Biomass antibacterial carbon dots and preparation method thereof
The invention relates to a biomass antibacterial carbon dot and a preparation method thereof, and the carbon dot is rapidly prepared by a hydrothermal method or an ultrasonic method based on cheap block turmeric, turmeric powder and turmeric in traditional Chinese medicine residues as precursors. The preparation method is simple in process, low in cost and high in benefit, and a reaction object can be recycled as a precursor to be used. The carbon dots prepared by the method have efficient photodynamic performance, can efficiently kill bacteria, and also can efficiently kill fungi..
