2. Injection molded lab slide
Injection mold isn’t always such a challenge. NN Inc.’s PEP Group produces DNA analysis slides that feature 42 million micro-sized wells. (They are 4 microns across by 3 microns deep—you need an electron microscope to see them.) “These are typically on glass or embossed onto plastic. We can create them via injection molding, so there is significant cost savings,” Rapp said.
