Recent Studies from Lanzhou University Add New Data to Endocrine Research

February 7, 2014



By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Endocrine Research. According to news reporting originating in Lanzhou, People's Republic of China, by NewsRx journalists, research stated, "A facile and green method was developed to synthesize the graphene-carbon nanotubes (Gr-CNTs) nanocomposite with a sandwich lamination structure. Pt nanoparticles were loaded on the as-synthesized Gr-CNTs nanocomposite to prepare an electrochemical sensor for determining bisphenol A (BPA) in thermal printing paper."

The news reporters obtained a quote from the research from Lanzhou University, "The electrochemical behavior of BPA on the Pt/Gr-CNTs nanocomposite was investigated by cyclic voltammetry (CV) and chronocoulometry (CC). The direct determination of BPA was accomplished by using differential pulse voltammetry (DPV) under optimized conditions. The oxidation peak current was proportional to the BPA concentration in the range from 6.0 x 10(-8) to 1.0 x 10(-5) M and 1.0 x 10(-5) to 8.0 x 10(-5) M with a correlation coefficient of 0.987 and 0.998, respectively. The detection limit was 4.2 x 10(-8) M (S/N=3). The fabricated electrode showed good reproducibility, stability and selectivity."

According to the news reporters, the research concluded: "The proposed method was successfully applied to determine BPA in thermal printing papers samples and the results were satisfactory."
