摘要： The present invention provides among other things silver nanoparticles and methods of making the same. The nanoparticles may be sulfidated to decrease the silver leaching rate and sustain the biocidal properties. Such nanoparticles may be applied as a coating or additive to substrates such as metals, alloys, polymers, membranes, textiles, and other such materials, allowing for the substrates to exhibit antimicrobial properties.

摘要： The present invention provides among other things a silver nanoparticle-coated membrane that reduces biofouling. The membranes exhibit extended antimicrobial properties that prevents the buildup that causes biofouling, which in turn prolongs the life of the membranes. The membranes may be reverse osmosis membranes, microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, or any other membrane suitable for liquid processes.
