Facile biogenic selenium nanoparticle synthesis, characterization and effects on oxidative stress generated by UV in microalgae

Green Synthesis of Selenium Nanoparticles using Green Coffee Beans: An Optimization Study

“…under optimization conditions of pH 8, 30 °C temperature, and mixing rate 150 rpm for 24 hours were examined. As a result of images at 500 nm and 200 nm scale, SeNPs were determined to have spherical structure and mean particle size of 104.46±50.82 nm [24] …”

Influence of mesoporous iron based nanoparticles on Chlorella sorokiniana metabolism during photosynthetic biogas upgrading

“…Yang and coworkers [20] recently studied the effect of graphene oxide quantum dots on Chlorella pyrenoidosa under UV light and observed a positive effect of the growth and lipid production of this microalgae. Similarly, Dinc and coworkers [47] demonstrated that the addition of Se NPs to microalgae reduced UV-stress effects in C. vulgaris. The present study assessed the influence of UV light supplementation to visible light at different concentrations of the Fe 2 O 3 , CALPECH and SMALLOPS NPs.…”

“…Even though the mechanism of interaction of the NPs under UV light is not very clear, UV light exposure could have reduced the activity of the iron source explaining the reduced lipid and carbohydrate accumulation under UV exposure. Moreover, Dinc and coworkers [47] observed that Se NPs are effective at scavenging free radicals under UV exposure, thus the iron source of the CALPECH NPs could have the same response under UV radiation as well.…”

Biogenic synthesis of novel nanomaterials and their applications

“…Once converted into its nano-sized structure, selenium acquires very remarkable bioactive properties that make it a useful tool in biomedical sciences and other applications, such as agriculture, cosmetics, biodiesel production, and solar cells. 217 Sodium selenite is the predominant metal ion precursor used for the biogenic synthesis of selenium nanoparticles. Menon et al used the extract of ginger ( Zingiber officinale ) for the synthesis of Se nanoparticles at room temperature within 75 h. The metal ion precursor sodium selenite and the ginger extract bio-precursor were both varied at different concentrations to optimize the yield of Se nanoparticles.…”
