Herein, we describe a phytosynthetic, additive-free, economically viable, environmentally sustainable and rapid methodology for the formation of sphere-shaped Ag-SnO2 nanocomposites of 9 nm average particle size employing the stem extracts of Saccharum officinarum. Employing various spectroscopic techniques, the morphology, size, crystallinity, elemental conformation, and functional groups liable for surface stabilization as well as capping were depicted. Considerably, the Ag-SnO2 nanocomposite in aqueous phase revealed excellent removal efficiency for the abatement of four industrially emerging pollutants (Methylene Blue, Rose Bengal, Methyl Violet 6B, and 4-nitrophenol) and probable mechanisms were also suggested. Nearly, 99.1, 99.6, 99.5, and 98.4% of Methylene Blue, Rose Bengal, Methyl Violet 6B, and 4-nitrophenol were eradicated respectively, within 60, 75, 75, and 58.3 min using the synthesized nanocomposite. Moreover, the spent nanocomposites were renewed and their photocatalytic proficiencies were assessed for three consecutive cycles. The spent nanocomposite and the degraded products were respectively analyzed using X-ray diffraction and liquid chromatography-mass spectrometry spectroscopic methods. Additionally, the nanocomposite displayed comparative antimicrobial action against Pseudomonas aeruginosa, Escherichia coli, and Bacillus subtilis and indicated fair activity on 2,2-diphenyl-1-picrylhydrazyl scavenging with IC50 values 0.73 mM depicting its efficient antimicrobial and antioxidant activity. Thus, the present article has disclosed a revolutionary way for fabricating Ag-SnO2 nanocomposites and depicted their multifunctional efficacy as photocatalysts and reducing and prospective antibacterial and antioxidant agents.

Green synthesis of nanoparticles is considered an efficient method when compared with chemical and physical methods because of its bulk production, eco-friendliness and low cost norms. The present study reports, for the first time, green synthesis of silver nanoparticles (AgNPs) at room temperature using fruit extract. The visual appearance of brownish colour with an absorption band at 450 nm, as detected by ultraviolet-visible spectrophotometer analysis, confirmed the formation of AgNPs. X-ray diffraction confirmed the AgNPs to be crystalline with a face-centred lattice. The transmission electron microscopy-energy dispersive X-ray spectroscopy image showed the AgNPs are poly-dispersed and are mostly spherical and oval in shape with particle size ranging from 2 to 40 nm. Furthermore, Fourier transform-infrared spectra of the synthesised AgNPs confirmed the presence of phytoconstituents as a capping agent. The antimicrobial activity study showed that the AgNPs exhibited high microbial activity against susp. , and . The highest antimicrobial activity of AgNPs synthesised by fruit extract was observed in , susp. and with zone of inhibition, 26.67 mm.

Objective: Indian Traditional Medicine, the foundation of age-old practice of medicine in the world, has played an essential role in human health care service and welfare from its inception. Likewise, all traditional medicines are of its own regional effects and dominant in the West Asian nations; India, Pakistan, Tibet, and so forth, East Asian nations; China, Korea, Japan, Vietnam, and so forth, Africa, South and Central America. This article is an attempt to illuminate Indian traditional medical service and its importance, based on recent methodical reviews.Methods: Web search engines for example; Google, Science Direct and Google Scholar were employed for reviews as well as for meta-analysis. Results:There is a long running debate between individuals, who utilize Indian Traditional Medicines for different ailments and disorders, and the individuals who depend on the present day; modern medicine for cure. The civil argument between modern medicine and traditional medicines comes down to a basic truth; each person, regardless of education or sickness, ought to be educated about the actualities concerning their illness and the associated side effects of medicines. Therapeutic knowledge of Indian traditional medicine has propelled various traditional approaches with similar or different theories and methodologies, which are of regional significance. Conclusion:To extend research exercises on Indian Traditional Medicine, in near future, and to explore the phytochemicals; the current review will help the investigators involved in traditional medicinal pursuit.
