Surfactant-modified silver nanoparticles

Silver nanoparticles were incorporated into PIA-based films which were obtained by casting from a CF solution. To accelerate the release of silver, composites were prepared by adding pure or surfactant-modified cellulose nanoctystals. The TEM images showed that silver and cellulose particles were distributed homogenously, results which were confirmed by the improvement of barrier properties to o g gen and water. However, the migration from the films and the release of silver increased with the presence of cellulose, especially when cellulose was modified with a surfactant. A potential interaction between the surfactant and PLA that resulted in degradation of the polymeric matrix might be the cause of such an effect. This report did not include the antimicrobial activity analysis of the prepared films. ... 

Other chemical reactions can be performed in the presence of carbohydrate modified siloxane surfactants. For example, a glucose substituted cyclosiloxane has been successfully used to stabilize silver nanoparticles (Figure 2) [102].
