Patent number: 11939625Abstract: A method and a sensor for detecting L-cystine are disclosed. The method is implemented by assembling a sodium 3,3?-dithiodipropane sulfonate (SPS) membrane on a surface of Au membrane layer of an Au electrode and using an extended gate of field effect transistor (FET) and in-situ signal amplification of the FET to detect L-cystine sensitively. The polyanion of the SPS membrane adsorbs and binds a positively charged target L-cystine through electrostatic interaction, thus forming an electric double layer structure to generate a membrane potential identifying a monovalent organic ammonium ion. The sensor includes the FET, wherein a gate-extended gold electrode is arranged on the FET, and the SPS membrane is assembled on the surface of the Au membrane layer of the gate-extended gold electrode. The sensor has an excellent Nernst response to L-cystine.Type: GrantFiled: August 24, 2019Date of Patent: March 26, 2024Assignee: CHANGSHA UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Zhong Cao, Jia Yang, Chen Liu, Zhongliang Xiao, Dan Li, Ling Zhang, Yuyang Zhang, Jiaxin Li

Publication number: 20220065808Abstract: A method for a selective detection of L-tryptophan (L-Trp) using formaldehyde as a medium is disclosed. The method includes preparation of a copper sulfide nanosheets-chitosan/acidified functionalized multi-wall carbon nanotubes (CuS NS-CS/F-MWCNTs) composite material, preparation of a composite film-modified electrode CuS NS-CS/F-MWCNTs/GCE, and a detection of the L-Trp. Since oxidation peaks of L-Trp and L-tyrosine (L-Tyr) overlap and are difficult to separate, the present invention provides a method for a highly selective detection of L-Trp through the Pictet-Spengler reaction of formaldehyde (HCHO) with L-Trp, in which the oxidation peak potential of L-Trp is shifted to 0.82 V and the oxidation peak potential of L-Tyr is 0.63 V, thereby effectively avoiding the interference of L-Tyr. The CuS NS-CS/F-MWCNTs/GCE is applied to detect L-Trp in the formaldehyde medium without any interference from L-Tyr or other amino acids with 50-fold concentrations.Type: ApplicationFiled: August 24, 2020Publication date: March 3, 2022Applicant: CHANGSHA UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Zhong CAO, Junyi HE, Qin ZHU, Chu LIU, Saifei FENG, Huiying HU, Donghong YU
