Development of nano-biosensor sprout early

Due to the tiny bio-electronic sensor, now doctors will soon through replication or improve human olfactory system, use smell to diagnose early symptoms of various diseases.

This new interdisciplinary technology is determined by the European Commission in the future, science and Technology Department of the "information society technologies projects funded through the" Spain, France and Italy jointly develop tests, scientists ultimately natural olfactory organ on the basis of the "electronic nose".

This kind of "electronic nose" can not only be applied to the healthcare industry, also be applied to agriculture, industry, environmental protection and safety, etc.

"Electronic nose" Project Coordinator Joe Joseph Pu • Sami tyre that smell of potential applications is endless, this project aims to develop can mimic human and animal smell of nano-biosensor.

They are making extraordinary. Scientists in the animal's nose in insert a micro-electrodes that contains a layer can feel the smell of protein, and then test the protein after encountering a different smell the response, the system or even be aware of the human nose is unable to detect the smell of low concentration.

"Our tests showed that the Nano-biosensor very little to respond with taste molecules, and extremely high accuracy, test some results and even exceeded our expectations," said Sami tyre, "the body positive small bio-electronic sensor technology in the odour occurred, development-an important step, also established a Nano, bio and information technology of the bio-chemical plant.

”

Responsible for the "electronic nose" works of scientists from mouse olfactory organ in the hundreds of different proteins, and yeast cultivation, different proteins can react to different smells, so that the "electronic nose" perceived almost any taste, or a combination of several kinds of taste.

Sami tyre that human nose with 1000 protein, can cause the brain to recognize 10000 different odours, and Nano-Biotechnology, the man-made "electronic nose" appear possible.

"Electronic nose" projects focus on the copy those in animal nose physical reactions occur within, and the project partners are focusing on the recognition of electronic nose odor of instruments and software research and development — olfactory system's role in the brain, they have developed a new high-precision electronic components, capable of conducting electronic measurement of nano-level, its size can only be used in very high-precision Atomic microscopy.

Sami tyre that smell technology is widely used in medicine and they will be used to diagnose olfactory organ of sensitivity, detection of bacterial infection, disease, etc.

The near future, doctors will use them for commercial cancer detection; in others, they will have a significant impact. Such diagnostic tools of the main difficulties are precise dimensioning of various diseases of smell, they as a mixture of instability in cancer patients by body fluids (such as urine, blood and pus, etc.) or breathing in concentration and health differences between individuals. In addition, it can be used to check the smell of rotting food, cosmetics and medicines, laboratory identification of pollutants, the detection of drugs and bombs at the airport to replace only a matter of chemical sensors, etc.
