Force Spectroscopy Mapping of the Effect of Hydration on the Stiffness and Deformability of Phytoglycogen Nanoparticles
Biomacromolecules. 2021 Jun 4. doi: 10.1021/acs.biomac.1c00399. Online ahead of print.ABSTRACTPhytoglycogen is a naturally occurring glucose polymer that is produced by sweet corn in the form of compact nanoparticles with a dendritic or tree-like architecture. The soft and porous nature of the nanoparticles, combined with their biodegradability and lack of toxicity, makes them ideal for a broad range of applications in personal care, nutrition, and biomedicine. To fully exploit these applications, it is necessary to understand the complex properties of the soft, hydrated nanoparticles in detail. In the present study, we ha...

Phytofabrication of Selenium Nanoparticles From Emblica officinalis Fruit Extract and Exploring Its Biopotential Applications: Antioxidant, Antimicrobial, and Biocompatibility
Conclusion The present study shows phytofabrication of SeNPs from aqueous fruit extract of E. officinalis by facile, green, economic, and eco-friendly approach. The aqueous fruit extract of E. officinalis was rich with phenolics, flavonoids, and tannins, and was found appropriate for biosynthesis of nanoparticles. The synthesized PF-SeNPs exhibited highly stable, negative charge, amorphous nature, spherical shape and nano-size. The PF-SeNPs has presented efficient bio-potential applications, i.e., antioxidant, antimicrobial, and biocompatibility. The PF-SeNPs has shown potent free radical scavenging activity and it was fo...

Sustainable and green trends in using plant extracts for the synthesis of biogenic metal nanoparticles toward environmental and pharmaceutical advances: A review
Environ Res. 2021 Jul 7:111622. doi: 10.1016/j.envres.2021.111622. Online ahead of print.ABSTRACTConventionally utilized physical and chemical routes for constructing nanoparticles are not eco-friendly. They are associated with many shortcomings like the requirement of specially designed equipment, templates, extremely high temperature, and pressure. Biosynthesis seems to be drawn unequivocal attention owing to its upsurge of applications in different fields like; energy, nutrition, pharmaceutical, and medicinal sciences. To harness the biological sources, the present review describes an environment-friendly route to gener...

Metallic nanoparticles photodegraded antibiotics and co-application improved wheat growth and nutritional quality through stress alleviation
Chemosphere. 2023 Feb 20:138189. doi: 10.1016/j.chemosphere.2023.138189. Online ahead of print.ABSTRACTAntibiotics are now considered as emerging environmental pollutants due to their persistent nature and continuous exposure through irrigation with wastewater contaminated with antibiotics. The aim of present study was to assess the potential of nanoparticles for photodegradation of antibiotics and subsequent stress alleviation via Titania oxide (TiO2) application for improvement in crop productivity and quality in terms of nutritional composition. In the first phase, different nanoparticles, TiO2, Zinc oxide (ZnO) and Iro...

Cytotoxic Potential of < em > Diospyros villosa < /em > Leaves and Stem Bark Extracts and Their Silver Nanoparticles
Plants (Basel). 2023 Feb 8;12(4):769. doi: 10.3390/plants12040769.ABSTRACTDiospyros villosa is traditionally used for an anti-bacterial property. Its cytotoxic effects have not been studied before. Therefore, this study aimed to examine the nutritional properties as well the cytotoxic effects of D. villosa. The leaves and stem barks were subjected to three different extraction methods (methanol, chloroform and hexane) and their nanoparticles were synthesized at two different temperatures (room temperature and at 80 °C). Thereafter, extracts were assessed using the associated AOCC protocols, for their nutritional content (...
