Abstract
Living tissue cells such as animal or plant tissue cell are encapsulated in an inorganic gel by mixing an organosilicon precursor with an aqueous acidic solution to form a gel forming solution and hydrolyze the organosilicon precursor, cooling the gel forming solution, forming a mixture of living tissue cells and Hank's balanced salt solution, adding a base solution to the gel forming solution to form a mixture, immediately thereafter adding the mixture containing living tissue cells to the mixture containing the gel forming solution, and pouring the resultant mixture into a container where an inorganic gel forms encapsulating the cells. The organosilicon precursor may be tetraethoxysilane, tetrabutoxysilane, tetramethoxysilane or tetrapropoxysilane.
