Abstract

Nanoparticles (1-100 nm) provide a number of advantages, including lesser toxicity, a relatively small dosage and a high degree of manipulability in contrast to conventional treatments. The use of nanoparticles for imaging and diagnostic purposes as well as for drug or genetic delivery technologies is of special interest to the biomedical industry. Liposomes, neosomes, micelles, gold nanoparticles, silver nanoparticles, carbon-based carriers like carbon nanotubes, etc., are a few examples of the many various forms of nanoparticles. The carbon nanotubes are widely used drug carrier as they have good thermal and electrical conductivity, excellent sensitivity and high drug loading capacity, while the gold nanoparticles are popular for their biocompatibility, high surface modification and bioimaging properties. Due to the collaboration of their distinct features during conjugation, gold nanoparticles-carbon nanotube conjugates have a wide range of applications. Numerous biomedical disciplines use the conjugates of gold nanoparticles-carbon nanotubes as immunosensor, drug carrier, biosensor, electrochemical enhancer, bioimaging, nanoreactors, theranostics, and many more. Due to gold nanoparticles ability to act as a bioimager and carbon nanotubes extensive drug-carrying capability, the utilisation of gold nanoparticles-carbon nanotubes conjugates as drug delivery and theranostic has attracted significant interest.
