Latest Patents

Xiaohui Gao holds a patent for a method titled "Method for preparing nanocomposite and label-free aptamer electrochemical sensor of gamma-interferon based on the nanocomposite." This invention describes a technique for creating a label-free aptamer electrochemical sensor that utilizes a dendrimer/gold nanoparticle/molybdenum disulfide nanocomposite. The process involves drip-coating the nanocomposite onto an electrode surface to create a modified electrode. The terminal sulfhydryl group of a gamma-interferon aptamer chain is then connected to the gold nanoparticle via an Au–S bond, resulting in a nanocomposite-aptamer modified electrode. When gamma-interferon is present, it binds specifically to the aptamer chain, leading to a structural change that enhances the redox signal of methylene blue in the electrolyte. This innovation establishes a linear relationship between the current intensity of the methylene blue oxidation peak and the concentration of gamma-interferon, thereby constructing an effective label-free electrochemical sensor.
