Carbon Nanotubes: Applications in Biomedical Fields

Carbon nanotubes (CNTs) are cylindrical, one-dimensional allotropes of carbon with a high length-to-diameter ratio, lightweight, and high chemical and thermal stability. CNTs have various types and due to their unique surface properties can be functionalized with different materials. This study aimed to review the various biomedical applications of CNTs. CNT-based nanomaterials can be used for different biomedical applications, such as tissue engineering and regeneration (as scaffolds), imaging and diagnostics (MRI, CT scan and ultrasound imaging), gene delivery, targeted drug delivery to tumors and image-guided cancer treatment, biomolecules detection, and neuroscience applications. Besides, in the manufacture of medical devices such as urinary catheters, CNT-based nanomaterials with antimicrobial properties can be used to reduce the risk of infection. It should be noted that due to the toxicity of CNTs, they are functionalized with various functional groups to provide biocompatibility for biomedical applications. As a conclusion, nanomaterials based on CNTs, due to their desirable physicochemical properties, have great and promising efficacy in various biomedical fields to improve human health.
