Several washing agents ( EDTA, CDTA, NTA, 8 HQS, Ti-EDTA- citrate, Ca2+, and H+) were tested for their ability to extract adsorbed metal from biological surfaces to distinguish between internalized and total cellular metal (Pb, Ni, Cd, Zn, and Cu) for a gr ...
Lipophilicity of compounds with therapeutic interest represents one of the most important physicochemical parameters in predicting and interpreting transport processes across biological barriers. This property is commonly measured as a drug | membrane part ...
The steady-state electrical behavior of cation-selective ionophore membranes with different kinds of ionic additives was studied on a theoretical basis. Membranes with both mobile and fixed anionic sites exhibit nonlinear current-voltage curves, which is i ...
We report about the development of a planar support for biological samples. The aim is to combine AFM and patch-clamp measurements, in order to perform simultaneous measurements of topography and electrical properties of biological membranes. Sub-micromete ...
The scope of this work has been the design of a mechanical actuator in polydimethylsiloxane (PDMS) / glass for precise liquid sampling, based on the electrochemical generation of O2. The device is composed of two chambers separated by a PDMS membrane. In t ...
We have fabricated and characterized a polymethylmethacrylate (PMMA) valveless micropump. The pump consists of two diffuser elements and a polydimethylsiloxane (PDMS) membrane with an integrated composite magnet made of NdFeB magnetic powder. A large-strok ...
The current work examines the effects of model allochtonous (humic substances) and autochtonous (microbial polysac charides) natural organic matter (NOM) on Pb speciation and bioaccumulation. The results demonstrated that polysaccharides, in particular alg ...
This paper reports on polyimide microfluidic devices fabricated by photolithography and a layer transfer lamination technology. The microchannels are sealed by laminating an uncured polyimide film on a partially cured layer and subsequent imidization. Sele ...
From electrochemical measurements at the interface of two immiscible electrolytes, the current at controlled potential is usually a linear function of the ion concentration in the aqueous phase. Surprisingly, a linear relationship between the current and t ...
Patterning of micro- and nanometer scale structures by means of nanostencils (shadow masks) is increasingly being used as a simple, clean and low-cost alternative to photolithography. Currently, large area pattern transfer using nanostencil lithography is ...
