How do 1–100 nm particles treat deadly diseases?

Nanotechnology has revolutionized the methods of cancer diagnosis and treatment. The nanoparticle drug delivery system utilizes tumor and tumor environment characteristics by precise targeting. Nanoscience solves the limitations of conventional cancer treatment, such as lack of specificity, cytotoxicity as well as problem of multidrug resistance.

Nanoparticles can be delivered to the desired organ as a vaccine. As a result, it raises the concentration of T cells or presents artificial antigen cells.
For example:
Nanoparticle albumin-bound paclitaxel followed by FEC was successfully used to eliminate locally advanced breast cancer in the treatment of 66 randomly chosen women. Clinical trials have been carried out in NSABP Operations Center in the United States.
