Application of organic nanotubes (ONTs) into drug nanocarriers ultimately requires validation in live animals. For improving the dispersibility in biological media and in vivo distribution, the outer surface of an ONT was functionalized with polyethylene glycol (PEG) via the coassembly of an ONT-forming lipid with 5-20 mol% of a PEG-tethered lipid analogue (PEG-lipid). Firstly, the effect of PE...

Nanosilver (AgNPs) can be synthesized using plant extracts that safe, simple, and environmentally friendly. Sweet orange contains flavonoids citric acid, which a bioreductor capping agent in silver biosynthesis to increase antimicrobial activity. AgNPs are then dispersed gel for acne treatment through peel-off mask preparation. Humectants provide moisture, prevent skin irritation regulate the v...
