Before use the wafer has to be cleaned. A classic cleaning is recommended as described here. If you are in a clean room, you can clean it with piranha solution (H2SO4+H2O2), outside a clean room you can use acetone. WebWash the PDMS slabs by placing them sequentially in beakers containing 0.5 mM NaOH, 70% EtOH and purified water. For each washing step, sonicate the device-containing beaker for 2 min in an ultrasonic bath. Ensure that the devices are rinsed in purified water between each washing step. 2. help pay rent assistance
