DESIGN, PREPARATION AND CHARACTERIZATION OF SILVER NANOPARTICLE CONTAINING HERBAL PLANT EXTRACT OF CAMPSIS GRANDIFLORA AND ITS ANTI-BACTERIAL ACTIVITY
Abstract
ABSTRACT
Nanotechnology has emerged as one of the most promising fields in pharmaceutical and biomedical sciences owing to its wide range of applications in drug delivery, diagnostics, antimicrobial therapy, and tissue engineering. Among various metallic nanoparticles, silver nanoparticles (AgNPs) have gained remarkable attention because of their potent antibacterial, antioxidant, anti-inflammatory, and wound healing properties. Green synthesis of silver nanoparticles using medicinal plant extracts has become an attractive alternative to conventional physical and chemical methods because it is eco-friendly, cost-effective, and biocompatible. Campsis grandiflora is a medicinally important plant rich in phytoconstituents such as flavonoids, phenolics, tannins, alkaloids, and terpenoids, which act as natural reducing and stabilizing agents during nanoparticle synthesis. Silver nanoparticles synthesized using Campsis grandiflora extract exhibit enhanced antibacterial activity against several pathogenic microorganisms including Gram-positive and Gram-negative bacteria. This review article discusses the design, green synthesis, preparation methods, physicochemical characterization, and antibacterial evaluation of silver nanoparticles containing Campsis grandiflora extract. The article also highlights the mechanisms of antibacterial action, factors influencing nanoparticle synthesis, and potential pharmaceutical and biomedical applications of these nanomaterials. The synergistic interaction between silver nanoparticles and plant-derived phytochemicals makes these systems promising candidates for the development of advanced antimicrobial formulations.
