Abstract

In recent years, MXenes have drawn extensive interest in many fields due to their unique features. Herein, 2D MXene Ti2CTx nanosheets (NSs) are successfully fabricated which not only display highly photothermal efficiency, but exhibit excellent biocompatibility and impressive biosafety in the ophthalmic environment. Moreover, the as-fabricated Ti2CTx NSs present superior antibacterial activity against two common pathogenic bacteria (Escherichia coli and Streptococcus mutans), which can be further enhanced under NIR light due to excellent photothermal conversion of Ti2CTx NSs. Moreover, the excellent stability for the Ti2CTx NSs holds great promises in the practical ophthalmic applications.
