Biohybrid silicon-organic materials architecture obtained using various structure-affecting agents

The article describes the immobilization of yeast cells Ogataea polymorpha VKM Y-2559 into organosilicon matrices based on tetraethoxysilane and dimethyldiethoxysilane using polyethylene glycol, polyvinyl alcohol and chitosan as structure-affecting agents. The influence of the structure-affecting agent on the time of formation of the sol-gel capsule around the cells and on the morphology of the hybrid material was determined. The formation of organosilicon material was confirmed using IR spectroscopy. Using the method of energy-dispersive X-ray spectroscopy, it was proven for the first time that the structure-affecting agent is not incorporated into the structure of the organosilicon shell.
