Nanotechnology: A Way for Active Targeting of Cancer Cells

Since cancer is one of the top causes of death, researchers have been working hard for cancer management. Creating drugs that can be utilized for both early detection and efficient treatment, is one of the most challenging parts of cancer treatment. Traditional cancer treatment is linked with a high risk of serious chemotherapeutic side effects and occasionally lacks precise technology for early tumour identification. It was thought that a medication that could serve as a "magic bullet" and could only recognize cancer cells, was required for better therapeutic ratio, defined as the distinction between how treatment impacts cancer cells against healthy tissues. Nanoparticle systems provide numerous potentially efficient approaches for developing customized cancer detection and treatment medications. There are two methods for targeting nanoparticles: passive targeting and active targeting. Nanoparticles can be effectively localized inside the tumour microenvironment with passive targeting. Due to their active targeting, nanoparticles can be actively taken up by tumour cells.
