Protein adsorption and desorption studies. Biocompatibility.


Protein adsorption and desorption applications can be divided into two categories: those in which it is desired to minimize adsorption, and those in which it is desired to maximize it. The grating coupler sensor, by virtue of the unprecedented precision and time resolution with which it is possible to measure adsorption and desorption kinetics, has become an indispensable tool for studies aimed at elucidating the fundamental mechanisms underlying these processes at the molecular level.
