Connection: How the microscope connects to your smartphone is also important. Generally, WiFi and USB models have a higher magnification range but are mostly less portable than manual ones. Moreover, some USB models do not support all smartphone operating systems. Meanwhile, the manual ones have a clip-on adapter that allows you to attach it directly to your phone’s camera. Although they have a lower magnification range, they are pretty much straightforward to use with less complication.

The smartphone frame was designed using SolidWorks (SOLIDWORKS Corp, Waltham, MA, USA) and 3D printed with polylactide resin (MakerBot ® PLA resin, MakerBot ® Industries, New York, NY, USA) using a MakerBot ® 3D printer (MakerBot ® Industries, New York, NY, USA). The smartphone sat on the top of the frame while a microfluidic biochip was inserted from the side ( Figure1A). The dimensions of the 3D frame were 100mm in height, 180mm in length, and 85mm in width. Design, fabrication, and validation of microfluidic biochip
