Microscopes are something found in laboratories and are generally bulky. Recently, several researchers at Stanford University in the United States invented a paper-folding microscope, which consists of only a few pieces of greeting card paper, a scattering plate, an LED light, a ball mirror and a watch battery. It is light and portable. It mainly uses an extremely short optical path (ranging from 2 mm to 200 microns) to observe detection objects. It can clearly observe more than 20 kinds of viruses and microorganisms, including malaria, bringing new innovations to medical care and mobile medicine in poor areas. Extremely broken. It only takes about 10 minutes to go from prototype to finished product.
The most important thing is that it is very cheap, with each paper folding microscope costing only 50 cents to 3 US dollars. Small and exquisite size, shock-resistant and waterproof materials, it is very suitable for students from major universities.
