Abstract

The invention provides a glass-PDMS film-glass sandwich microfluidic chip manufacturing method. A polyester PET sheet is used as a transferring sacrificial layer to treat a structured PDMS film, and through plasma processing, the treated structured PDMS film is sandwiched between two glass substrates so that a glass-PDMS film-glass sandwich microfluidic chip is formed. Through ingeniously use of PET as a carrier for transferring a treated delicate structured PDMS film so that high efficiency transferring of the structured PDMS film is realized, a structured PDMS film manufacturing process is simplified and technology difficulty and a time cost are reduced. Through plasma processing, the structured PDMS film is sandwiched between two glass substrates so that the glass-PDMS film-glass sandwich microfluidic chip is formed. A glass material has low permeability so that the chip has low solvent volatility and the problem of PDMS microfluidic chip solvent volatilization is solved.

Description

technical field [0001] The present application relates to the field of microfluidic chip design, in particular to a method for manufacturing a glass-PDMS film-glass sandwich microfluidic chip. Background technique [0002] With the development of technology, people have higher and higher requirements for the fabrication methods of sandwich microfluidic chips. [0003] Existing sandwich microfluidic chips include sandwich PDMS microfluidic chips coated with parylene (PA), sandwich PDMS microfluidic chips coated with polyvinylidene chloride (PVDC), and polyvinylidene chloride (PVDC) coated sandwich PDMS microfluidic chips. Vinyl alcohol (PVA) film is used as a transfer sacrificial layer to make sandwich PDMS chips, but these sandwich PDMS microfluidic chips have a cumbersome processing process, a long time period, and high cost. [0004] Therefore, how to effectively realize the fabrication of the sandwich microfluidic chip, simplify the processing process, shorten the time p...
