Gum tragacanth-mediated synthesis of metal nanoparticles, characterization, and their applications as a bactericide, catalyst, antioxidant, and peroxidase mimic

Abstract Among biogenic methods employed for synthesizing various nanoparticles (NPs), gum tragacanth (TGC)-mediated NP production is important. The TGC not only qualifies the principles of green chemistry but also embraces unique qualities. In this perspective, current review concentrates on composition, uses, and exploitation towards metal silver (Ag), gold (Au), palladium (Pd), platinum (Pt), their characterization (UV-visible absorption spectroscopy, X-ray diffraction, Fourier transform infrared transmission electron microscopy). addition, applications synthesized as a bactericide, catalyst, antioxidant, peroxidase mimic are emphasized. Ag (13 nm) showed antibacterial action against Gram-negative Gram-positive bacteria at 2–12 μg‧mL −1 . bactericide makes it candidate choice medicinal pharmacological applications. catalytic activity Pd (14 demonstrated borohydride reduction methylene blue. reduced/capped oxide serve redox photocatalysts remediation toxic pigments dyes in industrial effluents. At 15 , exhibited 1,1-diphenyl-2-picrylhydrazyle radical scavenging (95.8%) served an artificial enzyme colorimetric sensing hydrogen peroxide. other TGC-based nanocomposites, such heavy sorption, wound dressing, drug carrier, tissue engineering, etc., mentioned.
