Cooperative Transmembrane Penetration of Nanoparticles
Physical penetration of lipid bilayer membranes presents an alternative pathway for cellular delivery of nanoparticles (NPs) besides endocytosis. NPs delivered through this pathway could reach the cytoplasm, thereby opening the possibility of organelle-specific targeting. Herein we perform dissipative particle dynamics simulations to elucidate the transmembrane penetration mechanisms of multipl...
متن کاملPathways for Skin Penetration
This paper reviews recent fi ndings about three skin penetration pathways (including a “polar pathway”) and four types of penetration enhancers (enzymes, vesicular systems, ceramides and chemical enhancers). This article will review possible ways for compounds to penetrate the skin and interact with it. Four families of enhancers will be discussed, along with their possible mechanisms of action...
متن کاملPenetration and distribution of PLGA nanoparticles in the human skin treated with microneedles.
This study was designed to investigate the penetration and the distribution of poly(d,l-lactic-co-glycolic acid) (PLGA) nanoparticles in the human skin treated with microneedles. Fluorescent nanoparticles were prepared to indicate the transdermal transport process of the nanoparticles. Permeation study was performed on Franz-type diffusion cells in vitro. The distribution of nanoparticles was v...
متن کاملIn vitro skin penetration of clobetasol from lipid nanoparticles: drug extraction and quantitation in different skin layers
Clobetasol propionate (CP) is a potent topical corticosteroid that causes several cutaneous and systemic side effects. In the present work, CP was encapsulated in nanostructured lipid carriers (NLCs) to increase drug retention in the outer skin layers and improve the safety of topical therapy. NLCs were prepared using a microemulsion technique with a mixture of lecithin, taurodeoxycholate, stea...
متن کاملShort-term safety and risk evaluation of engine oil enriched by high concentrations copper nanoparticles on the skin
Abstract Objective(s): Copper nano particles are added to ordinary engine oil as an additive to reduce friction and repair damaged surface under friction conditions. However, it is still unclear what environmental effects such a compound might have on conventional engine oils and its toxicity in different animal species has not been determined. The aim of this study is to investigate the ...
