Fig. 3From: Green immobilization and efficient proliferation of Escherichia coli cells in polyvinyl alcohol hydrogel membranes by unidirectional nanopore dehydrationAppearance and 60-day water stability of ECI-PVAHMs loaded with bacteria in the wet state. a, b The wet bacteria-loaded and non-bacteria-loaded PVAHMs, respectively; c The dissolution rate experiment. The purified water immersed in the membrane was changed every 2 days, and the weight on the first day and the wet weight on the last day were used to calculate the residual amount or dissolution rate of the hydrogel filmBack to article page
