Materials researchers at the University of Illinois, Urbana-Champaign have developed a highly conductive silver ink. In this video, Analisa Russo, a graduate student in the research group of Professor Jennifer Lewis shows exactly how to make this amazing ink, which could be used for a wide variety of hobby projects and in advanced electronics hardware.

Looks amazing, please make it available world wide and not too expensive and I’ll definitely buy it. It would be awesome to go to Staples and buy one of these pens of the shelf

This is very cool, I can see reducing the costs of printed circuit boards by using a CNC plotter to draw out circuits on pcb material.

I hope this is licensed to someone, not everyone has the lab equipment to make this. I’m wondering what the shelf live of the material is. .

any idea where to get diethanolamine? I have everything else available to make this. Is there anything else that would make a good reducing agent?
