Nanoparticles On My Mind
By KIM BELLARD
Nanoparticles are everywhere! By that I mean, of course, that there seems to be a lot of news about them lately, particularly in regard to health and healthcare. But, of course, literally they could be anywhere and everywhere, which helps account for their potential, and their potential danger.
Let’s start with one of the more startling developments: a team at the University of Miami’s College of Engineering, led by Professor Sakhrat Khizroev, believes it has figured out a way to use nanoparticles to “talk” to the brain without wires or implants. They use “a novel clas...

Nanoparticles as an effective drug delivery system in COVID-19
CONCLUSION: Our current studies reveal that nanoparticles may prove very helpful in the delivery of drugs for Covid-19 treatment. Many cases showed that patients, where drugs are delivered with the help of nanoparticles, produced very few side effects.PMID:34649334 | DOI:10.1016/j.biopha.2021.112162

Ultrafine Ni-B nanoparticles for efficient hydrogen evolution reaction
Publication date: December 2019Source: Chinese Journal of Catalysis, Volume 40, Issue 12Author(s): Ting Huang, Tao Shen, Mingxing Gong, Shaofeng Deng, Chenglong Lai, Xupo Liu, Tonghui Zhao, Lin Teng, Deli WangAbstractThe search for active, stable, and cost-effective electrocatalysts for hydrogen evolution reaction (HER) is desirable, but it remains a great challenge in the overall water splitting. Here, we report the synthesis of nickel boron nanoparticles supported on Vulcan carbon (Ni-B) via a simple, yet scalable, two-step chemical reduction–annealing strategy. The results of the electrochemical measurements suggest t...

Potential of < em > Azadirachta indica < /em > as a Capping Agent for Antiviral Nanoparticles against SARS-CoV-2
Biomed Res Int. 2022 Sep 15;2022:5714035. doi: 10.1155/2022/5714035. eCollection 2022.ABSTRACTA rare type of pneumonia later on referred to as COVID-19 was reported in China in December 2019. Investigations revealed that this disease is caused by a coronavirus previously identified as SARS-CoV-2, and since then, it has become a global pandemic with new strains emerging rapidly as a result of genetic mutations. Various therapeutic options are being explored in order to eradicate this pandemic even though approved vaccine candidates are being currently rolled out globally. Most medicinal plant extracts have astonishing prope...

Biogenic Synthesis of Silver Nanoparticles Using Phyllanthus emblica Fruit Extract and Its Inhibitory Action Against the Pathogen Acidovorax oryzae Strain RS-2 of Rice Bacterial Brown Stripe
Conclusion
In conclusion, this study clearly provides an economical, environmental friendly, and straightforward reproducible approach in AgNPs synthesis employing P. Emblica fruit extracts as a reducing, stabilizing, and capping agent. The biosynthesized AgNPs were characterized thoroughly by UV-Visible and Energy Dispersive X-Ray Spectroscopy, X-Ray diffraction, FTIR, TEM, HRTEM and SEM. The FTIR results found several phytochemicals responsible for the rapid reduction of ions, leading to AgNPs formation. Especially, hydroxyl groups oxidation of hydrolysate, which likely stimulated the formation of nanoparticles. In the ...

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...

Supramolecular self-assembled AIE molecules are used in the search for target proteins in norcantharidin
Anal Chim Acta. 2023 Jan 25;1239:340642. doi: 10.1016/j.aca.2022.340642. Epub 2022 Nov 18.ABSTRACTNorcantharidin (NCTD), a demethylated derivative of cantharidin, is an anticancer active component in traditional Chinese medicine. At present, the main methods for finding its target proteins are pharmacological methods and biophysical screening, which cannot achieve the purpose of efficient and accurate screening. Here we established a new analytical method for specific fishing and assisted imaging for norcantharidin target proteins. For the AIE supramolecule probe, the benzophenone azide (BPA) fluorescent nanoparticles with...
