Controlling the Material Properties and Biological Activity of Lipase within Sol−Gel Derived Bioglasses via Organosilane and Polymer Doping

The development of optical biosensors based on sol−gel entrapped proteins requires a detailed understanding of the evolution of the physicochemical properties of the material, their affects on protein function, and how these factors can be tailored by processing conditions. In this study, the polymer additives poly(vinyl alcohol) (PVA) and poly(ethylene glycol) (PEG) were dispersed into sol−gel processed materials derived from tetraethyl …
