This work aimed to assess the effect of Syzygium nervosum leaf extract as a reducing agent for green synthesis of AgNPs on HT through an optimizing process using response surface methodology (RSM) and the Box‐Benken model. The optimal conditions for synthesis of AgNPs on HT include reaction time of 6.15 hours, reaction temperature of 50 oC and the ratio of diluted Syzygium nervosum leaf extract to reduce AgNO3 of 50.37 mL/mg. Under the optimal conditions, the yield of reduction reaction reached 77.54 %, close to the theoretical value of 76.97 %. Besides, the morphology, density, and characteristics of AgNPs on the surface of HT layers have been determined by using Ultraviolet‐visible spectroscopy, Field emission scanning electron microscopy, High resolution transmission electron microscopy, selected area diffraction, X‐ray diffraction, Dynamic light scattering, Infrared spectroscopy, Fluorescence emission spectroscopy, Brunauer‐Emmett‐Teller methods. The spherical AgNPs were synthesized successfully on the surface of HT with the average particle size of 13.0 ± 1.1 nm. Interestingly, HT‐Ag hybrid materials can inhibit strongly the growth of E. coli, S. aureus as well as two antibiotic resistance bacterial strains, P. stutzeri B27 and antibiotic resistance E. coli. Overall, the HT‐Ag hybrid materials are very promising for application in practice.

The green synthesis of inorganic nanoparticles using plant extracts has been an important strategy to mitigate the uses of hazardous chemicals and thus reduce toxic by-products. We herein report for the first time the synthesis of silver nanoparticles (AgNPs) utilizing Vitis heyneana fruit peel as a key agent. Specifically, oleanolic acid was found in the extract and its crucial role as both reducing and stabilizing agent was experimentally evidenced. The as-synthesized AgNPs were morphologically and structurally characterized to possess quasi-spherical shapes with an average diameter of 11 nm and exhibit polycrystalline nature. Bioactive studies indicated that as-synthesized AgNPs revealed potent antimicrobial activities against Lactobaccillus plantarum, Pseudomonas aeruginosa, and Aspergillus flavus, demonstrating an IC50 value of 20.00 ± 2.05 μg ml−1 and a MIC value of 32 ± 0.03 μg ml−1 (against Pseudomonas aeruginosa); the NPs also possessed superior antioxidant activities with an IC50 value of 23.22 ± 1.25 μg ml−1 compared to vitamin C (18.23 ± 0.15 μg ml−1). The AgNPs further revealed capabilities of colorimetrically detecting Hg2+ ions with a limit of detection of 0.048 μM and a limit of quantitation of 0.16 μM. These findings therefore suggest promising uses of the phytosynthesized AgNPs in nanomedicine and sensing technology.
