Ratiometric Phosphorescent Silver Sensor: Detection and Quantification of Free Silver Ions within Silver Nanoparticles.

Silver nanoparticles (AgNPs) have well-known antibacterial properties that have stimulated their widespread production and usage, which nonetheless concomitantly raises concerns regarding their release into the environment. Understanding the toxicity of AgNPs to biological systems, the environment, and the role that each silver species (Ag ions vs AgNPs) plays in that toxicity has received significant attention. One of the critical objectives of this research is the development of a reliable method that can sense and differentiate free silver ions from AgNPs and is able to characterize silver ions leaching from nanosilver.

Shining Light on Chitosan: A Review on the Usage of Chitosan for Photonics and Nanomaterials Research.

Chitosan (CS) is a natural polymer derived from chitin that has found its usage both in research and commercial applications due to its unique solubility and chemical and biological attributes. The biocompatibility and biodegradability of CS have helped researchers identify its utility in the delivery of therapeutic agents, tissue engineering, wound healing, and more. Industrial applications include cosmetic and personal care products, wastewater treatment, and corrosion protection, to name a few.

A Phosphorescent Trinuclear Gold(I) Pyrazolate Chemosensor for Silver Ion Detection and Remediation in Aqueous Media.

We report a phosphorescent chemosensor based on a trinuclear Au(I) pyrazolate complex or [Au(3-CH,5-COOH)Pz] (aka AuPz) stabilized in aqueous chitosan (CS) polymer media. AuPz is synthesized in situ within aqueous CS media at pH ∼ 6.5 and room temperature (RT).
