Shout out to Saad for introducing me to foldscope on my last day of summer internship at Stanford. Every now and then, I carry foldscope in my backpack in case I see something interesting and want to check it out. A couple of weeks ago, I forgot to sign up for microscope in lab, and as a consequence, I wasn’t able to run experiment. Luckily, foldscope came to rescue and kept me busy. Since reading Professor Prakash’s post on reflection mode, I’ve always wanted to try it out. So, I attempted to make a quick simple oil water microdroplets to see if I can visualize them. Turned out I can with foldscope using high-speed camera on my phone. Indeed, it did blow my mind.
