  1. Teach your #microscope how to print: Low-cost rapid-iteration #OpenSource #microfabrication for #biology:

    - no cleanroom required
    - replace SU-8 #photoresist & silicon wafers by #3Dprinting #resin & microscope slides
    - #fluorescence microscope-based maskless #photolithography
    - achieve µm-scale precision across cm-sized areas

  2. Been working on some electrode patterns, starting to get some nice results. 🥳

    Edges are a bit fuzzy/burry since I'm sputter depositing rather than something more line-of-sight like thermal evap. Getting a better dep method is high on the todo list.

    Resist stack is an MMA/PMMA bilayer, substrate is silicon + ~100nm CuO, and electrodes are 150nm of aluminum via lift-off.

    In theory, these should act as metal-semiconductor-metal photodetectors. Unsure if my test gear is sufficient though, might need to upgrade my electronics a bit. We'll see! 🤞
