An Electrochemical Sensor Based on Molecularly Imprinted Polymer for Methyl Paraben Recognition and Detection

Conductive Molecularly Imprinted Polymers (cMIPs): Rising and Versatile Key Elements in Chemical Sensing

“…Phenylene diamine is a less frequent monomer. Soysal demonstrated an electrochemical sensor based on electropolymerized p-phenylenediamine MIP to detect methyl paraben [63]. Ayankojo et al electropolymerized erythromycin-imprinted poly-phenylenediamine onto screen-printed electrodes.…”

“…Melamine has been used as a fake protein source in infant formula and pet food in China. It is connected to acute renal failure in animals General overview of the different application areas of cMIP-based sensors, cited from [32][33][34][35]37,39,40,42,43,45,47,48,[54][55][56]58,63,66,67,[76][77][78]88,[91][92][93][95][96][97]101,105,107,116,119,120,122,124,[127][128][129]134,135,137,139,140].…”

“…Not only drugs, but also other health relevant molecules, such as endocrine disrupting compounds, can be assessed. For example, 4-hydroxybenzoic acid esters, which are frequently used as antimicrobial additives in cosmetics and pharmaceutical products, were successfully measured in real samples with a novel sensor [63] (Table 1).…”

Electrochemical sensors for the safety and quality control of cosmetics: An overview of achievements and challenges

“…A few electroanalytical methods have been reported for the determination of parabens in cosmetics [48,[56][57][58][59][60][61]. Electrochemical quantification of MP was successfully performed using sensors based on: GCE modified with graphene oxide and ruthenium nanoparticles [56], MWCNTs coupled with Nafion-modified GCE [60], gold electrodes modified with Layer-by-Layer (LbL) films of magnetite nanoparticles and polypyrrole [57], pencil graphite electrode modified by molecularly imprinted polymer [61].…”
