Preparation method of fluorescent carbon dots modified by organosilane

The invention discloses a preparation method of fluorescent carbon dots modified by organosilane. The preparation method is a method of preparing carbon dots through a hydrothermal process. Soybean milk powder is used as a carbon source, so that environment friendliness, safety and low production cost are realized; the preparation method is simple and can realize mass production. The carbon dots prepared by the method are high in fluorescent intensity and yield, excellent in photostability and less prone to quenching and can be used in the field of molecular fluorescent detection, biological fluorescent imaging and signal sensing. 本发明公开了种有机硅烷修饰的荧光碳点的制备方法。本发明为水热法制备碳点的方法，所用的碳源为豆奶粉；绿色安全，生产成本低，且制备方法简单，可以实现批量化生产。制得的碳点荧光强度好，产率高，光稳定性优秀，不易淬灭，可用分子荧光检测、生物荧光成像、信号传感等领域。
