Advances in antimicrobial polymeric iodophors

2015, Medecine et Maladies InfectieusesCitation Excerpt :This phenomenon could be related to the ratio of free iodine/iodide ion (I2/I−). High concentrations in I− (the case of highly concentrated solutions) are correlated with low concentrations of non complex-bound and, therefore, active I2; and the I2 concentration increases with dilution [27–30] explaining the fact that povidone iodine should be used diluted. The presence of other agents, including detergent types, may also intervene in the weak activity observed at high concentration [31].
The resistance of polyvinylpyrrolidone-Iodine-poly(ε-caprolactone) blends to adherence of Escherichia coli
2005, BiomaterialsCitation Excerpt :ratio of PCL will facilitate the penetration of aqueous medium into the film and offer a greater surface area for drug diffusion through the fluid filled channel. In addition the known antimicrobial properties of PVP-I [30], this agent has been reported to possess microbial anti-adherence properties, which have been reported to be potentially useful for the prophylaxis of infection. For example, it has been reported that following treatment of either microorganisms (E. coli, S. epidermidis, C. albicans) or human buccal epithelial cells in vitro with PVP-I, there was a reduction in the subsequent microorganism-epithelial cell adherence interaction [16].
