A new origami microscope can provide more advanced diagnostic techniques to scientists around the world, including poor areas. A laboratory from Stanford University designed a new simple microscope that only needs to fold paper, copper strips, button cells, an LED light and a spherical lens. Although the composition is simple and the cost is less than $1, the microscope meets the research requirements.
The scientists named the microscope "Flodscrope". With this tool, we can carry out sample testing in the wild, which is a great convenience for disease diagnosis in poor countries, and can also be used as a tool for children to explore. Increase their interest in science.
"One of our hopes is that every child in the world can carry a microscope with you at all times," Manu Prakash, the first author of the article, mentioned in a video on the Foldscope website.
Prakash's lab is dedicated to using physics to perform engineering costing to design solutions to real-world problems. One problem that currently exists is infectious diseases. To successfully diagnose a patient, it is necessary to determine the type of infected microorganism by imaging. But in places where infectious diseases, such as malaria, are looted, microscopes are often scarce resources. So the Prakash team hopes to find a solution to this problem, he said, "It is a challenge to design low-cost, functional devices."
(Materials needed to build a microscope)
They came up with an easy way: divide an envelope-sized card stock into five parts, including the sample placement part, the optical part, the illumination part and two lens devices, and the aperture ring surrounds the 17 spherical lenses to form the image. section. The illuminated area is the TV, an LED light and a switch. Place the sample slide on the sample placement section. These five parts are built together, swinging the slides with two fingers, focusing the sample to the optics, and the device is sturdy – it won't be damaged if dropped or stepped on three floors.
The microscope can be magnified 140-2100 times and a filter can be added. This can be used as a standard microscope, fluorescence microscope or dark-field microscope with a bright field of view. This device can even be projected on the wall for everyone to see.
Prakash said: "We have loaded this microscope onto a smartphone and imaged it through a magnetic coupler in the microscope. This device can be loaded into a variety of camera phones."
