In the medical field, MEMS is used to manufacture various medical devices and diagnostic tools, such as microfluidic chips andBiochips, etc. In short, MEMS is a technology with a wide range of application prospects, which can be applied in a variety of different fields to bring convenience and benefits to people's lives.
MEMS is developed with the development of semiconductor integrated circuit micro-machining technology and ultra-precision machining technology, and MEMS processing technology is also widely used in microfluidic chips and synthetic biology and other fields, so as to carry out the chip integration of laboratory technology processes such as biochemistry.
Simply put, a MEMS chip is a chip that combines a tiny mechanical structure with electronic components.It uses micro-nano manufacturing technology to manufacture tiny mechanical parts on the surface of the chip and interconnect with circuit components. These tiny mechanical structures enable sensing, measurement, control, and execution.
Functions and applications: MEMS is commonly used in sensing, execution, and control applications. They can be used to manufacture micro-electro-mechanical systems such as accelerometers, gyroscopes, pressure sensors, and micro-sprinkler heads. Chips are widely used in computers, communication equipment, home appliances, automotive electronics, medical equipment and other fields, for storing and processing data, control circuits and operating systems.Microfluidics refers to the science and technology involved in systems that use microtubes (tens to hundreds of micrometers in size) to process or manipulate tiny fluids (microliters, nanoliters, or even abliters in volume), and is an emerging interdisciplinary discipline involving chemistry, fluid physics, microelectronics, new materials, biology, and biomedical engineering.

Microfluidics isThe sample preparation, reaction, separation, detection and other basic operating units of biological, chemical and medical analysis processes are integrated into a micron scale chip to automatically complete the whole process of analysis. Because of its great potential in biology, chemistry, medicine and other fields, it has developed into a new research field of biology, chemistry, medicine, fluid, electronics, materials, machinery and other disciplines.
microfluidic chips and liquid biochips are new biochip technologies developed after microarray chips, biochip technology is the basic content of system biotechnology. biontbiochip (biochip or bioarray) is based on the principle of specific interactions between biomolecules, the biochemical analysis process is integrated on the surface of the chip, so as to achieve high throughput and rapid detection of DNA, RNA, peptides, proteins and other biological components.
1, microfluidic technology is a technology to control and manipulate fluids on the micron scale. Microfluidic technology uses micrometer-scale channels, pumps, valves, and other micro-devices to precisely control and manipulate small amounts of fluid.Usually a liquid or gas).
2. Microfluidic technology is a manufacturing technology of miniaturized fluid system. It realizes the design, preparation and control of miniaturized fluid system through the two core technologies of micro-nano manufacturing and microfluidic, and combines the knowledge of biology, materials, medicine, engineering and other fields. In practical applications, microfluidic technology is widely used in biomedicine, drug delivery, environmental monitoring, energy and other fields, such as microfluidic lab-on-a-chip, drug controlled release system, water quality testing equipment, etc.

Biochip technology: The application of biochips in food safety detection mainly includes the detection of food safety and hygiene, food nutrition components, food raw materials, etc. A large number of biomolecular samples were solidified on the surface of the support with a certain sequence standard by using a variety of methods such as photoguided in-situ synthesis or microdot sampling.
The basic principle of the gene chip is to put a variety of gene oligonucleotide dots on the surface of the chip, prepare a fluorescent labeled probe after PCR amplification of microbial DNA, and then hybridize with the oligonucleotide dots on the chipFinally, the fluorescence distribution pattern is quantified and analyzed by the scanner to determine whether certain specific microorganisms are present in the test sample.
The application of gene chip technology in food testing, it can be said that this is a very sophisticated intelligent application, so now many places have not been used, this is generally through some mechanical chip detection.
At present, biochip technology is one of the most widely used for food safety detection of high-tech biological detection technology, the detection principle is to test the sample placed on the surface of the chip, and then based on the specific affinity between biomolecules
