Article Abstract

The aim of the present study was to prepare chitosan nanoparticles to evaluate their effect on protection of rice plants from blast fungus. Nanoparticles were prepared using the ionic gelation method by the interaction of Chitosan and sodium tripolyphosphate. The particle size, polydispersity index, zetapotential and structure was confirmed by DLS, FTIR, TEM and XRD. The Chitosan nanoparticle was evaluated for suppression of rice blast fungus (Pyricularia grisea) under the detached leaf condition. It is evident from our results that chitosan nanoparticle have potential in suppressing blast disease of rice which can be used further under field condition to protect rice plants from the devastating fungus.

This review highlights the integration of drug repurposing and nanotechnology-driven delivery strategies as innovative approaches to enhance the antifungal activity of statins against mucosal candidiasis, providing a framework for future translational research and clinical application. The rising prevalence of antifungal resistance and virulence factors of Candida albicans underscore the limitations of current therapies. Statins, commonly used as lipid-lowering agents, have emerged as attractive repurposed drug candidates due to their ability to interfere with fungal ergosterol biosynthesis and Ras-mediated signaling pathways.

Chronic wounds, particularly in diabetic patients, are characterized by prolonged inflammation, impaired angiogenesis, and delayed tissue regeneration. To address these challenges, the author developed a bioactive scaffold by incorporating quercetin nanoparticles (Qn) into a chitosan/silk fibroin (ChS) matrix, aiming to accelerate and enhance the wound healing process. Quercetin nanoparticles were synthesized via a solvent displacement method and incorporated into a ChS scaffold using a blending and freeze-drying technique.

Bone defect therapy frequently encounters bacterial infections and chronic inflammation, which impair bone regeneration and threaten implant stability. Iron oxide nanoparticles have attracted attention due to cost-effectiveness, biocompatibility, and metabolic safety. However, iron oxide nanoparticles still struggle to balance low-temperature efficient antibacterial activity, effective immunomodulation, and bone regeneration.

Bacterial infection in the injured skin may threaten the wound repair and skin regeneration owing to aggravated inflammation. The multifunctional dressings with persistent antibacterial activity and improved anti-inflammatory capability are urgently required. Herein, a type of heterogeneous zinc/catechol-derived resin microspheres (Zn/CFRs) composed of zinc ions (Zn) and zinc oxide (ZnO) nanoparticles was developed to impart the methacrylamide chitosan (CSMA)-oxidized hyaluronic acid (OHA) hydrogel with a persistent Zn release behavior.
