Abstract

Cysteine (Cys) is a crucial biological thiol that facilitates broad range of biological circumstances and health conditions. Especially the aberrant Cys level in human serum is an independent risk factor for cardiovascular diseases. What more, Cys metabolism (Cys to SO2) is typically connected with illnesses such as lung cancer, and are recognized as biomarker. Herein, an innovative multifunctional fluorescent probe was rudimentarily designed and utilized, not only for realizing real-time visualization of the metabolism of Cys to SO2 in tumors through two self-sufficient channels without spectral cross-interference, but also for sensitive, real-time, on-site, and quantitative visual recognition of Cys in human serum through 3D-printed smartphone sensing platform. In addition, the probe’s unique response to Cys/HSO3 in distinct spectral behaviors, which have been characterized theoretically using UV–Vis, fluorescence, DFT calculations, and 1H NMR. More importantly, the methodology reported herein enables an available pathway for real-time/on-site and visual determination of Cys in human serum and is expected to extend the use of potential cardiovascular disease biomarker studies for initial monitoring and clinical diagnosis.

基于多功能荧光探针的3d打印便携式智能手机平台,深入了解生命系统中Cys及其衍生物的代谢
半胱氨酸(Cys)是一种重要的生物硫醇,促进了广泛的生物环境和健康状况。特别是人血清中异常的胱氨酸水平是心血管疾病的独立危险因素。此外,Cys代谢(Cys to SO2)通常与肺癌等疾病有关,被认为是一种生物标志物。本文初步设计并利用了一种新型多功能荧光探针,不仅可以实现肿瘤中Cys对SO2代谢的实时可视化,而且可以通过3d打印智能手机传感平台实现对人血清中Cys的灵敏、实时、现场、定量的视觉识别。此外,该探针对Cys/HSO3 -具有独特的光谱行为响应,这些光谱行为已通过UV-Vis,荧光,DFT计算和1H NMR进行了理论表征。更重要的是,本文报道的方法为实时/现场和视觉检测人血清中的Cys提供了可行的途径,并有望扩大潜在心血管疾病生物标志物研究在初始监测和临床诊断中的应用。

期刊介绍: Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (SAA) is an interdisciplinary journal which spans from basic to applied aspects of optical spectroscopy in chemistry, medicine, biology, and materials science. The journal publishes original scientific papers that feature high-quality spectroscopic data and analysis. From the broad range of optical spectroscopies, the emphasis is on electronic, vibrational or rotational spectra of molecules, rather than on spectroscopy based on magnetic moments. Criteria for publication in SAA are novelty, uniqueness, and outstanding quality. Routine applications of spectroscopic techniques and computational methods are not appropriate. Topics of particular interest of Spectrochimica Acta Part A include, but are not limited to: Spectroscopy and dynamics of bioanalytical, biomedical, environmental, and atmospheric sciences, Novel experimental techniques or instrumentation for molecular spectroscopy, Novel theoretical and computational methods, Novel applications in photochemistry and photobiology, Novel interpretational approaches as well as advances in data analysis based on electronic or vibrational spectroscopy.
