Stanford scientists have developed a paper microscope called FoldScope that, unbelievably, costs less than a buck.
The main motive behind the creation of the microscope was the fight against malaria. In developing countries, about a billion microscopic examination of blood samples should be carried out per year for malaria diagnosis.
Paper microscope fits in your pocket, weighs less than ten grams, can be used for bright-field, dark-field, polarization and fluorescence microscopy, and even work as a projector. One battery lasts for 50 hours. Paper Microscope can endure any rough treatment, it can be dropped on the floor – it can withstand anything that a piece of cardboard can. Microscope image quality is sufficient enough to determine different types of infections in the field.A short training lesson will be enough for a student to learn how to make a paper microscope and conduct series of experiments.
