The work presented here aims at developing a microfluidic device for automated sample enrichment of water samples. The device is optimized for the analysis of small organic pollutants by biosensing and environmental monitoring applications. Miniaturization and automation of solid phase extraction with our device enabled us to reduce the volume of sample and of eluent significantly, resulting in...

For drugs with short half-lives, transdermal delivery provides a continuous noninvasive mode of administration. For charged drug molecules, the transdermal delivery can be assisted by the application of direct constant current, which drives the drug through the skin by electrostatic repulsion (method called iontophoresis) [1]. An important component of a drug delivery patch is the artificial me...

Abstract Enhancing the proton conductivity of exchange membranes (PEMs) is essential to expand applications membrane fuel cells (PEMFCs). Inspired by conduction mechanism bacteriorhodopsin, cucurbit[ n ]urils (CB[ ], where number glycoluril units, = 6, 7, or 8) are introduced into sulfonated poly(ether ether ketone) (SPEEK) matrix fabricate hybrid PEMs, employing a nature-inspired chemical engi...
