Foldscope, the folding light microscope that costs less than a dollar

An Indian biologist creates projects for scientific tools accessible to everyone. Foldscope the last of these: an optical microscope that costs 1 dollar.

Manu Prakash is not a regular scientist. over the course of his career, the physical biologist has made extraordinary efforts to make "doing science" easier for people around the world. Prakash recently channeled his resources to invent devices that enhance "frugal science," a movement that aims to make cheap and easy tools available for scientific use in developing countries. 

This includes Foldscop to , a light optical microscope which costs less than a dollar to produce and is assembled with an origami-based folding design from a single sheet of paper with integrated lenses and electronics.

Foldscope, accessible and economic science

Foldscop to was created with the idea of ​​solving an accessibility problem to science and providing low-cost tools to communities around the world. The ultra-cost-effective paper optical microscope is portable and durable. It works like conventional research microscopes with a magnification of 140x and a resolution of 2 microns. This allows you to glimpse bacteria, blood cells and single-celled organisms, as well as larger things like insects, tissues, organic tissues and more.

Magnets are also included in the kit, allowing users to connect the microscope to their phones to take pictures of the magnification. The card can be printed in A4 size and mounted in just seven minutes.
