The objective of this study is to determine the effect of iontophoresis on the transport of lidocaine hydrochloride (2%, w/w) across ear pig skin. Our project consists of the development of a transdermal drug delivery system (TDDS). The system is designed as a reusable electronic patch where micropump, reservoir, sensors and Bluetooth communication are integrated. Therefore, quantify the iontophoretic...
SAXS/WAXS studies were performed in combination with freeze fracture electron microscopy using mixtures of a new Gemini catanionic surfactant (Gem16-12, formed by two sugar groups bound by a hydrocarbon spacer with 12 carbons and two 16-carbon chains) and the zwitterionic phospholipid 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) to establish the phase diagram. Gem16-12 in water forms bilayers...
Monolayers at the air/water interface are used as 2D models of biological membrane to study the interaction of a new Gemini catanionic surfactant, Gem16,12, with the phospholipid DPPC. Gem16,12 is a synthetic analog of galactosylceramide (a cell receptor for HIV-1) and shows both good anti-HIV activity and low toxicity. Adsorption kinetics measurements are performed at Gemini concentrations below...
