Nanotechnology Role in Cancer Diagnosis and Therapy

Abstract

Cancer is a prominent cause of death and ill health around the world. There is still a deficiency in the efficacy of various cancer medications, despite the fact that numerous ways have been devised to minimise mortality, alleviate chronic pain, and improve the quality of life for those with cancer. For best cancer treatment, early detection and use of drugs with high specificity to minimise side effects must be taken into consideration. Conventional cancer diagnostic and therapeutic methods have become increasingly hazardous and refractory, leading to the development of new strategies, such as nanotechnology, to enhance diagnosis and reduce disease severity. Cancer detection and therapy have been revolutionised by nanotechnology. Cancerous cells can be detected and the very toxic medications delivered to them in vivo by this device. Some of the materials utilised in cancer detection are nanoshells, carbon nanotubes, quantum dots, supermagnetic nanoparticles, nanowires, nanodiamonds, dandrimers, and freshly created nanosponges. As a result, nanotechnology has been examined for the detection of extracellular biomarkers and cancer cells, as well as for in vivo imaging, because to its great sensitivity. The most recent breakthroughs in nanotechnology for cancer diagnosis and treatment are summarised in this article.
