Synthesis of Bitten Gold Nanoparticles with Single‐Particle Chiroptical Responses (Small 26/2023)

Green Synthesis of Gold Nanoparticles

Nanotechnology has emerged as the interdisciplinary science conjugating the basic concept of engineering with the application of biology, chemistry, physics and medical science1. Research in the field of synthesis of nanoparticles has been growing dramatically over the last few decades due to their unusual and highly interesting properties with wide potential applications like antifungal activi...

Curcumin coated gold nanoparticles: synthesis, characterization, cytotoxicity, antioxidant activity and its comparison with citrate coated gold nanoparticles

Objective(s): Biological applications of gold nanoparticles have limitations because of the toxic chemicals used in their synthesis. Curcumin can be used as reducing as well as capping agent in synthesis of GNPs to eliminate the cytotoxicity. Conjugation of curcumin to gold also helps in increasing its solubility and bioavailability. Materials and Methods: Here we report synthesis of gold nanop...

Synthesis of gold nanoparticles inside polyelectrolyte brushes

In this work we report on the synthesis and characterization of Au nanoparticles grown in the inner environment of cationic polyelectrolyte brushes. The nanocomposite synthesis relies on loading the macromolecular film with AuCl4 2 precursor ions followed by their in situ reduction to Au nanoparticles. We observed that the nanoparticles are uniform in size and are fully stabilized by the surrou...

Synthesis and Characterization of Gold Nanoparticles

Synthesis and Characterization of Gold ‎Nanoparticles using Plant Extract of ‎Terminalia arjuna with Antibacterial ‎Activity

   The use of plant extracts for nanoparticles synthesis are green, economical and cost effective approach.  The present study reports the bio-synthesis of gold nanoparticles (Au NPs) using leaf extract of Terminalia arjuna. After exposing the gold ions to aqueous solution of leaf extract, rapid reduction of gold ions into gold nanoparticles is observed within few minutes. The characterizat...
