The invention relates to a method for preparing an antibacterial agent based on MXene quantum dots and testing its antibacterial activity, which relates to the field of antibacterial applications. The invention adopts the combination of electrochemical method and photochemical method to prepare carboxylated MQDs, firstly prepares MQDs by electrochemical method, and polymerizes Ti3AlC2 into Ti3C2 quantum dots in electrolyte solution ; then prepares carboxyl group by photochemical method Through the reaction of hydroxyl radicals generated by H 2 O 2 with MQDs under UV irradiation, MQDs with a large number of carboxyl functional groups on the surface were finally obtained. Ti3C2Tx MXene quantum dots ( MQDs ) derived from 2D MXene materials not only retain the excellent electrical conductivity, temperature and chemical stability of pristine MXene layered materials, but also exhibit good water solubility, biological phase Capacitance and low toxicity make Ti 3 C 2 T x MXene quantum dots have great application potential in the field of antibacterial. |
