Carbon nanotubes (CNTs) have emerged as promising nanomaterials with unique properties that hold great potential in the pharmaceutical field. These cylindrical structures, composed of rolled-up graphene sheets, exhibit exceptional mechanical strength, electrical conductivity, and a high surface area, making them versatile candidates for various applications. In the realm of pharmaceuticals, carbon nanotubes offer novel opportunities for drug delivery systems, diagnostic imaging, and therapeutic interventions. Their hollow structures can be utilized to encapsulate drugs, protecting them from degradation and facilitating controlled release. Furthermore, the high aspect ratio and surface functionalization potential of CNTs enable targeted drug delivery to specific cells or tissues, minimizing off-target effects.
Carbon nanotubes also exhibit excellent biocompatibility and can be engineered to carry diagnostic agents for imaging purposes, aiding in the early detection of diseases. Additionally, their unique electronic properties have led to advancements in biosensor development, offering sensitive and rapid detection of biomolecules. Despite the significant promise, challenges such as biocompatibility, toxicity, and large-scale production need to be addressed to fully harness the potential of carbon nanotubes in the pharmaceutical field. Ongoing research continues to explore and optimize the applications of CNTs, paving the way for innovative solutions in drug delivery and diagnostics.
