After several prototypes, the researchers released blueprints earlier this month for a ‘LudusScope’ in the international scientific journal PLOS ONE, offering kids of all ages a playful window into the world of microbiology.
‘It's a microscope that you can 3D print and build yourself,’ Ingmar Riedel-Kruse, an assistant professor of bioengineering at Stanford, told Reuters.
After it is assembled, tiny, light-responsive organisms called Euglena swim on a microscope slide surrounded by four LED lights. The lights are controlled by a joystick, allowing users to control the direction in which the microbes move.
‘You turn microscopy from something that is purely observational into something that is interactive,’ Riedel-Kruse said.
The final component is a smartphone that attaches to the eyepiece of the device, transforming it from a simple interactive microscope into a rudimentary gaming platform and research tool.
The scientists at the Palo Alto-based university have developed software programs that overlay on top of the image of cells. By selecting specific cells, users can influence their movement and guide them through a maze that resembles the 1980s video game Pac-Man. Kids can also play soccer by steering their microbes through goal posts.
The games, according to Riedel-Kruse, evolve into basic research.
‘You can select a cell, track it and collect data about it that you can then analyze and discuss,’ Riedel-Kruse said. ‘You can really do simple research in educational settings.’
Using the plans publicly published, anyone can build a LudusScope now, but Riedel-Kruse said assembly is complex.
He plans to use recently awarded grant money to further develop the microscope into a ready-to-use science kit that he hopes will be commercially available in 2018.
