Silver nanoparticles (AgNPs) have been widely used in over 1400 commercial applications because of their great antimicrobial properties and are found in everyday items such as food packing, UV-protectants, makeup, clothing, and medical devices such as stents, gauze, and surgical tools. AgNPs can eliminate body odor in clothing, as well as reduce biofilm formation on implants, making them a versatile and effective solution for unwanted bacterial growth. There is also a significant interest in harnessing the X-ray attenuation properties of AgNPs for use as X-ray imaging agents or tags on medical devices. Consequently, there is a critical need for the development of not only safe AgNPs, with minimal or no Ag+ ion release, but also effective deposition and retention on their applied surfaces. In this presentation, we will discuss the design of AgNPs with a hybrid lipid-coating with controlled Ag+ ion release, as well as their deposition, retention, and antibacterial efficacy on surfaces for potential use as antimicrobial agents, X-ray tags, or conductive inks. We will discuss methods of deposition, adherence, and bactericidal activity of AgNP surfaces using UV-Vis spectroscopy and scanning electron microscopy after exposure to conditions that damage or remove of AgNPs from surfaces.
