Journal ArticleDOI

Targeted crystallization of mixed-charge nanoparticles in lysosomes induces selective death of cancer cells

TL;DR: It is shown that mixed-charge nanoparticles covered with certain ratios of positively and negatively charged ligands can selectively target lysosomes in cancerous cells while exhibiting only marginal cytotoxicity towards normal cells.
Journal ArticleDOI

Oxidative Nanopeeling Chemistry-Based Synthesis and Photodynamic and Photothermal Therapeutic Applications of Plasmonic Core-Petal Nanostructures

TL;DR: Near-infrared laser-activated CPNs can optically monitor and efficiently kill cancer cells via apoptotic pathway by dual phototherapeutic effects and ROS-mediated oxidative intracellular damage with a relatively mild increase in temperature, low laser power, and short laser exposure time.
Journal ArticleDOI

Photoactive Antiviral Face Mask with Self-Sterilization and Reusability.

TL;DR: This dual-channel spray-assisted nanocoating hybrid of shellac/copper nanoparticles (CuNPs) to a nonwoven surgical mask showed outstanding photoactivity for antimicrobial action, conferring reusability and self-sterilizing ability to the masks.
Journal ArticleDOI

Screening and isolation of halophilic bacteria producing industrially important enzymes

TL;DR: It is concluded that these halophilic isolates are not only diverse in phylogeny but also in their enzyme characteristics and may be potentially useful for catalysis under harsh operational conditions encountered in industrial processes.
