Abstract

The interaction between light and biological matter can be exploited as a useful tool in various fields of science and technology. Indeed the optical behavior of living cells can permit to use them as micro-lenses for imaging, as photonic micro-resonators or waveguides, and also as advanced probes in holographic optical tweezers for manipulating the matter at nanoscale, and even bio-probes of localized fluorescence at sub-wavelength scale have been demonstrated. Here, we present an overview of these new insights about biological lenses. Theoretical modelling of the lensing effect of living cells will be discussed in details in case of Red Blood Cells. Digital holography in microscopy configuration is the tool that allow the experimental verification of this modelling thanks to the numerical refocusing capability. Applications of such new paradigm range from anemia diagnostics to bio-lithography.
