Carbon nanotubes possess unique electrical and mechanical properties that enable their use in various biomedical applications. Their hollow structure and high surface area make them suitable for drug delivery systems and as carriers for antigens in immunotherapy. Additionally, their conductivity and sensitivity allow for their integration into biochemical sensors for detecting specific molecules. While research is ongoing into their biocompatibility, concerns exist regarding their long-term biodegradability and potential accumulation in the body, though some studies suggest potential degradation pathways.
