DNA was immobilized within alginate matrix using an external or an internal calcium source, and then membrane coated with chitosan or poly-L-lysine. Membrane thickness increased with decreasing polymer molecular weight and increasing degree of deacetylation (chitosan). Beads were exposed to a 31,000
