注意

室温下,在水中的浓度超出约 70% 时每月易形成 1 到 2% 的含硫苷,在酸性或碱性条件下又水解为原始的游离化合物。浓度为 70% 的溶液在空气中易氧化,密封后在室温下可保持稳定。巯基乙酸盐在储存时纯度可能降低。除去空气并不能显著提高稳定性。

The aim of this study was to investigate the influence of molar mass of thiolated polymers (thiomers) on their in situ gelling properties. Chitosan-thioglycolic acid (chitosan-TGA) and pectin-cysteine (pectin-Cys) of increasing molar mass were chosen to produce in situ gels

Fluorescent carbon dots (CDs) were solvothermaly synthesized in water-glycol medium by using glucose as carbon source and then modified with polyethyleneimine (PEI) for the first time to improve fluorescence quality. The as-prepared CDs were monodispersed sphere particles with a diameter

We validated novel bimodal iron oxide particles as substitute of ferumoxides for efficient labeling of human neural stem cells (NSCs). The dextrane-coated FeraTrack Direct (FTD)-Vio particles have additional far-red fluorophores for microscopic cell analysis. MR relaxometry, spectrophotometric iron determination and

A novel subclass B3 metallo-β-lactamase (MBL), SMB-1, recently identified from a Serratia marcescens clinical isolate, showed a higher hydrolytic activity against a wide range of β-lactams than did the other subclass B3 MBLs, i.e., BJP-1 and FEZ-1, from environmental bacteria.

A novel fluorescent probe for Cu(2+) determination based on the fluorescence quenching of glyphosate (Glyp)-functionalized quantum dots (QDs) was firstly reported. Glyp had been used to modify the surface of QDs to form Glyp-functionalized QDs following the capping of thioglycolic
