Abstract
The presence of Bisphenol A (BPA) as a component in products for human use represents a risk to public health because it is an endocrine disruptor. For this reason, it is necessary to detect the presence of this compound in an easy, fast, and economical way. To aid in the detection of this substance, this work presents an unmodified screen-printed electrode-based sensor for electrochemical detection, simple, low-cost and affordable to detect BPA. The electrochemical detection is based on methylene blue as a redox probe, a sample analysis is carried out using three different electrochemical techniques, cyclic voltammetry, linear-sweep voltammetry and square-wave voltammetry. The results show the sensor’s ability to detect and quantify BPA. In this sense, our unmodified screen-printed electrode-based sensor is an attractive, cost-effective and low-cost tool to determine the presence of BPA.
