Abstract

Here AgNPs were synthesized from leaf extracts of Cymbopogon citratus (lemon grass), along with their antibacterial and antidiabetic properties. The reduction rate of AgNPs at 215, 235, and 302 nm was faster, and UV–vis tests were used to verify colloidal manufacture of AgNPs. Nevertheless, TEM revealed that the particles used in the study were spherical nanoparticles with a 40 nm size range. AgNPs may surround amines based on observations of a peak at 1531 cm−1, because ─NH2 symmetric stretching and N─O bonds are common in nitro compounds. Compared to leaf extract, AgNPs exhibit C─X stretching vibrations at 663 cm−1, indicating that alkyl halide groups are present. Experimental data revealed that the indexed peak has a lattice parameter of 4.0957. Besides gram-positive bacteria, AgNPs are also capable of killing multi-drug-resistant bacteria as well. As concentrations of AgNPs were increased, the percentage of inhibition activity increased, indicating that they are effective at controlling diabetes.
