Journal ArticleDOI
Ion Release Kinetics and Particle Persistence in Aqueous Nano-Silver Colloids
Jingyu Liu,Robert H. Hurt +1 more
TL;DR: An empirical kinetic law is proposed that reproduces the observed effects of dissolution time, pH, humic/fulvic acid content, and temperature observed here in the low range of nanosilver concentration most relevant for the environment.
Journal ArticleDOI
Controlled release of biologically active silver from nanosilver surfaces
TL;DR: In this paper, the authors apply elements of the drug delivery paradigm to nanosilver dissolution and present a systematic study of chemical concepts for controlled release, where the particle contains a concentrated inventory of an active species, the ion, which is transported to and released near biological target sites.
Journal ArticleDOI
Chemical transformations of nanosilver in biological environments.
TL;DR: It is shown that silver nanoparticles undergo a rich set of biochemical transformations, including accelerated oxidative dissolution in gastric acid, thiol binding and exchange, photoreduction of thiol- or protein-bound silver to secondary zerovalent Ag-NPs, and rapid reactions between silver surfaces and reduced selenium species.
Journal ArticleDOI
Kinetics and mechanisms of nanosilver oxysulfidation.
TL;DR: It is demonstrated that silver nanoparticles react with dissolved sulfide species (H(2)S, HS(-)) under relevant but controlled laboratory conditions to produce silver sulfide nanostructures similar to those observed in the field.
Journal ArticleDOI
Aerosol synthesis of cargo-filled graphene nanosacks.
Yantao Chen,Fei Guo,Ashish Jachak,Sang-Pil Kim,Dibakar Datta,Jingyu Liu,Indrek Külaots,Charles A. Vaslet,Hee Dong Jang,Jiaxing Huang,Agnes B. Kane,Vivek B. Shenoy,Robert H. Hurt +12 more
TL;DR: Water microdroplets containing graphene oxide and a second solute are shown to spontaneously segregate into sack-cargo nanostructures upon drying, promising for many applications where nanoscale materials should be isolated from the environment or biological tissue.
