Drug delivery by nanotechnology for censer therapy

Nanotechnology in the field of drug delivery is rapidly developing to overcome several limitations of traditional drug delivery systems and to be used as a superior treatment for cancer treatment. Conventional chemotherapy has some serious side effects, including damage to the immune system and other organs due to non-specific targeting, lack of solubility, and the inability of the drug to penetrate the tumor core, which causes disruption in treatment. Nanotechnology has provided an opportunity to directly access cancer cells in a selective manner by increasing cellular uptake and drug effectiveness. Nanotechnology tools can be used to recognize cancer cells and deliver selective and precise drugs without avoiding interaction with healthy cells. In this study, the ability and application of nanotechnology tools with different strategies and with unique identification features in the detection of cancer cells and in the transfer of drugs and the delivery of specific drugs inside specific cells have been discussed, which is based on successful research in this field. It has been done, it shows that nanotechnology tools are suitable for removing the side effects of common cancer treatments and also increasing the effectiveness of the drug.
