Organised by Professor Peter J Sadler FRS, Professor Akhil R Chakravarty and Dr Nicola J Farrer
Photoactivation of metal complexes presents relatively unexplored potential for the discovery of new chemistry with applications in biotechnology and medicine. This meeting will bring together experts in theory and computation, photophysics, photochemistry, photobiology, and pharmacology to accelerate progress in this highly interdisciplinary and emerging field, and especially to assess the challenges of introducing metal-based photochemotherapy into the clinic.
Biographies of the organisers and speakers are available below and you can also download the programme. Recorded audio of the presentations will be available on this page after the event and the papers will be published in a future issue of Philosophical Transactions A.

Professor Roberto Etchenique, University of Buenos Aires
I am a Professor of Analytical Chemistry at Universidad de Buenos Aires, Argentina, where I work on chemical tools that can be applied to biological research. Since 2003 we have developed a new family of caged compounds based on the photochemistry of Ruthenium-polipyridine chemistry. The heterolytic cleavage obtained through irradiation onto the Ruthenium complexes allow us to deliver entire molecules without any side reactions. Moreover, the band structure of ruthenium-bipyridine complex permits the utilization of mild visible light instead of the more deletereous UV light needed for other caged compounds.In the last years (2010-2011) we began to extend this approach in new directions. We have worked on photoactivated surfaces that promote cell adhesion and in new antenna-fluorophore ligands to devise phototriggers with high absorption cross-section at long wavelengths capable to deliver chemicals in a biologically friendly environment.
