Nanoparticles

          The nanoparticles are being very useful in the formulation of drugs since they can imitate or modify biological processes and can provide solutions to old problems associated with the solubility, bioavailability, immunocompatibility and cytotoxicity of many traditional medicines. Carbon nanotubes are an example of nanoparticles and nanotechnology, because they have a very small diameter and can be manipulated chemically and physically. In addition, they are used in nanomedicine, principally as support supports and excipients to obtain different drug delivery systems.

The administration and formulations of drugs have been revolutionized with the arrival in science of nanotechnologies. The use of nanoparticles in nanomedicine covers the use of these as supports or templates through the functionalization or encapsulation of drugs.


           With the use of nanoformulations, a large number of drugs have improved their therapeutic function, reduced the necessary doses, as well as adverse reactions. The biomedical applications of carbon nanotubes have guided the development of a new field in therapy and diagnosis.


However, the smaller the molecule does not always lead to good results as there are times when smaller particle sizes are not beneficial for all drugs and may even unfavorably affect the formulation and effect on the patient. For example, penicillin is a drug that if we take their particles to very small sizes these instead of being absorbed better, is the opposite, their particles begin to come together, agglomerating and forming a molecule even more big than the original, thus obtaining a worse absorption
