Abstract
Methods, apparatus and substrates for the detection of reactions between biomolecules or cells and a second compound are disclosed. The invention detects interactions between ligands and receptors by utilizing detecting the diffusion of a species proximate a sensing area. Absorbance detection and diffraction sensors are utilized to monitor the rate of diffusion from the sensing area.
