Abstract Implant‐associated infections are the most critical threat to orthopedic surgeries. Various surface‐modification strategies developed impart antibacterial properties and osteogenesis‐promoting abilities surfaces of implants. Nevertheless, a straightforward strategy for constructing functional, stable, bioactive implant surface remains challenging. Here, facile one‐step surface‐bioactivation method is that enhances both anti‐infection capabilities osteointegration performance This approach utilized kind coating integrates agents components directly onto titanium The cationic agent bone‐adhesion‐enhancing peptide covalently attached via Michael reaction poly (tannic acid) (PTA) create dual‐functional implants (Ti‐PR). Ti‐PR effectively eliminated more than 99% common pathogenic bacteria significantly enhanced osteogenic differentiation bone marrow mesenchymal stem cells (BMSCs) in vitro. cell‐bacteria competitive culture assay on confirms its bactericidal cell proliferation‐promoting properties. Additionally, RNA‐Seq analysis indicated PI3K/Akt pathways played crucial role enhancing BMSCs. superior osteogenesis performances confirmed an implant‐related infection model vivo. study provided efficient design production innovative multifunctional

N-Type Silver Selenide Thermoelectric Cotton Thread for Antibacterial and Versatile Textile Electronics

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: March 26, 2025

Thermoelectric textiles have garnered significant attention in energy harvesting and temperature sensing due to their comfort reliable long-term power generation capabilities. However, existing thermoelectric rarely realize antibacterial, high output performance, capabilities simultaneously. Here, we present a facile scalable method for fabricating n-type silver selenide (Ag2Se) cotton threads with exceptional output, advanced The Ag-Ag2Se segmented structures are prepared using the selenization method. Subsequently, textile consisting of 50 pairs p-n legs is fabricated, which can generate density 500 μW m-2 at difference 30 K, it provide an voltage 24.7 mV when worn on arm room temperature. textile-based sensor exhibits detection (0.7 K) response time (2.49 s). Integrating Ag2Se onto enables utilization multipixel touchpads writing communication. Additionally, these sensors be incorporated into gloves accurately detect surrounding objects' temperatures. This thread not only facilitates but also establishes solid foundation widespread application multifunctional electronics.
