Tripeptide Assembly Phases on 2D Nanosheets as Artificial Antibodies for Theragnosis of Bacterial Infection Diseases |
초록 |
It is of great interest to design antibody mimics for the detection and inactivation of specific pathogenic bacteria. Herein, transition metal dichalcogenide (TMD) nanosheet interfaces were functionalized with tripeptide assemblies (TMD-TPs). TMD-TPs were characterized by FT-IR, XPS, and ICP, showing the characteristics of both TMDs and peptides. Various tripeptide assemblies were constructed on the TMDs surface, and the resulting TMD-TPs exhibited different bacteria recognition selectivity. TMD-TPs had great selectivity to target bacteria against ten different kinds of bacteria. In addition, TMD-TPs detected the target bacteria at the concentration as low as a single copy from human serum. By using surface shaving and competitive assays, the binding sites of the bacteria were found through thorough experiments and simulations. Finally, TMD-TPs effectively killed the pathogenic bacteria on the skin wounds of infected mice under nIR irradiation, leading to rapid wound healing. |
