Development of an Electro-Responsive Sorafenib-Loaded Polypyrrole Coating-Modified Nickel–Titanium Alloy for Tumor Ablation Therapy
Nickel–titanium (NiTi) stents have been widely used for the palliative management of portal vein tumor thrombosis (PVTT) due to their excellent mechanical strength and biocompatibility. However, conventional NiTi implants are therapeutically passive and lack intrinsic antitumor activity, rendering them vulnerable to tumor ingrowth and subsequent restenosis. Electrical stimulation-mediated ablation offers a controllable physical strategy for local tumor clearance; however, the native TiO2 passivation layer on the Ni …
