Nanotechnology is the area that studies matter in dimensions between 1 and 100 nanometers. On this measurements materials show other features and applications, in addition to which are known. In other words, nanotechnology means engineering of complex machines, materials and circuits built atom by atom or molecule by molecule.
The importance of pharmaceutical nanotechnology for therapies with drugs resides on the possibilities to deliver drugs of low molecular weight as well as macromolecules like peptides, proteins and genes, in a localized or guided manner to certain tissue of interest.
Lately, there have been investigations about controlled drug release's nanodevices, that can be used on therapies against breast cancer.
Until now, the work has focused in cellular essays with some positive results that could open new ways to improve the efficacy of some drugs used on this therapies.
The principal novelty of this nanodevices is that the molecule that covers it not only controls when the drug is released, it controls where is released too, directing the drug to some specific cells.
I chose this technique because breast cancer is the more lethal tumor among women worldwide, then, investigations aimed at identifying new therapies or improving which are known are a field of intense activity, and as a future pharmacist is part of our work to give wellness to people.
However, it is necessary the increase of the regulations in order to assure the safety of nanoparticles, it is considered that the toxicity, epidemiology and bioacumulation of fabricated nanomaterials are so far to be studied; in spite of this, the application of nanotechnology in healthcare and for development of personalized medicine appear to be hopeful.
Nanotechnology would be such a succesful tool!
