Cancer dedection - Essay ExampleCarbon nanotubes, silicon nanowires, favourable particles, quantum dots etc can be apply to fabricate nanotool sensors which may be used for detection of malignant neoplastic disease biomarkers accurately (Zhang et al,2013,71).Recently colloidal gold or nano-gold particles had been used to distinguish cancerous cells from non-cancerous ones and by interacting these particles with light the cancerous cells were burnt up (Prajapati et al,2010). Thus nano-particles are not only used for detection but by chance used for its diagnosis of cancer as well.It is true that nanoparticles are bestowed with unique properties which are both a boon and a bane. Much of its efficacy is mutualist on the way these particles are engineered. There is no way for the nanoparticles to target the tumourous cells solely and chances are that minimal damage maybe inflicted on normal kind-hearted body cells as well.However, since this is a relatively new field ,researchers ar e still to find out the negative points about nanotechnology. However, so far nanotechnology has shown confirming results especially in the field of medicine.Questions are raised on the ethics of using nanotechnology especially for health purposes. The engineering of materials at the atomic or molecular level may seem unethical to some. However, there is no doubt about the fact that nanotechnology is a revolution in the medical field which makes it easier for us to fight against diseases more efficiently.Oncologists are of the opinion that nanotechnology maybe the answer to many unanswered questions about cancer detection and treatment. The accuracy and efficacy of nanotechnology in cancer detection and subsequent diagnosis makes it a promising diagnostic and detection tool. More research should be undertaken to study its positive as well as its negative
