A new water-soluble fluororeactand for the optical detection of saccharides is presented. We have combined the functional naphthalimide fluorophore with the well-known ability of boronic acids to bind to the diol moiety of saccharides. The fluororeactand exhibits sensitivity in the mM range, absorbance and emission in the visible spectral range, large Stokes' shift and fluorescence increase in the physiological pH range.
本文介绍了一种用于糖类光学检测的新型水溶性荧光反应物。我们将功能性萘二甲酰亚胺荧光团与众所周知的硼酸与糖类二元醇结合的能力相结合。该荧光内标在毫摩尔范围内具有灵敏度,在可见光谱范围内具有吸光度和发射度,在生理 pH 值范围内具有较大的斯托克斯偏移和荧光增加。
