In the present study, aqueous leaf extract of Strobilanthes cordifolia J.R.I.Wood was combined with silver nitrate to synthesis silver nanoparticles (AgNPs). The AgNPs were characterized using visible spectroscopy (UV), X-ray diffraction (XRD), Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), energy dispersive X-ray (EDaX), particle size analysis, and transmission electron microscope (TEM). The UV spectrum absorption peak occurred at 438 nm. The FTIR analysis of the AgNPs indicated the presence of functional groups such as aldehyde, alkenes, and carboxylic acids. The crystalline structure of AgNPs was confirmed by XRD. The AgNPs have a spherical shape according to SEM. The AgNPs components composition was confirmed by EDaX. The particle size distribution of AgNPs is monodispersion in the range at 42.54 nm. TEM demonstrated the AgNPs size to be between 11.35 and 34.90 nm. The AgNPs exhibited good antibacterial property against Escherichia coli and Staphylococcus aureus. The antioxidant activity of the AgNPs was represented by increased DPPH, ABTS, and H 2 O 2 activities.The antidiabetic activity of the AgNPs was indicated by the inhibition of α-amylase and α-glycosidase and antiinflammatory highest albumin denaturation and HRBC membrane stabilization properties. Further, the AgNPs also significantly inhibited the MCF-7 cell lines. These results clearly suggest that the synthesized AgNPs using S. cordifolia leaves could have several potential biomedical applications.

“…In the case of materials containing AgNPs, the wavelength at which the highest absorption in the UV‐Vis spectra occurs depends on the composition of the NPs. 25 Almost similar UV absorption peaks were reported for NPs synthesizing using Annona senegalensis (431 nm) 26 and Stachys byzantina (441 nm). 27 …”

Antibiotic resistance against infections caused by microbes has emerged as a global challenge resulting in longer hospitalizations and higher medical cost and mortality. The excessive use of antibiotics has led to the swift progression of antibiotic resistance in bacterial strains. Metallic and metal oxide (M/MO) nanoparticles (NPs) have the potential to provide a pertinent alternative to antibiotics as they interact with the critical cellular organelles and biomolecules such as DNA, enzymes, ribosomes, and lysosomes. This affects the permeability of the cell membrane causing oxidative stress, gene expression, protein activation, and enzyme activation restricting the habitat of microbes. Further, NPs simultaneously target multiple biomolecules at once making them an efficient antibacterial agent against which microbes are unable to develop resistance easily, although the toxicity associated with the M/MO NPs still remains a key challenge for clinical uses. Green synthesis provides an efficient solution to reduce the toxic effects associated with these NPs as it does not use harsh chemicals and environment for the synthesis of NPs. In this work, we have provided a comprehensive review of the green synthesis of M/MO NPs using plants (roots, seeds, barks, flowers) and microbes (bacteria, fungi, algae). The yield of the NPs achieved from the green synthesis is lower than that of conventional methods and significant advancements have been made recently which are delineated in this review for different M/ MO NPs. Further, the mechanism of NP interaction with the microbes and their different antimicrobial applications have been discussed in detailed. The present review aims to provide a critical overview of the current state of the large-scale synthesis of the M/ MO NPs as well as their different antimicrobial activities.

Nanotechnology is gaining enormous attention as the most dynamic research area in science and technology. It involves the synthesis and applications of nanomaterials in diverse fields including medical, agriculture, textiles, food technology, cosmetics, aerospace, electronics, etc. Silver nanoparticles (AgNPs) have been extensively used in such applications due to their excellent physicochemical, antibacterial, and biological properties. The use of plant extract as a biological reactor is one of the most promising solutions for the synthesis of AgNPs because this process overcomes the drawbacks of physical and chemical methods. This review article summarizes the plant‐mediated synthesis process, the probable reaction mechanism, and the colorimetric sensing applications of AgNPs. Plant‐mediated synthesis parameters largely affect the surface plasmon resonance (SPR) characteristic due to the changes in the size and shape of AgNPs. These changes in the size and shape of plant‐mediated AgNPs are elaborately discussed here by analyzing the surface plasmon resonance characteristics. Furthermore, this article also highlights the promising applications of plant‐mediated AgNPs in sensing applications regarding the detection of mercury, hydrogen peroxide, lead, and glucose. Finally, it describes the future perspective of plant‐mediated AgNPs for the development of green chemistry.
