To obtain the AgNp release rate the pure, NRL.Membranes and the NRL - AgNP delivery systems.Were individually immersed in a flask containing.20 mL of Mili-QTM water. Then 2 mL, of each.Solution were collected for UV - Vis spectroscopy.Experiments. The spectra of solutions containing.Immersed NRL - AgNP were acquired using the solution.Containing immersed pure NRL membrane as.Reference to subtract, any possible absorption bands.Arising from molecules released by the, NRL membraneAnd insure that only the plasmon absorption.Band of the AgNP was accounted for. After the UV -Vis spectrum was registered the aliquot, was returned.To the flask to avoid, alteration in the total volume of.Water. This procedure was repeated, several timesAlong 48 h.The zeta potential and the particle size distributions.(PSD) were measured on a Zeta-Sizer system (Malvern.Instruments). The zeta potential of the nanoparticles.Was measured from their electrophoretic.Mobility by employing a quartz capillary cell containing.A pair of palladium electrodes. This dispersion was.Injected into the capillary of the Zeta-Sizer system and.The zeta potential was measured ten times. The mean.Zeta potential values for three replicates were calculated.For the PSD the data, were collected at a fixed.
