ireland’s strong wealth of graduates in the area. The organising committee, which included representatives of 7 Ireland’s national universities, welcomed 120 participants for the one-day conference which comprised of plenary talks from international speakers across academia and industry.

Emeritus Professor John Kelly, from Trinity College Dublin’s School of Chemistry, has been recognised for his part in decades-long research that has helped shed light, quite literally, on the precise mechanism of DNA damage.
Professor Kelly is a recipient of the 2016 Rita and John Cornforth Award, along with his collaborators Professor Christine Cardin, University of Reading, and Dr Susan Quinn, University College Dublin. The award, which places an emphasis on the importance of collaboration in scientific research, is handed out annually by the Royal Society of Chemistry. Professor Kelly said:
“I am delighted that our collaboration has been recognised with this award. My interests have always involved exploring photochemical reactions, and to fully understand the processes occurring from the initial absorption of a photon to the formation of a permanent product."
"The roots of our work go back to the 1980s when we started an ambitious project with Dan Bradley and David McConnell to target the reactions that take place in DNA.”
The Dublin-Reading DNA Consortium use specially synthesised molecules to see how – and exactly where – they bind to DNA. The reactions usually involve short-lived chemical species (such as ‘free radicals’), which are damaging to DNA and cells inside the body. The reactions often last for mere picoseconds (a billion times faster than a millisecond). Due to these very narrowest windows of opportunity, specialist crystallography and laser technology techniques are required to provide the all-important series of snapshots that illuminate what is really taking place. Working in the world-leading Rutherford Appleton Laboratory has recently enabled the scientists to follow the vibrations of excited molecules in DNA crystals, so as to follow the transit of the electrons that lead to DNA damage. That most recent breakthrough also opens the door for studies looking at direct UV excitation of DNA in crystals, which should help us gain an understanding of the processes that cause DNA photo-damage. It should also help related research in the fields of cancer medicine and drug development, as visible light irradiation of the compound in cancer cells leads to their destruction (as has recently been demonstrated by the Trinity groups of Professor Thorri Gunnlaugsson and Clive Williams).

Congratulations to Prof. Kelly and all involved.
Major Clean Energy Breakthrough Made by School of Chemistry Researchers
New material will increase adoption of hydrogen as a fuel in energy efficient transportation
The development of a real alternative to fossil fuels is perhaps the greatest technological challenge faced by humanity at present. Now, researchers in the School of Chemistry and CRANN (the Nanoscience Institute based at Trinity College Dublin) have developed a material which enhances the splitting of water at a very low energy cost using earth abundant raw materials. This new material performs as well as the world’s most effective material for water splitting (which is the scarce and expensive ruthenium oxide) but is much less expensive. This is a significant breakthrough, as it means that an energy efficient production of pure hydrogen is now possible using renewable energy sources which will potentially accelerate adoption of hydrogen as a fuel in energy efficient transportation.Hydrogen has been described as the ultimate clean energy source, it’s seen as very attractive as it is a pollution free fuel and energy carrier which would satisfy much of the energy requirements of our society. Hydrogen is readily prepared by splitting water electrically into its component parts hydrogen and oxygen (a process called electrolysis). However, this process requires a significant energy input. The widespread uptake of hydrogen as a fuel has been hampered by the lack of low cost, earth abundant materials which can accomplish the splitting of water, with minimal energy input, in an economically efficient manner using renewable energy sources.The CRANN breakthrough recently published in the prestigious international journal ACS Catalysis, has shown that the ruthenium content can be decreased by as much as 90% and substituted with the earth abundant and inexpensive manganese oxide without diminishing the efficiency of the material to split water. Professor Mike Lyons, Principal Investigator at the School of Chemistry and CRANN : “We are very excited about this very significant breakthrough. The adoption of this material in industry will mean that electrochemical hydrogen generation using photo (electrolysis) is now far more economically viable and will hasten adoption of hydrogen as a fuel in energy efficient transportation. It should be noted that this discovery could only have been accomplished using the world class characterization facilities and opportunity for interdisciplinary collaboration available within the School of Chemistry and CRANN.”Mike Lyons, continued: “Our disruptive materials breakthrough is momentous as it means much more energetically efficient and more economical hydrogen energy. This means that the cost of producing hydrogen via water electrolysis will be significantly reduced, which will result in a more rapid uptake of hydrogen as an automotive fuel.”Professor Mike Lyons leads the Trinity Electrochemical Energy Conversion and Electrocatalysis Group in the School of Chemistry. He has published two books and more than 126 papers, and has a h-index of 33, which demonstrates the worldwide impact of his research. Working with Professor Mike Lyons on this project, was Professor Paula Colavita, PI in the School of Chemistry/ CRANN, and Michelle Browne, PhD student. Characterisation of the materials were carried out by Dr. Hugo Nolan, supervised by Professor Georg Duesberg, PI in the School of Chemistry and CRANN.
