Nanotechnology in the Health Realm

Nonotechnology has been a rapidly growing field of advanced science in recent times. Nanotechnology has found many applications in treating infectious diseases induced by viruses, bacteria, protozoan, fungi etc. Nanoparticles are effective against a virus, since a virion is of the same dimension as a nanoparticle. Nanoparticles can attach to SARS COV-2 viruses, disrupting their structure and so kill the virus. A low risk solution using antibody modified bismuth nanoparticle, in combination with an X-ray dose equivalent to a chest X-ray specifically, has been shown to kill the common bacterium Pseudomonas aeruginosa in a set up designed to resemble a deep wound in human tissue. Heparin functionalized nanoparticles have been use for targeted delivery of antimalarial drugs. Heparin is abundant and cheap, compared to treatments that involve antibodies, an important consideration, since malaria is most common in developing countries. A bone repairing nano-particle paste has been developed that promises faster repair of fractures and breakages. DNA containing two growth genes is encapsulated inside synthetic calcium phosphate nanoparticles. Many medicinal endeavours have seen the use of Nanotechnology. These and other more recent advances in nanotechnology will be presented at this conference
