Nanoparticles are excellent tools for medicine transporters.

Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. 

Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researchers can limit the molecule interaction and release into cancer cells. The nanoparticle may release cytostatics only if some other chemical or enzyme acts, as the key for opening the nanostructure. It's possible. Some kinds of enzymes can go only in the cancer cells. And then that enzyme releases ricin molecules to the cancer cells. The problem is: how to make the enzyme travel only into the cancer cells. 

Nanoparticles are a new thing in cancer therapy. The nanoparticles can stimulate immune defense. In that case, the system makes nanoparticles using the cancer cells's shell antigens. The cultured cancer cells will destroyed. Then that nanotechnical system makes nanoballs using the cancer cell's shell bites. 

Nanoparticles that are created from dead cancer cells can open the gate to cancer vaccines. 

Then those protein balls can be injected into the blood. Researchers can use those nanoparticles to help the immune system recognize cancer cells. The stem cells that create macrophages can stress in cell cultures using those cancer cell antigens, and those macrophages will be injected back into the person's body. Those particles can be the new tools for vaccines against cancer. 

If there is some special nutrient that the cancer cell uses nanoplastic or some other nanoparticles can cover using that nutrient. The idea is that those nanoparticles travel to cancer cells. In that case, the nutrient that covers those particles transports them to the cancer cells. If those nanoparticles are like yarn balls, they might open when they travel in the ion pumps. And that leaves the ion pump open. Or, those nanoparticles can mark the cancer cells for the immune system. 

In the most advanced systems, the nanoparticle can involve the DNA bite that orders those cells to die. The nanoparticles can also use physical methods to destroy the cells. The idea is that the nanoparticles travel in the cell. There, they can release some fibrine or kevlar strings. 

Or the soundwaves or some other thing can make those nanoparticles resonate. That resonation can destroy internal structures in the cell or mitochondria. When that nanoparticle resonates, it creates pressure waves that destroy the important cell organelles.
