Israeli scientists have developed a biological transistor, which is also used as oled can act, designed on the basis of proteins, blood, mucus, and milk are met. The advantage of such a transistor is that it is biodegradable.
The necessary proteins each have different functions. In the blood is the protein hemoglobin, that oxygen can absorb. This is by scientists used chemicals with the biological structures to react, so that the transistor the desired semiconductor properties. In addition, milk proteins are responsible for structure on the whole. Finally, proteins from the mucus responsible for the optical properties of the transistor: these are used to make the dyes for rgb light separated from each other. For example, the whole oled act.
Scientists have the body proteins in a coating is applied, maintaining the correct structure after drying by itself would form. It does according to the makers, little matter what material is chosen. There is a thin layer on a nanometer scale is formed. This structure acts then as semiconductor. Typically a siliciumsubstraat used for the production of semiconductors.
According to the Israeli scientists from the university in Tel Aviv is worked to the biotransistors with oled capacities to make them suitable for use in displays. In the longer term, however, the system can be used in multiple types of electronics. The advantage of the use of transistors which biological molecules are based, is that they are easily degradable. That must be the waste and improve the impact on the environment decrease. However, it is likely that commercial production of chips using such transistors is still years in coming.
Two years ago, a California group of scientists already agree to a transistor to develop that part of biological molecules is based. This was the ATP-molecule used in the body for energy supply. In addition, there was a layer added that is similar to a cell membrane.
