Abstract

The scientific community believes there is a great chance that the next technological revolution is coming from the control of biological processes. Great changes are expected, from the way we produce food up to the way we fight diseases. The control of biological processes will allow us to produce synthetic meat as food, to produce biofuels extracting CO2 directly from the atmosphere, to produce whole synthetic organs for transplant and to fight diseases, like cancer, in more efficient ways. It is clear to our group that in order to obtain these results it is necessary to understand biology from its most basic unity: the cell. Only from understanding and controlling chemical reactions inside a cell, and more specifically from the DNA controlling, it will be possible to achieve these predictions and cause a revolution in the way we live nowadays. Bearing these thoughts in mind, the objective of this thesis was to develop an integrated photonic platform for study of cellular processes. We believe that photonic tools are the only tools that fulfill all the requeriments for studies of cellular processes because they are capable to follow processes in real time without any damage to the cells. The techniques integrated are: 1 or 2 photon excited fluorescence, second or third harmonic generation, optical tweezers, fluorescence lifetime imaging and fluorescence correlation spectroscopy. In this thesis we demonstraded how to assemble this integrated plataform and we showed its versatility with results from different areas of biology and quantum dots. (AU)
