“…However, CAP has serious toxic side effects which can cause some diseases, such as anemia, leucopenia and aplastic anemia [2]. Besides, long-term intake of a trace of CAP can make the Salmonella, Escherichia coli drug-resistant [3], as well as cause the imbalance of body's normal flora.…”

“…Meanwhile, it is also generally applied for food‐producing animal veterinary medicine, domestic poultry, and aqua‐agriculture farming . However, long‐term intake of a trace of chloramphenicol can make anemia, leucopenia, agranulocytosis and aplastic anemia . Hence, the detection of chloramphenicol has been employed in various detection strategies including chromatography tandem mass spectrometry , fluorimetry , colorimetry and chemiluminescence .…”

In this work, a novel redox capacitor was designed for signal amplification in electrochemical detection. It was fabricated by co‐electrodeposition of a conducting polymer, sulfonated polyaniline (SPAN) and chitosan on a glass carbon electrode, and its function was evaluated for being a localized source to transfer electron between FcCOOH (Fc) and Ru(NH3)6Cl3 in solution via redox cycling. Furthermore, the electrochemical detection of chloramphenicol, a broad‐spectrum antibiotic was performed using the redox capacitor in the presence of Fc. A significant amplification in cathodic current response of chloramphenicol was obtained through a continuous redox‐cycling reaction. The performance of the amplifying signal responded linearly to chloramphenicol in a concentration range of 0.05 to 50.0 μmol L−1 with a low detection limit of 0.01 μmol L−1. The proposed approach exhibited good reproducibility and stability, and could be used for detection of chloramphenicol in eye drops by standard addition method with the recoveries from 96.5 % to 103.0 %.

“…Until now, some reports found in the literature describe the use of MIP as potentiometric sensing materials. [41][42][43][44][45][46][47][48][49][50].…”

“…Potentiometry is included here and offers the advantages of not requiring the template to be extracted from the membrane and the species to be diffused through the membrane [40]. Despite these advantages, most research work within this �led has been conducted only most recently [41][42][43][44][45][46][47][48][49][50]. erefore, the present work tries to (i) develop MIP materials designed for LMG instead MG, because LMG is the major �sh metabolite that may be found in waters, (ii) search for an alternative functional monomer, by replacing the traditional MAA by acrylamido-2-methyl-1-propanesulfonic acid (AMPSA), (iii) and open new horizons on the use of these materials, by applying these in biosensing development, something never done before for LMG nor MG. e sensory materials were thus synthesized with methacrylic acid (MAA) and acrylamido-2-methyl-1-propanesulfonic acid (AMPSA) functional monomers, cross-linked by ethylene glycol dimethacrylic acid (EGDMA) within the template molecule.…”

A new biomimetic sensor for leucomalachite green host-guest interactions and potentiometric transduction is presented. e arti�cial host was imprinted in methacrylic acid or acrylamido-2-methyl-1-propanesulfonic acid-based polymers. Molecularly imprinted particles were dispersed in 2-nitrophenyloctyl ether and trapped in poly(vinyl chloride). e potentiometric sensors exhibited a near-Nernstian response in steady state evaluations, with slopes and detection limits ranging from 45.8 to 81.2 mV decade −1 and 0.28 to 1.01 g mL −1 , respectively. ey were independent from the pH of test solutions within 3 to 5. Good selectivity was observed towards drugs that may contaminate water near �sh cultures, such as oxycycline, doxycycline, enro�oxacin, trimethoprim, creatinine, chloramphenicol, and dopamine. e sensors were successfully applied to �eld monitoring of leucomalachite green in river samples. e method offered the advantages of simplicity, accuracy, applicability to colored and turbid samples, and automation feasibility.
