Anticancer Drugs And Its Effects On Cancer Cells

Decent Essays

Abstract Many attempts were made to treat different kinds of cancer, the problem was the lack of specificity of anticancer drug towards cancer cells resulting in severe side effects, but with the new system for drug delivery system –the nanoparticles –this problem could be avoided. Nanoparticles are very small particles from 1 to 100 nm with different shapes and sizes made of variety of materials .Nanoparticles have many applications in different aspects especially medicine including therapy and diagnosis. Nanoparticles that used in therapy and diagnosis are called ' ' theranotics ' '. The most important application of nanoparticles …show more content…

(Wilczewska et al., 2012) What are nanoparticles ? Nanoparticles are very small particles measured in nanometers and ran- ge from 1 to 100 nm they have different shapes spheres ,rods ,cubes, and caps. Nanoparticles can be made of variety of materials such as gold , platinum , and iron dioxide .(Faraji and Wipf, 2009) . Applications of nanoparticles : Nanoparticles are used in different aspects including medicine. In medicine nanoparticles can be used in immunology , oncolo- gy , endocrinology ,ophathalmology ,….etc. In addition to all these areas nanoparticles can also be used in more specialized areas such as brain targeting , tumor targeting ,and gene delivery . Further applications of nanoparticles technique include their use as carriers for sustained and controlled drug delivery, active and passive delivery of bioactives , vaccine delivery , and gene silencing (Faraji and Wipf, 2009) .
