Abstract

Surface modification of titanium temporary anchorage device (TAD) plays a crucial role in determining their biological performance. Here, we report a dual-functional coating strategy combining femtosecond laser patterning with layer-by-layer (LBL) assembly of silver nanoparticles (AgNPs)-loaded chitosan/heparin films on TA1 titanium surfaces. Surface characterization via SEM and XPS confirmed successful coating preparation and AgNPs loading. The antibacterial efficacy against E. coli increased with AgNPs concentration, while cytotoxicity studies revealed that high AgNPs concentrations exhibited certain toxicity toward MC3T3-E1 cells. The micro/nanostructures created by laser patterning provided additional storage space for AgNPs, potentially enabling sustained release. This work demonstrates a promising approach for developing multifunctional TAD surfaces with both osteogenic and antibacterial properties.

纳米银涂层在激光图像化钛临时锚定装置上的逐层组装，增强了成骨和抗菌性能

钛临时锚定装置（TAD）的表面改性对其生物性能起着至关重要的作用。在这里，我们报道了一种双功能涂层策略，结合飞秒激光图图化和在TA1钛表面上逐层组装负载银纳米粒子（AgNPs）的壳聚糖/肝素薄膜。通过SEM和XPS进行的表面表征证实了涂层制备和AgNPs负载的成功。AgNPs对大肠杆菌的抑菌效果随AgNPs浓度的增加而增加，而细胞毒性研究表明，高浓度AgNPs对MC3T3-E1细胞具有一定的毒性。激光图图化产生的微/纳米结构为AgNPs提供了额外的存储空间，有可能实现持续释放。这项工作展示了一种开发具有成骨和抗菌性能的多功能TAD表面的有前途的方法。
