Photo-irradiation coupled biosynthesis of magnesium oxide nanoparticles for antibacterial application

Green approaches for the synthesis of metal and metal oxide nanoparticles using microbial and plant extracts

“…170 Recently, solar energy has been used as a potential alternative for the heating process to yield biosynthesized nanoparticles. 289 Likewise, light sources, such as ultraviolet, microwave, 290 gamma 291 and visible light, 292 have been introduced as an effective nanocatalyst to form nanoparticles rapidly, instead of a chemical catalyst. Besides, efforts have been taken to identify the specific biomolecule, enzyme or phytochemical responsible for nanoparticle formation via chromatographic or mass spectroscopic techniques.…”

Methods for Green Synthesis of Metallic Nanoparticles Using Plant Extracts and their Biological Applications - A Review

“…In one method, 10 mL leaf extract of Amaranthus tricolor L. was added to 90 mL of 0.001 M magnesium acetate tetrahydrate [Mg(CH 3 COO) 2 .4H 2 O]. The mixture was kept on a hotplate for 10 min at 60°C [115]. In another method (as shown in Fig.…”

“…MgO NPs have been used in several applications viz., antifungal, antibacterial as well as catalytic activity and dye degradation. Biologically synthesized MgO NPs from plant extracts of Amaranthus tricolor L [115], Bauhinia purpurea L [117], Swertia chirayta H. Karst [118] and Tectona grandis L [119] have shown antibacterial activity against several bacteria such as E. coli, S. aureus and K. pneumonia. MgO NPs from plant extracts of Pisonia grandis R. Br [120] and Withania somnifera L [121] have exhibited antifungal activity against C. albicans.…”
