Characterization of PVA-Enzyme Coated Indicator Electrodes GA coated again with PVC-KTpClPB-o-NPOE UV-Vis analysis, variable signal analysis, sensor sensitivity and SEM-EDS

Cell Adhesion to Plasma-Coated PVC

To produce environments suitable for cell culture, thin polymer films were deposited onto commercial PVC plates from radiofrequency acetylene-argon plasmas. The proportion of argon in the plasmas, P(Ar), was varied from 5.3 to 65.8%. The adhesion and growth of Vero cells on the coated surfaces were examined for different incubation times. Cytotoxicity tests were performed using spectroscopic me...

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

Electrochemo-dynamical characterization of polypyrrole actuators coated on gold electrodes.

Polypyrrole coated gold wires were subjected to consecutive square current waves in LiClO4 aqueous solutions using the same constant anodic and cathodic charge. Parallel in situ diameter variations were followed using a laser scan micrometer. The procedure was repeated by changing one experimental variable every time: applied current, electrolyte concentration or working temperature to perform ...

Characterization of QCM sensor surfaces coated with molecularly imprinted nanoparticles.

Molecularly imprinted polymers (MIPs) are gaining great interest as tailor-made recognition materials for the development of biomimetic sensors. Various approaches have been adopted to interface MIPs with different transducers, including the use of pre-made imprinted particles and the in situ preparation of thin polymer layers directly on transducer surfaces. In this work we functionalized quar...

Preparation of Methotrexate loaded PLGA nanoparticles coated with PVA and Poloxamer188

Objective(s): Nanoparticles offer an attractive platform for drug delivery through a wide variety of the body's physiological barriers. Furthermore, modification of nanoparticle surface with moeites such as Poloxamer188 can enhance their accumulation and localization at disease site. In this work, we investigated the physiochemical effect of a scavenger receptor (SR-BI) interac...
