In this paper, we report a novel pattern of composite electrocatalysts. PPy/iron-oxalate films exhibit photo-electrochemical
activity. The PPy/B12 composite electrode on stainless steal (SS) support shows high catalytic activity in the electrochemical
reduction of methylviologen. Thin polymer layers filled with magnetite particles can be applicable in magneto-selective electrochemical
reactions. 相似文献
Graft copolymers with a conducting polymer backbone are a promising class of materials for diverse applications including, but not limited to, organic electronics, stimuli‐responsive surfaces, sensors, and biomedical devices. These materials take advantage of the unique electrochemical and optoelectronic properties of conducting polymers, complemented by chemical and/or physical properties of the grafted sidechains. In this Personal Account, we discuss our work in designing functional surfaces based on graft copolymers with a conducting polymer backbone, in the context of broader developments in the field. We review the synthetic approaches available for the rational design of conducting‐polymer‐based graft copolymers, and examine the types of functional surfaces and soluble materials that may be engineered using these techniques.
The development of nanostructured conducting polymers has opened up novel fundamental and applied frontiers. The present article reviews recent works dealing with synthesis, characterization of nanostructured conducting polymers, and their applications related to biosensors. Various synthesis strategies, mechanism and process parameters, along with their characterization techniques are discussed. Some potential areas for biosensor related applications of nanostructured conducting polymers are highlighted, including catalytic biosensors and bioaffinity biosensors. 相似文献
Here, postfunctionalization and bioapplication of a π‐conjugated polymer named 4‐[4H‐dithieno(3,2‐b:2′,3′‐d)pyrrol‐4‐yl]aniline (DTP‐aryl‐NH2) are reported, which is successfully synthesized via electropolymerization onto the glassy carbon electrode. Folic acid (FA) is used to modify the amino functional polymer via N‐(3‐dimethylaminopropyl)‐N′‐ethylcarbodiimide hydrochloride/N‐hydroxysuccinimide chemistry for the further steps. The selective adhesion of folate receptor positive cells on the surface is followed by the electrochemical methods. Cyclic voltammetry and electrochemical impedance spectroscopy have been used to characterize stepwise modification of the electroactive surface. After optimization studies such as scan rate during the polymer deposition, FA amount for the efficient surface targeting, incubation time with the cells etc., analytical characterization is carried out. The surface morphologies at each step are imaged by using fluorescence microscopy.
