“…Presently, there has been a surge in the study of nanotechnology due to the distinct properties shown by materials at the nanoscale [1]. Nano particles's physical, chemical, and biological properties, have resulted in their growing application in the fields of electronics, medicine, environment, packaging, industry, antimicrobial agents, and catalysts [2][3][4]. Several physical and chemical techniques have been developed to produce nanoparticles, such as co-precipitation, sol-gel processing, microemulsions, hydrothermal/solvothermal methods, and others.…”

Biosynthesised silver nanoparticles (AgNPs), especially those synthesised by plant extracts, are extensively utilised in the fields of pharmacy and medicine due to their ability to exhibit a wide range of biological functions. The current study is focused on the green synthesis of silver nanoparticles from various concentrated silver nitrate solutions using turnip root extract as a reducing and stabilising agent and to assess the in vitro antibacterial efficacy of these AgNPs. For the study, we employed microwave-assisted reduction to examine the impact of microwave energy on the resulting AgNPs in comparison to the conventional heating method. X-ray diffraction analysis revealed the crystalline nature of the as-prepared AgNPs, while field emission-scanning electron microscopy (FE-SEM) showed the majority of spherical-shaped AgNPs had an average grain size of 47.5 nm. Energy-dispersive X-ray spectroscopy (EDX) indicates the high weight percentage of the produced AgNPs than for extract residue, especially for the AgNPs that are prepared with microwave assistance. Fourier transform infrared spectroscopy (FTIR) was used to reveal the functional groups that are related to many phytochemical compounds, such as alkaloids, flavonoids, and terpenoids, which act as reducing and stabilizing agents. High zeta potential measures (-22.77 and -38.83 mv) approved the high stability of the synthesised AgNPs as higher zeta potentials typically correlate with greater stability. The antibacterial activity behaviour of the produced NPs against gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria was significantly acceptable for both heating techniques, as observed from the measured inhibition zone.

Many researchers are focusing on the eco-friendly and cost-effective green synthesis of materials for removing heavy metals from wastewater using materials made from natural sources. In this research, date syrup was used as a rich carbon source while potassium chloride particles were used as a substrate. Green synthesized silver nanoparticles modified the graphene foam to enhance its heavy metal removal and antibacterial efficiency. The morphology and structure of the graphene foam were examined using scanning electron microscopy and Raman spectroscopy. The Brunauer-Emmett-Teller method examines textural features such as surface area, pore volume and diameter. The study focused on evaluating the efficiency of removing heavy metals including cadmium, lead, zinc, and chromium from water. The results indicated that the date syrup graphene foam has high heavy metal removal efficiency despite the short contact time, especially for Cd2+ and Pb2+, with removal efficiencies of 68% and 39%, respectively. It shows a relatively lower efficacy for Zn2+ and Cr2+, with removal efficiencies of 10% and 27%, respectively. The addition of silver nanoparticles greatly improved the removal efficiency of Cd2+ (75%), Zn+2 (22%), and Cr2+ (33%). Moreover, the antibacterial efficacy test showed significant improvement after the nanosilver modification to reach a 100% bacterial-killing rate.
