A Simple Synthesis of Polymer Coated Gold and Silver Nanoparticles in Water for Potential Use in Biomedical Applications

Rahme K., Minassian G., Ghanem E., Sarkis M., Nakhl M., El Hage R., Souaid E., Holmes J.D., Notre Dame University (Louaize), LB

Herein we describe a simple method for the synthesis of highly stable gold (Au) and silver (Ag) nanoparticles (NPs) in water. Ag and Au NPs of different surface charges (positively charged, negatively charged, or nearly [...]

Positively charged Ag-dendron conjugates: Stability enhanced AgNPs for biomedical applications

Cho T.J., Liu J., Hackley V.A., National Institute of Standards and Technology, US

We developed positively charged silver nanoparticles ([Ag-Ds]+), nominally 20 nm in diameter, using dendron chemistry combined with reduction of silver nitrate in the presence of sodium borohydride. The conjugate was developed within the context of [...]

Peptide Functionalized Gold and Silver Nanoparticles Inhibit Respiratory Syncytial Virus (RSV) In Vitro

Baganizi D.R., Bawage S., Singh A., Singh S.R., Tiwari P., Dennis V.A., Singh A., Singh S.R., Alabama State University, US

Human respiratory syncytial virus (RSV) is a major cause of severe upper and lower respiratory tract infections in infants, and in high-risk adults. Currently, there is no vaccine and the available therapeutic agents have limited [...]

Synthesis of conductive elastic film and conductive fabric based on crosslinked carboxymethyl starch-AgNPs composite

El-Sheikh M.A., National Research Centre, Egypt, EG

The current work is developing a novel, facile and eco-friendly method for synthesis of highly concentrated silver nanoparticles (AgNPs) using AgNO3 as a precursor, the eco-friendly carboxymethyl starch (CMS) polymer as both reducing and stabilizing [...]

Co-Culturing Dorsal Root Ganglion Neurons with Schwann Cells Protects Them Against the Cytotoxic Effects of Silver Nanoparticles

Gao W., Leung S.W., Bhushan A., Lai J.C.K., Idaho State University College of Pharmacy, US

Because of their presumed inertness, silver nanoparticles are increasing employed in many consumer products. Nonetheless, their environmental and health hazard impact are not understood. Our previous studies led us to develop a co-culture model consisting [...]

Fast and Facile Synthesis of Stable and Biocompatible Silver nanoparticles Stabilized by Polyethylene Glycol

Jain S., Singh S., Pillai S., Alabama State University, US

Silver nanoparticles show enhanced properties, when supported onto a substrate and incorporated into organic or inorganic matrix. Their remarkable properties are shape and size dependent. Ethylene glycol and its polymers are environment friendly or environmentally [...]

Effect of Porosity on Specific Resistance of Inkjet-Printed Silver Nanoparticles during Laser Sintering

Moon S.J., Moon Y.J., Kang H., Kang K., Kang H., Kang K., Lee S-H., Hwang J.Y., Moon S.J., Moon Y.J., Korea Institue of Industrial Technology, KR

In nano-metal sintering, the electrical resistivity of nano-metals is related to their structure. Electrical resistivity is affected by grain size and density. Larger grains and denser films yield lower electrical resistivity. This work investigated the [...]

Combating Dental Caries Via Restorative Materials Containing Antibacterial and Remineralizing Nanoparticles

Melo M.A.S., Cheng L., Zhang K., Weir M.D., Chow L.C., Antonucci J.M., Lin N.J., Lin-Gibson S., Lin-Gibson S., Xu H.H.K., University of Maryland Dental School, US

Dental caries is a wide spread public health problem, despite much effort in health promotion. Caries at the margins of restorations has been the main reason for failure. The development of direct-filling dental materials with [...]

Use of Single Particle Inductively Coupled Plasma Mass Spectrometry to Characterize a New Silver Nanoparticle Reference Material

Murphy K.E., Liu J., Guthrie W.F., Gorham J.M., Bonevich J.E., Allen A.J., Winchester M.R., Hackley V.A., MacCuspie R.I., National Institute of Standards and Technology, US

In this study we use a conventional inductively coupled plasma mass spectrometer operated in single particle mode (spICP-MS) to simultaneously characterize the size distribution and dissolved silver fraction of a new candidate silver nanoparticle reference [...]

Fast and Facile Synthesis of Stable and Biocompatible Silver nanoparticles Stabilized by Polyethylene Glycol

Jain S., Singh S., Pillai S., Alabama State University, US

Silver nanoparticles show enhanced properties, when supported onto a substrate and incorporated into organic or inorganic matrix. Their remarkable properties are shape and size dependent. Ethylene glycol and its polymers are environment friendly or environmentally [...]
