Microfluidic Chip

The microfluidic lab on a chip, also known as the lab-on-a-chip or microfluidic chip technology, integrates basic operation units such as sample preparation, reaction, separation, and detection through biological, chemical, and medical analysis into a micrometer on the chip, the whole analysis process is completed automatically.

Because of its great potential in biology, chemistry, medicine, etc., it has developed into a new research field that intersects biology, chemistry, medicine, fluids, electronics, materials, and machinery. Due to the micron-level structure, the fluid in the microfluidic chip displays and produces special properties that are different from the macroscopic size. Therefore, the unique analysis of the development department produces the performance.

The material includes Silicone, Glass, High polymer.

Silicone, as Insulation and light transmittance are poor, deep etching is difficult, and low success rate of silicon substrate bonding, that’s why the silicone material not widely used.

Glass is widely used in the manufacture of microfluidic chips. It uses lithography and etching technology to engrave the microchannel grid into glass materials. It has the advantages of a certain strength, good heat dissipation, light transmittance and insulation, and is very suitable for common sample analysis, but the cost is high.

High polymer materials have been applying to Mass production depend on Low cost, easy processing and forming, can be mass production. Include PI, PMMA, PC, PET and etc.

The style of Microfluidics:

	Straight channel chips - Microscopy-slide format
	Straight channel chips - Microtiter-plate format
	Straight channel chips with waste chamber - Microscopy-slide format - Fluidic Interface: Luer
	Cross-shaped channel chips
	H-shaped channel chips
	Sample preparation chip – Fluidic interface: Mini Luer
	Field-flow fractionation chips
	Meander and continuous-flow PCR chips
	Membrane chip
	Micro mixer
