Fourth Seminar Providing Tools For the Improved Diagnosis and Treatment of CancerBy Orielyz FloresNanoparticles is a powerfull tool for target tumours and transport the medicines in any parts of the body for a better treatment to cancer. According with the talk of Orieliz, the paper she discussed and what I understood, nanoparticles (in this article is utilized the gold nanorods as the nanoparticle) are used to be more specific in targeting the location of the tumour by creating a coagulation cascade. This coagulation will let know where is the exact place of the tumour and the drug for the treatment can travel directly to that place, therefore the treatment will be more efficient. Orieliz explained that with this kind of treatment the person will receive less side effects than chemotherapies does. This theme, the side effects, impressed me because, almost daily, I see people suffering the reactions of the chemotherapies by loosing their hair, which is the most natable result. This investigation will be a big contribution specially to the field of cancer treatments and later can be used to threat other diseases such as viruses or diabetes.
