The orientation of silver molecules where the surface of a metal meets a liquid was explored in the Journal of Ramen Spectroscopy in February 2013. The article, written by J. P. Schulte, S. Grass, and L. Treuel was first published in October, 2012. With an interest relating to the design of nano-structured metallic surfaces and catalytic processes, the adsorption geometry of molecules was studied. Using Ramen Spectroscopy, observations were made in the context of two pH variations. Through the use of maleic acid and fumaric acid, clear differences were observed.

Researchers led by Jeffrey L . Zink at UCLA have developed a method for encapsulating antimicrobial nanoparticles inside of mesoporous silica particles in service of creating a solid routine for the targeted delivery of nanoparticles, specifically for antimicrobial and bactericidal applications .
Studies involving bactericides have recently been focused on aiding the delivery of this material to specific beneficial sites . The desired outcome opportunities include incorporating antimicrobial materials into bandages for wound treatment and into water purification membranes . The innovation was possible because the mesoporous silica shell protects antimicrobial nanoparticles from aggregation and fast dissolution .
Other advantages include wider compatibility in biological environments, inexpensive, safe synthesis, and the ability to be incorporated into a variety of fabrics and substrates . The process was patented by Zink in 2012 and published by the UCLA Office of Intellectual Property & Industry Sponsored Research .

Originally published in Physical Review B . in 2001, this article details how Excitation and propagation of surface plasmons in silver films structured with narrow straight grooves were visualized with unprecedented detail by way of near - field optical techniques .
Authors Thomas Huser, A. Bouhelier, H. Tamaru, et al., of the Bielefeld University demonstrated reflectivity, transmissivity, and scattering loss of the grooves, showing that their values are determined semiquantitatively, finding that the surface plasmon attenuation is dominated by material and surface/interface imperfections.
