Biological cell as waveguide

WebBiophotonics and Nanophotonics which are two major branches of Photonics, have been hot spots in the researches and applications in last two decades. The former is primarily focusing on the probing and controlling of biological targets (e.g. cell, DNA, bacteria and exosomes etc.) through photonics and optics. The latter is dedicated to the interaction … WebZero mode waveguides (ZMWs), subwavelength optical nanostructures with dimensions ranging from 50 to 200nm, have been used to study systems involving ligand-receptor interactions. We show that under proper conditions, lipid membranes will invaginate into the nanostructures, which confine optical excitation to subattoliter volumes. Fluorescence …
