Poly (threonine) Modified Carbon Composite Electrode as Sensor for Amoxicillin Determination

The poly(threonine) carbon composite sensor was concentrated as a totally special sensor for the assurance Amoxicillin (AM). The behavior of AM at the electrode surface was researched utilizing electrochemical cyclic voltammetry (CV) and field emission scanning electron microscopy (FE-SEM). Electrochemical investigations uncovered that the projected sensor showed a significant benefit, involving high operative surface area, plentiful reactive spots and outstanding electro-catalytic action for the AM oxidation. In the ideal circumstances, the sensor showed a fine linear response towards the oxidation of AM in the concentration range from 0.10-16.0 mu M. The assessed limit of detection and quantification were found to be 0.12 mu M and 0.45 mu M for AM, respectively. This sensor showed a good sensitivity, steadiness, selectivity, and reproducibility, proposed that the prepared sensor was a capable one for the concurrent assurance with dopamine (DA) and superb recuperation and without the impedances of existing together substances.

Automated summary

The poly(threonine) carbon composite sensor showed excellent performance for the detection of Amoxicillin, with high operative surface area, plentiful reactive spots and outstanding electro-catalytic action. The sensor exhibited a fine linear response to the oxidation of Amoxicillin in the concentration range of 0.10-16.0 mu M. It demonstrated good sensitivity, stability, selectivity, and reproducibility, and was capable of concurrent detection of dopamine without interference from co-existing substances.
