چکیده
This paper presents the development of a cheap and rapid electrochemical sensor for ascorbic acid detection. In particular, graphite ink working electrode screen-printed cells was covered by film elecrosynthesized molecularly imprinted polypyrrole (e-MIP); differential pulse voltammetry (DPV) selected method analyte The molecules were successfully entrapped in film, creating recognition sites. best results obtained after overoxidation performing measurements phosphate buffer solution 0.05 M/KCl 0.1 M at pH 7.5. A comparison with bare not-imprinted polypyrrole-modified electrodes showed that e-MIP-based had highest selectivity reproducibility. developed applied to assess farmaceutical products, obtaining values not significantly different from declared content.

متن کاملMolecularly Imprinted Polymer Nanoparticles for Formaldehyde Sensing with QCM
Herein, we report on molecularly imprinted polymers (MIPs) for detecting formaldehyde vapors in air streams. A copolymer thin film consisting of styrene, methacrylic acid, and ethylene glycol dimethacrylate on quartz crystal microbalance (QCM) yielded a detection limit of 500 ppb formaldehyde in dry air. Surprisingly, these MIPs showed specific behavior when tested against a range of volatile o...
