In fact, electronic chips and biochips have both a distant and close relationship. \"What they have in common is that they use very small components, they store a lot of information, and they have very large inputs and outputs.\" Yang Hongbo said. The so-called biochip output, is in the square centimeter of the chip, with a special scanner to sweep out 1 million chemical molecules reaction signals, \"line by line, as small as 0.5 microns will be swept, a million reactions will not leak.\" From the same point of view, biochips are \"electronic production, the use of biological materials\" technology.

The difference between the two is that because the material is used differently, the function is not the same.

The original intention of biochip Z was accompanied by the human genome project. \"The original purpose of the Human Genome Project was to understand why people get cancer,\" Yang said. \"But even after the project was completed, there was still no way to solve the root cause of cancer, which shows that disease is more complex than the Human Genome project imagined.\" At this time, the proposal of biochips has become a powerful tool for the study of pathology. At present, the medical application of biochips in foreign countries is mainly for cancer and drug research.

Biochips began to develop in the 1990s, has been a scientific, also involved in the human genome of China in this respect is not backward, there are many research biochip manufacturers and scientific research institutions, and has a certain impact in the international community
But they are two completely different things, the electronic chip is arranged on a semiconductor electronic unit, and the biological chip is arranged on a biological probe molecule
