Bioluminescence future

Bioluminescence still has many mysteries, which may yield many further insights into nature and science. In bioluminescence reactions, a luciferin generates the energy for light emission when oxidized. For that reason, luciferin is the most important element in bioluminescence it can be considered as the heart of the bioluminescence reaction. Because of its importance, the author believes that the determination and identification of the structure of luciferins should be considered as one of the top targets in future research. The functional group of a photoprotein corresponds to a luciferin in its function, thus it is as important as a luciferin. Many luciferins and the functional groups of photoproteins remain to be determined, and at least two of them... 

For bioluminescent symbiotic fish and squid, expulsion of luminous bacteria into surrounding SW is a fundamental process that ensures horizontal transfer of the bacterial partner to future host generations. Considering the sophisticated coordination of various shutter mechanisms surrounding the internal LO of leiognathids, we believe the expulsion event to be a finely controlled discharge of symbiotic bacteria, rather than an uncontrolled phenomenon.

Bioluminescence resonant energy transfer is shown to offer a highly robust way to make use of bioluminescent reactions to detect substance of interest with unprecedented sensitivity. Two future directions involve improvement in the throughput capacity and the development of further miniaturized handheld systems. 

Parallel to the developments achieved in methodology and hardware, the conventional methods and some of the new approaches have been employed to study several types of photoinduced processes which are relevant mainly in biology and nanotechnology. In particular, important contributions have been made related to the topics of photodissociations, photostability, photodimerizations, photoisomerizations, proton/hydrogen transfer, photodecarboxylations, charge transport, bioexcimers, chemiluminescence and bioluminescence. In contrast to earlier studies in the field of computational photochemistry, recent works include in many cases analyses in solution or in the natural environment (protein or DNA) of the mechanisms found in the isolated chromophores. In addition, semi-classical non-adiabatic molecular dynamics simulations have been performed in some studies to obtain dynamical attributes of the photoreactions. These latter calculations are however still not able to provide quantitative accuracy, since either the level of theory is too low or too few trajectories are generated. Within this context, theory and hardware developments aimed to decrease the time for accurate calculations of the PESs will certainly guide future achievements in the field of photodynamics. 

At the University of Tennessee s Center for Environmental Biotechnology, researchers are developing wireless biosensors that can be used to monitor microbial contamination and radiation exposure in future manned space missions. The researchers are using bioluminescent biosensor organisms built directly onto wireless integrated circuits. They call them Bioluminescent Bioreporter Integrated Circuits (BBIC). Bioluminescent... 

This review summarises and discusses the advances of computational photochemistry in 2012 and 2013 in both methodology and applications fields. The methodological developments of models and tools used to study and simulate non-adiabatic processes are highlighted. These developments can be summarised as assessment studies, new methods to locate conical intersections, tools for representation, interpretation and visualisation, new computational approaches and studies introducing simpler models to rationalise the quantum dynamics near and in the conical intersection. The applied works on the topics of photodissociation, photostability, photoisomerisations, proton/charge transfer, chemiluminescence and bioluminescence are summarised, and some illustrative examples of studies are analysed in more detail, particularly with reference to photostability and chemi/ bioluminescence. In addition, theoretical studies analysing solvent effects are also considered. We finish this review with conclusions and an outlook on the future.
