Glass chips are an important tool in microfluidic technology, employing glass as the fabrication material for the chips. Compared to conventional polymer chips, glass chips offer excellent optical transparency, chemical inertness, thermal stability and biocompatibility.<\/p>\n\n\n\n
These properties make glass chips widely used in life science research, medical diagnosis and drug screening. The preparation process of glass chips is diverse, and tiny structures and microchannels can be precisely fabricated by micromachining, chemical etching and other methods to realize the integration of microfluidic systems.<\/p>\n\n\n\n
Its highly controllable preparation process provides a more stable and reliable platform for experiments, while its transparency facilitates real-time observation of cells, particles or biochemical reactions within the microfluidics, providing an advanced and reliable solution for microfluidics applications.<\/p>\n\n\n

wet etching<\/h3>\n\n\n\n
The efficient processing of microfluidic glass chip channels with a depth of 20um or more, and a depth-to-width ratio above 2:1.<\/p>\n\n\n\n
The basic process of microfabrication for microfluidic glass chips includes steps such as coating, exposure, development, etching, and de-molding. Wet etching and dry etching can be chosen based on channel requirements. Wet etching exhibits isotropy, while dry etching demonstrates anisotropy. Currently, wet etching of glass is the most widely used method for microfluidic glass chips.<\/p>\n\n\n\n
