Thiolene-based optical adhesive was patterned by a photomask to form the microfluidic channel. This material, in contrast to PDMS, is solvent resistant . In addition to fabrication of microchannels, photopolymerization was also employed to fabricate microstructures within microchannels. Fabrication of hydrogel structures in microchannels was first achieved by functionalizing the glass-PDMS channel with 3-(trichlorosilyl)propyl methacrylate (TPM). Then the channel was filled with a solution consisting of the monomer, 50% (v/v) poly(ethylene glycol) diacrylate (PEG-DA), and the photoinitiator 1% 2-hydroxy-2-methylpropiophenone (HMPP) [960,1056].
In the latter case, the photoresist can only be sprayed, rather than spin-coated on the drilled glass plate . Drilling by a diamond-tipped drill bit (15 s per hole) is much faster than ultrasonic drilling (15 min per hole). On the other hand, ultrasonic drilling allows all holes to be drilled simultaneously with a multi-tipped ultrasonic drill bit . 9 . Another hole-forming method is electrochemical discharge machining (ECDM). In this method, an electric voltage is applied to a metal point touching the glass surface in an electrolyte solution.
Is not well understood. It was found that an increase in the NaOH concentration increased the drilling rate, possibly caused by an increase in the solution conductivity. 5-mm-dia. 133 mm/min. To assist in the electrolyte access into the hole and removal of glass debris, the cathode could be moving vertically in and out of the drilled hole . In some devices no drilling was performed, but a circular coverslip was used with the end of channel protruding out of the coverslip to reach the solution reservoir [136,137].
