Autonomous Nanosensor System for Monitoring and Quantifying Arsenic in Water

Salinas S., Mosquera N., Yate L., Coy E., Yamhure G., González E., Pontificia Universidad Javeriana, CO

In present work, we have developed a system for detection and quantification of arsenic in water, based on surface plasmon resonance. The sensor uses a gold self-assembled monolayers on Au(111) substrate. Studies that we have [...]

Applying Plasmon Resonant Coating to Commercial Liposomal Delivery Systems

Knights-Mitchell S.S., University of Arizona, US

Multiple drug-encapsulated liposomes have been successfully marketed as pharmaceuticals within the past two decades. Some of these liposomal drugs have been shown to selectively localize within tumors. However, one limitation is the inability to control [...]

Annealing effect on composition and functional properties of hybrid C-Au-Ag nanoparticles

Manshina A., Povolotskiy A., Povolotskaya A., Koshevoy I., Tunik S., St. Petersburg State University, RU

Here we present an approach to the synthesis of hybrid C-Au-Ag nanoparticles which were found to be 20–30 nm carbon nanospheres containing dispersed Au-Ag bimetallic nanoparticles (1–5 nm). It was found also that C-Au-Ag NPs [...]

Drug Delivery with Light-Activated Gold-Coated Liposomes

Orsinger G.V., Leung S.J., Knights S.S., Williams J.D., Romanowski M., University of Arizona, US

With the ultimate goal of delivering therapeutic compounds selectively to cancerous or diseased tissues and cells, we have presented liposome-based plasmon resonant nanocapsules. The described biocompatible composite delivery vehicle enables encapsulation and selective release of [...]

Optical Trapping of Gold-Coated Liposomes

Leung S.J., Romanowski M., University of Arizona, US

We recently introduced a nanocomposite material, plasmon resonant gold-coated liposomes, to address unmet needs in area of controlled delivery. Plasmon resonant nanocapsules are created via the deposition of gold onto the surface of 100 nm [...]

Spectrally-Selective Light-Induced Release from Gold-Coated Liposomes

Leung S.J., Romanowski M., University of Arizona, US

To address unmet medical needs in the area of controlled delivery, we recently presented liposome-supported plasmon resonant gold nanoshells. These composite structures are degradable into components of a size compatible with renal clearance, potentially enabling [...]
