Navigating the Nanoscale: Advancements in Carbon Nanotube-Based Drug Delivery Systems

Abstract

Carbon nanotubes (CNTs) are gaining attention as exciting options for drug delivery nanocarriers, thanks to their unique physicochemical properties. These include a high surface area, customizable functionalization, and excellent biocompatibility. Their knack for crossing biological barriers, zeroing in on specific cells, and enabling controlled drug release positions them as strong candidates for enhancing therapeutic effectiveness while minimizing systemic toxicity. In this review, we’ll explore the latest developments in CNT-based drug delivery systems, diving into functionalization techniques, targeted delivery methods, and their applications in treating cancer, neurological disorders, and fighting infections. While carbon nanotubes (CNTs) have incredible potential, there are still hurdles to overcome, like cytotoxicity, biodegradability, and regulatory challenges, before they can be used in clinical settings. The combination of CNTs with artificial intelligence and personalized medicine techniques offers exciting possibilities for precise drug delivery. Future studies should prioritize safety and improving biocompatibility to ensure these technologies can be widely adopted in healthcare. By exploring the unique nanoscale properties of carbon nanotubes, researchers can create innovative drug delivery systems that significantly improve patient care and treatment outcomes.
