Electrosynthesis of high-density polythiophene nanotube arrays and their application for sensing of riboflavin

摘要: Abstract High-density arrays of polythiophene nanotubes were successfully prepared through electrochemical polymerization the monomer in pores porous anodic alumina (PAA) template. The resultant polymeric tubular structures identified by field-emission scanning electron microscopy with a diameter order ca 100 nm and length up to several micrometers. Different characterizations, including SEM, TEM EDS, employed prove that conducting synthesized this facile method. for proposing new sensor Riboflavin (RF). Under optimal conditions, suggested could be used determination RF ranging from 0.01 65 μM low detection limit 3 nM. possessed accurate rapid response good sensitivity, stability repeatability. Furthermore it showed an average recovery 97% human plasma.
