Synthesis and Characterization of Nano Selenium Using Plant Biomolecules and Their Potential Applications

Green synthesis of selenium nanoparticles mediated from Ceropegia bulbosa Roxb extract and its cytotoxicity, antimicrobial, mosquitocidal and photocatalytic activities

“…These reflection plans shows the diffraction peaks were well synchronized and were confirmed with JCPDS (Joint Committee on Powder Diffraction Standards) file no. 06-0362 files, evidently representing the crystalline nature of SeNPs which is in agreement with the works of Alam et al 14 , showing SeNPs obtained from Withania somnifera leaf aqueous extract were crystalline in nature. The SeNPs morphology was confirmed by Field Emission Scanning Electron Microscope (FE-SEM) and High-Resolution Transmission Electron Microscope (HR-TEM) analysis.…”

“…According to Wadhwani et al 12 statement, biologically mediated SeNPs are safer, environmental friendly and economically viable when compared with other approaches (chemically and physical). At the same time, reports are available on biological approach to produce SeNPs via plants part such as dried leaf, seed, flowers and bark 13 , 14 . The Ceropegia bulbosa Roxb.…”

Phytofabrication of Selenium Nanoparticles From Emblica officinalis Fruit Extract and Exploring Its Biopotential Applications: Antioxidant, Antimicrobial, and Biocompatibility

“…Despite the fact, that a large number of plants are reported for nanoparticle synthesis, only few reports are available on phytogenic synthesis of SeNPs. These studies include synthesis using leaf extract of Capsicum annuum (Li et al, 2007), seed extract of fenugreek (Ramamurthy et al, 2013), leaf extract of lemon (Prasad et al, 2013), dried fruit extract of Vitis vinifera (Sharma et al, 2014), leaf extract of Terminalia arjuna (Prasad and Selvaraj, 2014), flower extracts of Bougainvillea spectabilis (Deepa and Ganesan, 2014), leaf extract of Leucas lavandulifolia (Kirupagaran et al, 2016), leaf extract of Clausena dentate (Sowndarya et al, 2017), aqueous extract of Allium sativum (Anu et al, 2017), leaf extracts of Diospyros montana (Kokila et al, 2017), leaf extracts of Psidium guajava (Alam et al, 2018), polysaccharides from Lycium barbarum and green tea extracts (Zhang et al, 2018). In this study, we report for the first time, a quick synthesis of phytofabricated selenium nanoparticles (PF-SeNPs) from fruit extract of Emblica officinalis and establishment of biocompatibility of PF-SeNPs relating with cytotoxicity of precursor sodium selenite.…”

Biomedical Potential of Plant-Based Selenium Nanoparticles: A Comprehensive Review on Therapeutic and Mechanistic Aspects

“…The toxicity and the activity of selenium are usually impacted by the high-dose, so it is very important to control the therapeutic dose. 11,12 Additionally, the high dose of sodium selenite, selenocysteine, and methyl selenium exhibit excellent therapeutic potential but on the other hand has serious toxicity problems. 2,13,14 Keeping in view, the above-mentioned high doses of selenium problems, nanotechnology has emerged as an ebullient sphere of science that evinces potential therapeutic applications in medical and nonmedical sectors.…”

“…3 The nano-sized selenium has attracted a great deal of interest worldwide as food additives especially, in those individuals suffering from selenium deficiencies but also as an important therapeutic agent without significant side effects in medicine. 13,15,16 Additionally, the plant-based SeNPs have excellent potential in sensory probe, 17 targeted delivery of therapeutic drugs, 18 anticancer agents, 19 detection of heavy metals, 20 and have significant antimicrobial properties 12 (Figure 1). Several physical and chemical techniques have been employed, that requires the utilization of various chemical compounds and physical approaches to synthesize SeNPs.…”
