Silver Nanoparticles Agglomerate Intracellularly Depending on the Stabilizing Agent: Implications for Nanomedicine Efficacy

Synthesis of silver nanoparticles using a biosurfactant produced in low-cost medium as stabilizing agent

Silver Nanoparticles as a Smart Antimicrobial Agent

In modern medicine the resistance to conventional antibiotics is becoming a serious concern due to high instances of mortality. Several metallic nanoparticles are suggested as promising anti-microbial agents against multidrug-resistant bacteria and some viruses. Among the nanoparticles mentioned, we review the recent finding which demonstrate the impact of silver nanoparticles on antimicrobial ...

Short-term changes in intracellular ROS localisation after the silver nanoparticles exposure depending on particle size

Silver nanoparticles (AgNPs) induce the production of reactive oxygen species (ROS) and apoptosis. These effects are enhanced by smaller particles. Using live-cell imaging, we show that AgNPs induced ROS production rapidly in a size-dependent manner after exposure of cells to 70-nm and 1-nm AgNPs (AgNPs-70, AgNPs-1), but not AgNO3. Exposure of cells to 5 μg/mL each of AgNPs-70, AgNPs-1 or AgNO3...

Silver nanoparticles: influence of stabilizing agent and diameter on antifungal activity against Candida albicans and Candida glabrata biofilms.

AIM   The purpose of this work was to evaluate the size-dependent antifungal activity of different silver nanoparticles (SN) colloidal suspensions against Candida albicans and Candida glabrata mature biofilms. METHODS AND RESULTS   The research presented herein used SN of three different average sizes (5, 10 and 60 nm), which were synthesized by the reduction of silver nitrate through sodium ...

Silver nanoparticles as an antibacterial agent for endodontic infections

Materials and method Silver nanoparticles have gained more attention owing to their broad spectrum of antibacterial activity and low cost of manufacturing. In the present study, starch coated silver nanoparticle were synthesized and characterized by SEM/ EDX and UV/Vis spectroscopy. Starch coated nanosilver was tested for their antibacterial activity against various microorganisms that are comm...
