Therapeutic approach of carbon nanotube: Revolutionize nanomaterial in biomedical and pharmaceutical sector

Carbon nanotubes (CNTs) has emerged as a promising nanomaterial with a wide range of potential applications due to their unique structural, mechanical, electrical, and thermal properties. However, numerous obstacles must be overcome for CNTs to be used successfully, including low solubility, aggregation, and a lack of specialized functions. Diverse techniques have been developed for the manufacture, purification, and functionalization of CNTs in order to overcome these issues. The main aim of this review article is to provide brief knowledge about CNTs and strategies to use this revolutionized nanomaterial in drug delivery. Prepare CNTs cannot be directly used as drug carrier molecules due to the presence of impurities, so purification is an essential aspect of their use. In addition, various functionalization procedures are used frequently for drug conjugation with other benefits, such as reduced toxicity and targeted delivery. Their nano needle structure can penetrate any cell without damaging it with improved efficiency in targeted drug delivery, cancer cell identification, anticancer molecule delivery, antifungal treatment, and transdermal approaches. This nanostructure also has some antimicrobial activity, and conjugation with some antimicrobial agents shows a synergistic response.
