| Description |
Green synthesis of nanoparticles is one of the crucial requirements in today’s climate change scenario all over the
world. In view of this, leaf extract (LE) of Bauhinia variegata L. possessing strong antidiabetic and antibacterial properties
has been used to synthesise silver nanoparticles (SNP) in a controlled manner. Various-sized SNP (20–120 nm) were
synthesised by varying incubation temperature, silver nitrate and LE concentrations. The rate of SNP synthesis and their size
increased with increase in AgNO3 concentration up to 4 mM. With increase in LE concentration, size and aggregation of SNP
was increased. The size and aggregation of SNP were also increased at temperatures above and below 408C. This has
suggested that size and dispersion of SNP can be controlled by varying reaction components and conditions. Polarity-based
fractionation of B. variegata LE has suggested that only water-soluble fraction is responsible for SNP synthesis. Fourier
transform infrared spectroscopy analysis revealed the attachment of polyphenolic and carbohydrate moieties to SNP. The
synthesised SNPs were found stable in double distilled water, BSA and phosphate buffer (pH 7.4). On the contrary,
incubation of SNP with NaCl induced aggregation. This suggests the safe use of SNP for various in vivo applications.
