The current drug delivery system for cancer treatments may have shown positive results, but they definitely have negative consequences as well. These drugs are toxic, have poor tissue selectivity, and continuously using them may increase resistance against them [38]. The toxicity of a drug is always a concern because most drugs are not tissue specific, i.e. they have the same effect on normal and abnormal cells. The use of nanotechnology makes it possible to have a specifically targeted drug delivery system. From size manipulation to creating various delivery vehicles, nanotechnology can help specifically to target and assemble in tumor cells [39].
