The invention provides a specific anti-staphylococcus nitrogen-doped carbon quantum dot and a preparation method thereof. Glucose and diethylenetriamine are used as reaction substrates to synthesize the specific anti-staphylococcus nitrogen-doped carbon quantum dot through a one-step method. The preparation process is simple, the reaction substrate is cheap, the synthesis reaction is easy, and the obtained nitrogen-doped carbon quantum dot has specific anti-staphylococcus activity and can be used for treating wound surfaces infected by staphylococcus (including staphylococcus aureus, staphylococcus epidermidis and methicillin-resistant staphylococcus aureus (MRSA)). 本发明提供的是一种特异性抗葡萄球菌的氮掺杂碳量子点及其制备方法，以葡萄糖和二乙烯三胺为反应底物通过"一步法"合成具有特异性抗葡萄球菌的氮掺杂碳量子点。本发明制备工艺简单，反应底物廉价，合成反应容易，且所得氮掺杂碳量子点具有特异性抗葡萄球菌活性，可以用于葡萄球菌（包括金黄色葡萄球菌、表皮葡萄球菌和耐甲氧西林金黄色葡萄球菌（MRSA））感染创面的治疗。
