Synthesis of biofunctionalized AgNPs using medicinally important Sida cordifolia leaf extract for enhanced antioxidant and anticancer activities

Green synthesis of silver nanoparticles using aqueous leaf extract of Premna integrifolia (L.) rich in polyphenols and evaluation of their antioxidant, antibacterial and cytotoxic activity

“…Changes in the intensity and small shifts were observed in the spectra of the extract and the nanoparticles. This may be due to co-ordination of phytochemicals with metal surface [25]. Important linkages such as C = O, -C-OC-, N-H, -C = C-, -C = C-H and C-H are formed during the process of nanoparticle synthesis [24].…”

Stability of Synthesized Silver Nanoparticles in Citrate and Mixed Gelatin/Citrate Solution

“…There are factors that influence the stability of AgNPs, such as the concentration of the precursor, pH, temperature, order of mixing of reactants and stabilizers [6,7]. For example, different kinds of stabilizers/capping agents, such as surfactants, polymers and reducing agents, are used for the surface modification of AgNPs during their synthesis to control the size, morphology, stability, and physicochemical properties of AgNPs [8][9][10].…”

“…Silver nanoparticles are typically prepared through the reduction of a silver precursor using chemical or physical means [4,9]. Chemical reduction of a silver nitrate salt in an aqueous media by a reducing agent in the presence of a surfactant is a facile synthetic method.…”

The Influence of Silver Nanoparticles Synthesis on Their Properties

“…Therefore there is a need to replace physical and chemical techniques of AgNPs preparation by green alternatives, which are cost-effective, safe, environment-friendly and easily scaled up for large syntheses of NPs. The use of biomolecules like proteins and lipids present on NPs surfaces has a great potential in AgNPs synthesis due to their non-toxic nature and also gentle synthetic procedures [9,10]. Therefore there is a growing concern to apply biomimetic which use plants, bacteria, fungi, yeast, actinomycetes and algae for synthesis of nanostructures of biocompatible metals and semicon-ductors [5].…”
