Eco-friendly synthesis of gold nanoparticles using carboxymethylated gum Cochlospermum gossypium (CMGK) and their catalytic and antibacterial applications

Plant Gum Based Drug Carriers

“…Antibacterial activity of Kondagogu gum loaded with AuNPs against Escherichia coli and Bacillus subtilis is reported to be excellent [21].…”

“…E. coli and B. subtilis [21] and 5 μg of Gum Tragacanth loaded with silver nanoparticles were added to the center well with a diameter of 6 mm. Culture plates loaded with discs of antibiotic, erythromycin (15 μg/disc) were included as positive controls.…”

Fluorine-free synthesized tantalum carbide (Ta2C Mxene) as an efficient electrocatalyst for water reduction and nitro compound reduction

“…Moreover, the green reduction of the highly pollutant 4-nitrophenol has great significance in the industrial production of 4-aminophenol. 12,13 Nevertheless, the majority of approaches merely collect harmful substances and necessitate additional calcination treatment, like adsorption, to effectively eradicate 4-NP. As compared to other techniques, catalytic hydrogenation is the most eco-friendly, effective, and feasible way to convert 4-NP to 4-AP.…”

Advancement of Microwave-Assisted Biosynthesis for Preparing Au Nanoparticles Using Ganoderma lucidum Extract and Evaluation of Their Catalytic Reduction of 4-Nitrophenol

“…Many studies reported that the rate of synthesizing metallic nanoparticles could be significantly higher using assistance techniques such as heat-treatment, gamma irradiation, ultrasonication, , hydrothermal, , and microwave irradiation. , Among these assistance techniques, microwave-assisted synthesis has been receiving attention as an inexpensive heating method because of its short reaction time, low cost, and high product output . Thus, electromagnetic waves with irradiation ranging from 300 MHz to 300 GHz (corresponding to the wavelength varying from 1 m to 1 mm) and microwave irradiation could directly interact with molecules and accelerate them.…”

“…Many studies reported that the rate of synthesizing metallic nanoparticles could be significantly higher using assistance techniques such as heat-treatment, 24 gamma irradiation, 25 ultrasonication, 26,27 hydrothermal, 28,29 and microwave irradiation. 30,31 Among these assistance techniques, microwaveassisted synthesis has been receiving attention as an inexpensive heating method because of its short reaction time, low cost, and high product output.…”
