1、Basic principles of Emulate organ chip

1. Fundamentals of Microfluidic Technology: Microfluidic technology, also known as organ chips, is a technique for manipulating fluids at the micrometer scale. It achieves complex biochemical experiments in small spaces by precisely controlling fluid flow, mixing, separation, and other operations in tiny chip channels. The Emulate organ chip utilizes this technology to construct structures and functions similar to human organs on tiny chips.

2. Construction of biocompatible materials: The selection of biocompatible materials is crucial in the manufacturing process of Emulate organ chips. These materials typically have good biocompatibility and degradability, and can Emulate the physical and chemical properties of human tissues. For example, biomaterials such as PDMS (polydimethylsiloxane) can be used to create scaffolds with complex structures through technologies such as 3D printing and microfabrication. These scaffolds provide the basic environment for cell growth and development.

3. Microfluidic channel integration: The core part of the Emulate organ chip is microfluidic channels, which are used to Emulate fluid channels such as blood vessels and lymphatic vessels in the human body. Microfluidic channels can be tightly integrated with biomaterial scaffolds, simulating the physiological functions and pathological changes of human organs through precise control of fluid flow and substance exchange within the channels. For example, it can Emulate the flow of blood in blood vessels, the distribution and metabolism of drugs in organs, and other processes.
