Progesterone (P4) is a kind of hormone that can cause neuropathic disturbances in humans when the concentration overpasses a certain degree. In this work, an electrochemical immunosensor capable of detecting P4 sensitively and selectively was developed. Thionine-graphene oxide (Thi-GO) composites with excellent biocompatibility were synthesized and coated to a clear glassy carbon electrode. P4 coating...
In this article, a new method for the determination of triazine herbicides atrazine and simazine in environment aqueous samples was developed. It was based on solid-phase extraction (SPE) using bamboo charcoal as adsorbent and high-performance liquid chromatography-ultraviolet detector (HPLC-UV) for the enrichment and determination of atrazine and simazine at trace level. Related important factors...
Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is a standard analytical tool for protein identification and peptide sequencing. High sensitivity and resolution are two critical parameters for recording good peptide mass fingerprinting (PMF) of low abundance proteins. Here, we report a novel nanodiamond (ND) (normal size 3–10nm) support for MALDI-MS target, over which α-cyano-4-hydrocinnamic...
