This review deals with applications of nano-biochemical materials., Due to the failure of some conventional medical treatments to reach the most accurate tissue in the body, especially for cancer patients, many researchers have resorted to finding quick and therapeutic alternatives that directly treat tissue without leaving side effects, with a prior study of the toxicity of some types of nanoparticles in tissue therapy through nanocapsules. Ultra-fine and the capsule material is excreted after performing its tasks and is excreted with urine and excreta. Also, some biochemical treatments affect the stomach and others, so the researchers resorted to using a small nano-capsule that contains a mixture of treatment with a substance that helps to remove the excess from it with the exit, and thus they are substances that do not affect the rest of the body’s other tissues or healthy tissues, if the body gets rid of the excess of them.
