For biocompatible electrode applications, electrically conductive films such as titanium nitride (TiN) are needed, which do not require additional protective and adhesive layers. TiN thin films, known for their excellent flexibility electrical conductivity, actively researched applied in tribology electronics industries electrodes. were prepared using dual magnetron sputtering with varying DC power. Several tribological properties evaluated improved application device The sputtered exhibited hardness, elastic modulus, strength, smooth surface, hydrophilicity. Increasing the power enhanced a slight increase surface roughness. When applying electrodes to an organic thin-film transistor (OTFT) biosensor, successful achieved. In addition, contribute improving lifespan of OTFTs by enhancing physical chemical stability.

Titanium (Ti) implants are widely used for tooth replacement due to their exceptional mechanical properties and high biocompatibility. However, inherently inert surface limits osteogenic potential makes them prone bacterial colonization, increasing the risk of biofilm formation implant-related infections. To address these limitations, modification Ti is essential. This study aimed enhance by coating it with polydopamine (PDA) further doping copper calcium ions. TPDA was prepared subsequently fabricate TPDA@Cu TPDA@CuCa samples. Material characterization confirmed that exhibited excellent wettability biocompatibility, Cu2 + Ca2+ being continuously stably released in liquid environments. Additionally, significantly improved protein adsorption, facilitating favorable cellular interactions. In vitro experiments demonstrated strong antimicrobial activity against Escherichia coli Staphylococcus aureus, enhanced osteoblast adhesion, mineralization, upregulated gene expression. bifunctional strategy offers a promising approach enhancing both antibacterial implants.
