Recent days, there have been notable advancements in the field of nanotechnology for various applications. Carbon nanotubes (CNTs) are materials originating from graphite sheets, these graphite layers resemble an indestructible hexagonal mesh structure that is constantly rolled up, with carbon molecules appearing at the apexes of the hexagonal structures. The single-walled carbon nanotubes, double-walled carbon nanotubes, and multi-walled carbon nanotubesare distinguished by the number of carbon layers they contain. The commonly used techniques for creation of CNTs is chemical vapor deposition, electric arc deposition, and laser deposition method.The distinctive qualities of CNTs are high flexibility, and greater chemical inertness. The CNTs are widely used for water purification, medication delivery, and sensing.These materials to make it different molecules or antigens is made possible by surface functionalization, and these are directed towards target cells for immunological therapeutic impact. https://biomedpharmajournal.org/vol19no2/a-review-of-the-latest-developments-and-trends-in-biosensors-based-on-carbon-nanotubes-for-use-in-medical-diagnosis/ Antibacterial Biosensors Carbon nanotubes Drug target Drug delivery
