Highly Conductive and Stretchable Photothermal CuSe Fiber for Wearable Electronics and Implantable Drug Release Systems (Adv. Funct. Mater. 42/2026)

Key Points

• The study aims to develop a stretchable and conductive fiber that releases drugs when triggered by near-infrared (NIR) light.
• Developed a CuSe-based photothermal fiber for wearable and implantable applications.
• Investigated the ability of the fiber to generate heat upon exposure to NIR laser irradiation.
• Assessed the drug release efficiency from the fiber in response to NIR triggering.
• The photothermal fiber effectively released therapeutic drugs upon NIR laser exposure.
• Therapeutic effects were enhanced, promoting disease treatment outcomes.
• The fiber maintained its conductivity and stretchability during drug release.
