Abstract :
We study the feasibility of a diffraction-based cell monitoring system that can be applied to sensing cell viability on an in vitro assay. The system captures angular shifts in the light profile diffracted by periodic blazed grating substrate on the cell status changes. The preliminary results simulated with a simple cell viability model are presented.
