In modern society, the use of cosmetics has increased extensively; unfortunately, so-called several toxic metal salts are present as the colorant or filler in cosmetics. The ferrous ion (Fe2+) is one of the metal ions used in cosmetics as a colorant. Ferrous ion (Fe2+) is a vital component in live cells. Considering the adverse effect of high doses of ferrous ions in cosmetics and live cells, we developed a turn-on fluorescent probe PFe(II) for quantitative estimation of ferrous ion (Fe2+) in cosmetics and monitoring of labile ferrous (Fe2+) ion in live cells. The fluorescent probe PFe(II) showed a visual color change from colorless to orange in the presence of ferrous ion (Fe2+) in the cosmetics. We observed that UV-absorption increased at 390 nm upon incubation with ferrous ion (Fe2+). The probe PFe(II) has provided quantitative information on ferrous ion (Fe2+) in various cosmetics, kajol, lip balm, face foundation, mascara, eyeliner, lipliner, face makeup, sindoor, lipstick, nail polish in ppm level through the fluorescence signaling at 460 nm.The probe PFe(II) provided information on labile Fe2+ ion pool via a fluorescence imaging. It is a new addition to the diagnostic inventory for detecting ferrous ion in live cells and cosmetics.

用于化妆品和活细胞中亚铁(Fe2 +)离子检测的高化学选择性开启荧光探针。

在现代社会中,化妆品的使用已广泛增加。不幸的是,所谓的几种有毒金属盐作为化妆品中的着色剂或填充剂存在。亚铁离子(Fe 2+)是化妆品中用作着色剂的金属离子之一。亚铁离子(Fe 2+)是活细胞中的重要成分。考虑到高剂量亚铁离子对化妆品和活细胞的不利影响,我们开发了一种开启式荧光探针P Fe(II用于定量估计化妆品中亚铁离子(Fe 2+)和监测不稳定的亚铁(Fe 2 +)活细胞中的离子。荧光探针P Fe(II 在化妆品中存在亚铁离子(Fe 2+)时,显示出从无色到橙色的视觉颜色变化。我们观察到,与亚铁离子(Fe 2+)孵育后,紫外线吸收在390 nm处增加。探针P Fe(II 提供了ppm级以下各种化妆品,kajol,润唇膏,面部粉底,睫毛膏,眼线笔,lipliner,脸部化妆品,sindoor,口红和指甲油中的亚铁离子(Fe 2+)的定量信息。460 nm处的荧光信号。探针P Fe(II提供了有关不稳定Fe 2+的信息离子池通过荧光成像。它是用于诊断活细胞和化妆品中亚铁离子的诊断清单中的新增功能。
