Foldscope is a low-cost, portable, and foldable microscope developed by Manu Prakash, a professor at Stanford University. It was first introduced in 2014.

Here are some fascinating facts about Foldscope:

1. *Affordability*: Foldscope is extremely affordable, with a production cost of around $1. It's designed to make microscopy accessible to everyone, especially in resource-constrained areas.
2. *Origami-inspired design*: The microscope is made from a single sheet of paper, folded into a compact, functional design. This innovative design makes it easy to assemble, use, and transport.
3. *Optical quality*: Despite its low cost, Foldscope has surprisingly good optical ocratizing microscopy and opening up new possibilities for scieand discovery!
