You want to shape a transparent material with lithography, then cover it with another layer of the same material and shape it. However, you have to align the pattern on the 2nd floor with the pattern below. As both layers are transparent, the alignment markers on the bottom are hardly visible under the microscope. How […]

ANSWER: Yes. You can see the result of two-step lithography using acetate mask in the photo above. The acetate mask is an inexpensive solution and can provide great results for many patterns over 100 microns. However, acetate mask has a few weaknesses: 1. The patterns you have designed cannot be printed very smoothly as in […]

Our microfluidic chip, which we produced to examine the interaction between cancer and nerve cells, is used with real cells. The channel on the right is about 50 microns in height. So almost half the length of the hair. Green colored large circles are cells planted into the microfluidic chip. There are channels on the […]
