POROUS PHOTONIC CRYSTAL WITH LIGHT SCATTERING DOMAINS AND METHODS OF SYNTHESIS AND USE THEREOF

摘要

A method of sensing the presence, quantity and morphology of a target analyte that includes providing a porous substrate having a first optical signal, exposing the porous substrate to an environment suspected of containing the target analyte, and monitoring changes in the first optical signal over time. A cell-based biological and chemical sensor for detecting the presence, quantity, status and morphology of a cell and products of the cell that includes a porous substrate having a pore size, porosity gradient and a chemically functionalized surface to specifically target a cell type, wherein the porous substrate includes a first optical signal prior to exposure to the cell type, and a signal detector.
