Organ on a chip<\/strong><\/span><\/p>\n

The organ chip is a chip system developed based on microfluidic technology, which can simulate different organs of the human body. This technology implants human cells into the chip, and the chip simulates the human body environment (such as pressure, shear stress, and concentration gradient) to form an in vitro<\/em> model, and realizes tests that are closest to the real internal environment, such as drug screening, drug safety testing, and food safety testing. It is a powerful tool for constructing complex disease models and conducting preclinical new drug development.<\/span><\/p>\n

3D bioprinting<\/strong><\/span><\/p>\n

3D bioprinting mainly uses cells, biological hormones, growth factors, intercellular substances, and other substances to print out human living tissues with biological functions. The emergence of this technology can help scientists build high-bionic chip models that simulate the microstructure and function of the heart, lungs, kidneys, muscles, tongue, bone marrow, and intestines in batches. It is widely used in many fields such as cell development mechanism research, pathogenic mechanism research, and drug development.<\/span><\/p>\n

Organ chip engineering simulates the real tissue or organ environment by controlling cells, extracellular matrix (ECM), and other microenvironmental factors to elucidate the physiological or pathological mechanisms of cellular essence. Existing chip models are mainly based on polydimethylsiloxane (PDMS) microfluidic devices, while traditional soft lithography requires cumbersome production procedures with long cycle times and high costs. 3D printing technology can effectively design and automatically print micron-scale devices, and construct complex organs or tissues by precisely manipulating cells and biological materials. The popularity of 3D printing provides more options for the application of organ chips. The combination of 3D printing and microfluidic technology in the construction of organ chips can provide more complex flow channels or chambers, presenting in vivo<\/em> structures with 3D cell distribution, heterogeneity, and organization-specific functions.<\/span><\/p>\n
