Using polyamines as the initial organic raw material and by applying simple pyrolysis methods, super cationic carbon quantum dots (CQDs) can easily be made. Since polyamines are natural products and the synthesis procedure is green, these polyamine-derived CQDs display low toxicity and high biocompatibility but possess high antibacterial activity. In addition, polyamine-derived CQDs display other unique properties, such as facilitation of wound healing and passage through the tight junction, which make them a very promising bactericide in future clinical applications.

从灰烬中重生：将有机分子转变为抗菌碳量子点

使用多胺作为初始有机原料，并通过应用简单的热解方法，可以轻松制得超阳离子碳量子点（CQD）。由于多胺是天然产物，并且合成过程是绿色的，因此这些多胺衍生的CQD显示出低毒性和高生物相容性，但具有很高的抗菌活性。此外，源自多胺的CQD还具有其他独特的特性，例如促进伤口愈合和通过紧密连接，这使其成为未来临床应用中非常有前途的杀菌剂。
