A team of researchers from Boston University and Tufts University near Boston, has shown an infrared spectroscopy technique that can recognize directly the vibrational features handles extremely small amounts of proteins, the machinery involved in the maintenance of living organisms . The new technique exploits nanotechnology to overcome several limitations of current conventional techniques used to study biomolecules. And it could lead to a new set of tools to study biomolecules.

Nanotechnology and Health: Conclusions

1) How Nanotechnology will allow a faster and more reliable diagnosis of diseases?

In this sense there is agreement that nanotechnology will be the main reference for a fast and reliable diagnosis of many diseases. To do this, one of the main weapons will be biosensors, which needed to be compact, portable, multifunctional and fast. This will be quickly analyze analytes in blood, urine, tissue or saliva (not only human) and that we may report the concentration of certain components, markers, drugs, antibiotics, viruses, etc.. Another important technique in the detection of diseases and tumors based on magnetic resonance imaging, thanks to nanotechnology may allow the use of advanced contrast agents to increase the spatial resolution and contrast of images enabling the detection of anomalies in early states.

Nanotechnology and Health Innovation

Nanodiagnosis In the area of the biosensor technology is one of the most promising, compact systems consisting of analysis composed of a biological recognition (DNA, protein, etc.) That detects an analyte (glucose, antibiotics, etc. ) and a transducer of this detection to quantify the amount of analyte. The most successful devices to date are biosensors for the detection of blood glucose, which were introduced commercially in 1975 by the company Yellow Springs Instrument Company. But the range of applications of biosensors is immense. For example, in the food industry is a priority the detection of certain prohibited items, such as antibiotics used for artificial fattening of animals or to make them resistant to diseases but very harmful to human health.
