Starting from a classical laboratory microscope of tens of thousands euros (Leica DMi8), to a cheap compound microscope in the range of 300 euros (Swift 380t), to Open microscope OpenFlexure, a 3D printed microscope that costs less than 100 euros, and is already used for detection of malaria parasites in blood samples. As part of this research, we thought it would be possible to make a cheap microscope that could detect Schistosoma eggs in our microfluidic channel. For this reason, we developed an ESP32 microcontroller-based miniature microscope, for less than 10 Euro in parts with a WiFi connection and can be battery-operated (Figure ). The development of this microscope, as well as all the files and the instructions to build it, are live on GitHub,[24] and a comprehensive article will be published soon. This microscope is the perfect companion for the microfluidic device as together can fit in a jacket pocket and easily be brought along in the field. All the microscopes tested were able to resolve the eggs for identification, meaning that using the size-sorting microfluidic device will also be possible to discriminate the features on the eggs to identify various Schistosoma parasites, including S. mansoni and S. japonicum.
