“…The b-ZnO image (Figure 1b) exhibits smaller particle sizes than the c-ZnO (Figure 1a) which might be due to the presence of a capping agent derived from the plant extract. Aqueous extract of Desmodium triquetrum contains polyphenols that could act not only as reducing agents but also as capping agents [15]. Capping agents can prevent the over-growth of nanoparticles and agglomeration in the synthesis process [18].…”

“…In this study, we investigated chemically and biosynthesized ZnO using Desmodium triquetrum leaf extract and their application as a UV filter. Desmodium triquetrum extract has been studied as an effective reducing and capping agent to synthesize silver nanoparticles and their application as antibacterial, antibiofilm and anticancer [15]. However, using Desmodium triquetrum to synthesize zinc oxide nanoparticles and their application as potential UV filters has not been reported yet.…”

Plant-based synthesis of nanoparticles has been a great interest topic due to reducing the use of toxic materials and the presence of bioactive compounds. This study investigated the chemically synthesized and biosynthesized zinc oxide (ZnO) nanoparticles using Desmodium triquetrum leaf extract and their potential as UV filters. These ZnO were evaluated using FE-SEM, EDX, XRD, and FTIR. The in-vitro Sun Protector Factor (SPF) was determined using a spectrophotometer. SEM image revealed the flower shape morphology of biosynthesized ZnO and chemically synthesized ZnO with different particle sizes. The biosynthesized ZnO nanoparticles exhibited smaller particle sizes than chemically synthesized ZnO. XRD analysis demonstrated that the average crystallite sizes of biosynthesized and chemically synthesized ZnO were 10.34 nm and 15.08 nm, respectively. The biosynthesized ZnO showed an SPF value of 25.12, indicating stronger UV protection ability than chemically synthesized ZnO (SPF=9.72) at a concentration of 1 mg/mL. These results indicate that the biosynthesized ZnO nanoparticles could be a great candidate as a UV filter for further sunscreen formulations.

Green synthesis of metal nanoparticles using plant sources is one of the most environmentally sound, economically safer, and operationally simple approaches compared with their physiochemical methods. In this work, we have developed the biogenic synthesis of Ag nanoparticles using the aqueous peel extract of Punica granatum L. fruit, which mitigates the requirement for any hazardous reagents or toxic chemicals. The ultraviolet‐visible spectrum confirmed the formation of Ag@PPE NPs with an absorption peak at 420 nm. The X‐ray diffraction analysis confirms that the biosynthesized Ag@PPE NPs are crystalline, with a crystallite size of 9.23 nm. SEM and TEM images revealed the spherical morphology of Ag@PPE NPs, with particle sizes ranging from 2 to 20 nm. The biosynthesized Ag@PPE NPs were explored as antimicrobial agents against both Gram‐positive (CA‐MRSA) and Gram‐negative (Escherichia coli) bacteria as well as Candida albicans (ATCC 14053). The mean zone of inhibition against the CA‐MRSA group was 15.34 ± 2.5 mm, while it was 12.33 ± 1.5 mm against E. coli. In this study, Ag@PPE NPs demonstrated strong antibiofilm activity and antioxidant activity. Moreover, the catalytic applicability of the synthesized Ag@PPE NPs has been investigated for the oxidative hydroxylation of differently substituted aryl boronic acids into phenols at room temperature. The reaction proceeded efficiently in a short reaction time, and the desired products were obtained with high to excellent yields (82%–94%). Notably, the nanocatalyst can be recovered in five consecutive runs without decreasing its catalytic performance. The plausible mechanism of this ipso‐hydroxylation reaction is well presented.
