What we’re doing in the lab

For those of you interested. MAPLE DW – Matrix Assisted Pulsed Laser Evaporation Direct Write is a way of using laser beam to “fleck” off the underside coating of a transparent sheet onto a bottom sheet. It’s like using carbon copy paper but instead of a pen, you use a laser beam, and instead of carbon you can use fancy materials like gold, cells, or biologicals. Then you write with those substances at a microscopic level. So far, I’m trying to see if we can pull this off with the laser cutter. We’re not sure if we can pull this off with the laser cutter. :)
