Nanoparticles are described as particles that have less than 100 nanometre (nm) in a dimension (Khan and Arif, 2012, p. 85). Zinc (Zn) is one of the elements that has been known for its anti-cancer properties (Kim et al., 2013). On the other hand, silica nanoparticle (SiO2 NP) is one of the nanomaterial with a huge application particularly when it comes to the project of Nanomedicine (Sahu and Casciano, 2009, p. 125). As such, this project aims to investigate how the functionalizing of SiO2 NPs doped with Zn could affect its cellular uptake.
To learn more about the research topic, this project aims to see how the surface charge of the SiO2 NPs doped with Zn has an effect on cellular uptake. This project will also seek to determine whether or not surface functionalisation of SiO2 NPs doped with Zn could create significant changes within the cellular uptake. In the process of conducting a systematic literature review, it is possible for the reader to gain more insight on what has already been known and unknown when it comes to the possible effects of surface functionalisation of Zn SiO2 NPs doped with Zn on the cellular uptake and its potential for cancer therapy.

[...] Both Zn and Si nanoparticles are used in cancer treatment. It is, however, important to use the two nanoparticles because their combination have been proven to promote synergism among different drugs, especially against the cancer cells. To analyse the two nanoparticles, the literature review is divided in various sections. The first section is about both Zn and Si nanoparticles, which compares the two NPs and the importance of using them collectively for cancer treatment. The properties and mechanisms of Zn and its use to treat cancer are analysed in another section. [...]
[...] Therefore, to avoid such health complication, having a better control of the NPs' surface, prior to its actual application when treating cancer cells, is very important. Even though Ramasamy et al. (2014) strongly suggest the need to modify the surface of ZnO NPs with SiO2 NPs, one should consider the fact that SiO2 NPs are capable of agglomerating together due to its OH bonds on the surface or electrostatic forces (Gradzik, El Fray and Wisniewska, 2011;Bagwe, Hilliard and Tan, 2006).
