The urgency of the thesis Today, the development of science and technology has made great strides in biomedical science but human beings are still facing many diseases, most notably cancer. There are many cancer drugs available on the market. However, the biggest disadvantage of many cancer drugs is that they are less soluble in water or more readily excreted. Besides, the selectivity of these drugs is not high, and more or less affects healthy tissues and results in side effects including nausea, diarrhea, anemia or reduced immunity of the body. This is due to most treatments not only affect the tumor locally, but also affect a large part of the body's normal tissues and organs. To overcome the shortcomings of the method above, researchers have applied nanotechnology, using .
