Abstract
The present invention relates to a method for manufacturing high-resolution microfluidic structures by means of the modification of the sealing temperature and photolithography.
Claims8
A method for manufacturing microfluidic structures comprising:
- a) depositing a thermosetting polymer photoresin on two independent substrates of biocompatible polymer material
- b) performing photolithography on the surface of the deposited photoresin at low temperature, below the glass transition temperature of said biocompatible polymer material, to form microchannels
- c) sealing the obtained wafers, by means of superimposing them, facing one another by the surface with the photoresin, at temperatures below the glass transition temperature of the polymer material and applying pressure.
