Making your own HD microscope is a kid’s play with LEGO parts and a mobile phone

The researchers did this after realizing that the lenses in modern smartphone cameras, which cost about 4 euros each, are so good that they make it possible to distinguish even individual cells.

The scientists prepared instructions for building the microscope and also did a step-by-step tutorial to guide people through the construction process and provide information about the optical properties relevant to the microscope.

Then they tested their invention on a group of 9- to 13-year-olds and checked their understanding through a questionnaire. It turned out – unsurprisingly – that the children who were given the parts and plans to build the microscope themselves saw that their knowledge of the microscope increased exponentially.

For this part of the study, the scientists, who usually look for basic biophysical processes, were able to benefit from the input and enthusiasm of 10-year-old co-author Emil Betz-Blesa, son of project leader Timo Betz of the university. Göttingen.
