Estudo sobre nanomedicina e suas aplicações

Abstract

In this work we going to introduce a litlle of what are the nanoparticles, yours aplications like in medicine and cosmetics and the risks who can have. The nanotecnology is the draw, description, production and aplications of structures of manipulations controlled of size and form in manomectric scale. One of the your principal caracter of the nanotecnology is the manipulation of matter in a atomic scalle, creating .News products or improving the existing . To visualize matteries in manometric scale is necessary be used electron microscopy or be microscpy of sweeping. One area of the nanotecnology who comes growing with the past of years is the nanomedicine, who made with the treatments, for exemplo the cancer, be less invasive and more eficiente. Our principal focus were the nanoparticles of gold, these are very used in medicine and aesthetic, because have optical properties eletronics differentiated from the others materials, are considered less toxic because the gold inertia, Are utilized like agents in biomedic detection and contrast for image. Nanoparticles of gold are too used in cosmetics to be biocompatible and can be used to improve the efficiency of products using at skin or hair due the size, nanoparticles penetrate more easily at skin and scales of hair. The risk of use must be avaliated with base in features fisic- chemistry in each material.
