T he present study reports wound healing potential of silver nanoparticles (AgNPs) hydrogel using Arnebia nobilis (A. nobilis) root extract. It makes a convenient method for the green synthesis of AgNPs and evaluated for its wound healing activity. Silver has been used for the treatment of medical ailments for over 100 years due to its natural antibacterial and antifungal properties. The synthesized nanoparticles were characterized using UV-visible spectrophotometer; transmission electron microscopy, X-ray diffraction (XRD), scanning electron microscopy, and Fourier transform infra-red spectrometry. The nanoparticles were found to be mostly spherical in shape. XRD study shows that the particles are crystalline in nature with face centered cubic geometry. The synthesized AgNPs exhibited good antibacterial potential against both Gram-positive and Gram-negative bacterial strain as measured using well diffusion assay. The recent emergence of nanotechnology has provided a new therapeutic modality in AgNPs for use in wounds. We investigated the wound-healing potential of AgNPs hydrogel using A. nobilis root extract in an excision animal model. The study showed that hydrogel of AgNPs using A. nobilis root extract exert positive effect due to their antimicrobial potential. The results provide insight into the mechanism of actions of AgNPs and have provided a novel therapeutic direction for wound treatment in the clinical practice.

In the recent past, bismuth oxyhalides (BiOX) have been widely used for the photocatalytic degradation of the organic pollutants and other environmental remediation because of their higher stability, economic viability, nontoxicity and effective charge separation. We begin with the review of the different approaches adopted so far for BiOX (X = Cl, Br, and I) synthesis and a study of their photocatalytic performances under UV and visible light towards the various organic as well as inorganic pollutants. Later on, a study on further enhancement of the efficiency of BiOX under UV and visible light irradiation using recent advancements would be presented. The new approaches involve controlled morphology by forming composite and hybrid materials with other semiconductors and also doping with other metals and nonmetals that would undoubtedly be beneficial in the interfacial charge transfer and efficient inhibition of the photo-generated species. Herein, we would also exploit the recent developments in the research strategies for enhancing photocatalytic activity of BiOX.

The use of plant extract eliminates the usage of harmful chemicals and serves as an eco-friendly approach for environmental remediation.
