(3-Aminopropyl)triethoxysilane → 2-(6-Hydroxy-3-oxo-3H-xanthen-9-yl)benzoic acid

Participants

Reaction Steps

50 μl APS (γ-amino propyltriethoxyl silane) and 1 ml FITC (fluorescein isothiocyanate, 1 mg/ml ethanol solution) are added into a 4 ml absolute ethyl ethanol under obturation condition to react for 12 hours, so as to obtain a precursor solution upon coupling of fluoresceine and silane coupling agent. The method for preparing the precursor solution is common knowledge in prior art. 3.65 ml ethanol/water mixture (ratio of ethanol to water is 8), 1.2 ml ethanol and 100
