Abstract
A novel biosensor for the determination of Bisphenol-A has been developed in this study. For this purpose, a carbon paste electrode modified with poly(amidoamine)-salicylidenimine platinum(II) (PAMAM-Sal-Pt(II)) and the tyrosinase enzyme was prepared. BPA determination was based on the electrochemical reduction of an enzymatically produced quinone compound at –0.15 V. Optimum working conditions for the prepared biosensor were investigated. The linear working range and detection limit were found to be 0.01–1.0 μM and 1 nM, respectively. The optimum pH value and working temperature were defined as 7.0 and 40 ℃, respectively. The reproducibility of the biosensor is very good. It was found that phenol, nitrophenol, urea, potassium nitrate, hexane, acetonitrile, and ethyl acetate do not interfere with the BPA determination. The prepared biosensor was used for the first time in dentistry for the determination of BPA in a resin-based composite material used as a bracket adhesive in orthodontics.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
