چکیده

We demonstrated a site-specific fabrication of conducting polymer micropatterns by a novel electrochemical micropatterning technology, which utilizes a hydrodynamically focused laminar stream as a dynamic template. The resulting micropatterns in a microfluidic device is a ready-to-use sensor capable of detecting microliter amounts of organic solvent vapors. By employing two different sensing elements (polypyrrole (Ppy) and COOH-Ppy), the collective sensing responses are informative enough to identify a wide range of organic vapors.

An aptasensor based on electrosynthesized conducting polymers, Cu2O–carbon dots and biosynthesized gold nanoparticles, for monitoring carcinoembryonic antigen

Current work proposes an inimitable composite, with great electrical conductivity and quite enhanced surface area, (including conducting polymers (poly (cathechol)), Cu2O–carbon dots and green synthesized gold nanoparticles) for detecting acute carcinoembryonic antigen. At current work, the electropolymerization was offered instead of enzyme-catalyzed polymerization of poly (catechol). <b...

Electrochemical fabrication of polypyrrole nanofibers and their characterization

Polypyrrole (PPy) nanofibers have been fabricated on glassy carbon electrode (GCE) usingelectrochemical technique. Electropolymerization of pyrrole (Py) for the fabrication of PPy nanofiberswas occurred on GCE by applying a fixed potential of about 0.85 V for 120 sec in a mild basic solutioncontaining sodium carbonate and sodium perchlorate. In the mild basic media, the monomer, Py, isoxidized ...
