Despite ongoing public health measures and increasing vaccination rates, deaths disease severity caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) its new emergent variants continue to threaten the of people around world. Therefore, there is an urgent need develop novel strategies for research, diagnosis, treatment, government policies combat variant strains SARS-CoV-2. Sin...
528 nature nanotechnology | VOL 3 | SEPTEMBER 2008 | www.nature.com/naturenanotechnology Interestingly, the nano-selenium material captured five times more mercury than the maximum predicted on the basis of its surface area, indicating significant penetration of mercury into the nanoselenium matrix. This did not occur in the other sorbent materials. Even so, the amount of mercury sequestered wa...
The present study was (i) to prepare two types of selenium nanoparticles, namely an amorphous form of selenium quantum dots (A-SeQDs) and a crystalline form of selenium quantum dots (C-SeQDs); and (ii) to investigate the nano-bio interactions of A-SeQDs and C-SeQDs in MCF-7, HepG2, HeLa, NIH/3T3, L929 cells and BRL-3A cells. It was found that A-SeQDs could induce the mitochondria-mediated apopt...
In the present study, selenium (Se) nanoclusters were grown through heterogeneous nucleation on titanium (Ti) surfaces, a common orthopedic implant material. Normal healthy osteoblasts (bone-forming cells) and cancerous osteoblasts (osteosarcoma) were cultured on the Se-doped surfaces having three different coating densities. For the first time, it is shown that substrates with Se nanoclusters ...
