TiO₂ nanotubes guided Pt nanorods growth via atomic layer deposition for mild photothermal antibacterial activity and enhanced fibroblast response.

ABSTRACT:

Introduction

Soft tissue integration (STI) and antibacterial capability are critical for the long-term success of dental implants. However, achieving both simultaneously remains a major clinical challenge. This study aims to address this challenge by developing a novel surface modification strategy that combines both robust antibacterial properties and favorable soft tissue responses for dental implants.

Methods

A novel nanostructured coating was fabricated by embedding hollow platinum nanorods (PtNRs) into titania nanotubes (TNTs) using atomic layer deposition (ALD). The resulting PtNR@TNT platform was characterized to confirm its stable architecture and dual biofunctionality. Structural characterizations were conducted to verify that PtNRs were uniformly deposited along th
