Researchers at Stanford University School of Medicine have developed an extremely inexpensive and reusable diagnostic "chip lab" technology that costs only 1 cent to the chip. The researchers say that, like low-cost sequencing technology, this technology may bring a new revolution in the field of medical diagnostics. Related research was published online on the 6th in the American Academy of Sciences.
The new chip lab system integrates microfluidics, electronics and inkjet printing technology and consists of two parts: the first part is a silicone microfluidic control room for cells and reusable electronic strips; the second part is A conventional inkjet printer that uses commercial conductive nano-ink to print electronic tape onto flexible polyester sheets. As a versatile platform, this system can be used to analyze many types of cells. The chip will distinguish various types of cells according to the inherent electrical characteristics of the cells. The applied electric field will cause different cells in the microfluidic control chamber to be polarized. Being pulled in different directions. The new system is highly accurate and greatly improves the efficiency of cell analysis by eliminating the need for fluorescent tags or magnetic tags.
This versatile biochip system is ideal for small-scale sample testing, allowing doctors to extract a single cell from multiple cells, isolate rare cells, or count cells. The system is low in cost, and the production cost of a chip is only 1 cent, which can be made in 20 minutes. Compared to expensive flow cytometers, the cost of use is an order of magnitude lower.
Researchers point out that, as low-cost sequencing technology brings the healthcare and personalized medical revolution, this low-cost "chip lab" technology will also bring a new revolution in the field of diagnostics, driving the development of global healthcare. Even in the field of research, this system also has great application potential, which helps scientists analyze more cells in a short time and conduct corresponding basic research.
