Rapid SERS-based recognition of cell secretome on the folic acid-functionalized gold gratings
Published in Analytical and Bioanalytical Chemistry
Nowadays, functionalization of the plasmon-supported nanostructured surface is considered as a powerful tool for tumour cell recognition. In this study, the SERS on a surface plasmon polariton-supported gold grating functionalized with folic acid was used to demonstrate an unpretentious recognition of melanoma-associated fibroblasts. Using cultivat...
Simultaneous determination of metabolic and elemental markers in methamphetamine-induced hepatic injury to rats using LC...

Methamphetamine (METH) is one of the most highly addictive illicit drugs abused all over the world. Much evidence indicates that METH abuse leads to major toxicity, medical consequences, and even severe public health consequences. Existing studies usually focus on the pathomechanism of METH-induced toxicity; therefore, data on metabolites and eleme...
Identification of the lipid-lowering component of triterpenes from Alismatis rhizoma based on the MRM-based characterist...
Published in Analytical and Bioanalytical Chemistry
It has been demonstrated that triterpenes in Alismatis rhizoma (Zexie in Chinese, ZX) contributed to the lipid-lowering effect on high-fat diet-induced hyperlipidemia. Alisol B 23-acetate, one of the abundant triterpenes in ZX, was used as the marker of quality control for ZX in Chinese Pharmacopoeia, while it could not reflect the lipid-lowering e...

A new and improved method was developed for the determination and quantification of four “free” thyroid hormones (i.e. 3,5-diiodothyronine (T2), 3,3′,5-triiodothyronine (T3), 3,3′,5′-triiodothyrone (rT3) and 3,5,3′,5′-tetraiodothyronine (T4)) in human serum by low- and high-resolution liquid chromatography-mass spectrometry (LC-MS). Several sample ...
Parallel reaction monitoring with multiplex immunoprecipitation of N-glycoproteins in human serum for detection of hepat...
Published in Analytical and Bioanalytical Chemistry
The N-glycosylation of proteins is one of the most important post-translational modifications relevant to various biological functions. The identification and quantification of N-glycoproteins in liquid chromatography–mass spectrometry (LC-MS) is challenging because of their low analytical sensitivity and selectivity. This is due to their microhete...
A facile and label-free ratiometric optical sensor for selective detection of norepinephrine by combining second-order s...
Published in Analytical and Bioanalytical Chemistry
In this work, a facile and label-free ratiometric sensor is constructed for selective determination of norepinephrine (NE) by coupling second-order scattering (SOS) and fluorescence, two different and independent optical signals. Herein, polyethyleneimine (PEI) dilute solution medium shows an intensive SOS signal without any fluorescence response. ...
