Lanzhou University successfully develops flexible and biodegradable supercapacitor implants 2

The cytotoxicity of the materials used in the device was evaluated using the MTT colorimetric method, confirming that the MoOx micro-nano sheets prepared by electrochemical oxidation and the Alg-Na electrolyte exhibit high biocompatibility. After encapsulation, the device can function effectively for 30 days in a simulated body fluid environment (37°C, 0.1 mM PBS solution) and will completely degrade upon task completion. When implanted subcutaneously on the back of SD rats for six months, the device was fully absorbed through metabolism without observing neutrophils or significant inflammation during the process. diode

Compared to traditional supercapacitors, this supercapacitor implant offers the following advantages:

1. Flexibility: Due to the use of flexible polymer materials as the substrate, this supercapacitor implant exhibits excellent flexibility, enabling it to adapt to various complex implantation environments and reducing patient discomfort and pain.

2. Biodegradable: The biodegradable polymer material used by the research team can undergo degradation reactions in the body, ultimately breaking down into non-toxic and harmless substances without causing any harm to human health.diode

3. High Performance: The modified nano-carbon material exhibits excellent conductivity and capacitance, enabling high energy density and power density to meet the demands of implants in various application scenarios.

4. Environmental Protection: Due to the use of biodegradable materials, this supercapacitor implant does not generate any harmful substances during operation, posing no environmental pollution.

The successful development of this research achievement holds significant importance for advancing the progress of flexible electronic devices and biodegradable materials. This flexible, biodegradable supercapacitor implant has the potential to be applied in the medical field, such as implantable medical devices and dissolvable drug delivery systems, offering patients safer and more effective treatment solutions. Meanwhile, the research also provides new insights and approaches for exploring more environmentally friendly and sustainable electronic device materials.diode
