1. Researchers have developed a new method for more efficiently labeling proteins that is faster, higher yielding, and less disruptive to protein and cell function than current methods. 2. They engineered mammalian cells to incorporate an artificial chemical handle that allows a small fluorescent molecule to rapidly and stably attach to proteins of interest, enabling new types of cell biological studies. 3. Understanding protein interactions with nanomaterials at the nanoscale is important for controlling their function in applications like biosensing and tissue engineering, and for developing new composite materials.

4. INTRODUCTION Proteins functions. Proteins alterations. For those functions and posible alterations is so necesary have clear knwoledges about the proteins and the methods to study them .

9. The fact that actually the advance isn’t only the knowledge of all protein domains but also in the study and the methods used to do it, is very important. These advances allow us to leave behind the mistakes that were committed with the above methods, to start with new technologies more efficient, effective and less invasive for humans, and approach us to the cure of a lot of diseases.

14. Nanotechnology has had important impacts on many aspects: industrials, commercials and especially in the medical field, because it has become a minimally invasive technique for the man. The fact that is already in use to control the orientation and structure of proteins allows to have control over the diseases that are generated before the alteration of any kind of these molecules, allowing in the future the prevention and cure of any protein affection. For that is so important continue with the investigations of the form to evaluate and progress in knowledge about human components.

15. The proteins are involved in some many diseases that affect human, in a mild or severe way. This alterations can occurs in fetal life or in an old age, as a consecuences of bad habits or autonomous appearance. The pathologies generated by an alteration of these molecules are so varied because they´re implicated in so many processes relevant for human, and if one of that function suffer an alteration, maybe put the life of the patient in risk. For that reasons is necesary advance of research of methods that allow us to progress in the fight with those many affections.

16. Proteins are one of the most complex and volatile constituents of our body, because they change rapidly its direction or structure and therefore its ability to interact with other molecules . The fact that the proteins have these propertys, show us that its imposible continue with the same investigation method for years, because these molecules like all in life are changing all the time, and we have to be at the same level of that progress, we cant stay back. And if we get it, we can be more near of the cure of some many diseases.

17. Proteins engaging in processes that could be considered simple such as transportation to complex and vital as the expression of genetic material. These molecules engaged in a lot of processes of man, and of their effectivity depends the type of life quality of a person and in the extreme case the life. The investigations about the methods to control the proteins processes and their expression, are so relevant in medicine because with the progresses and new knowledges people can have a better life.

18. The importance of a clear understanding of their structure, function and interaction with other molecules, is find possible pathologies that may occur, prevent them and in the latter case cure them. The principal interest of the health personal must be prevent and care the integrity of the patients, and if it wasnt posible they have to treat to save the life of the person. Thats why the investigations and science are so importante, because these ways we can find the mode to prevent the apparition of diseases that affect the integrity of the patients or in the latter of cases cure the affection.
