The portable reader provides a low cost way to quantify our paper-based sensors. It is composed of off-the-shelf electronic components that are housed in a laser-cut acrylic box. Starting at the top of the box, the main components include the: LED layer, cartridge layer, electronic sensor layer and the bottom stack. The bottom stack is composed of an Arduino, data shield and SD card, as well as a battery shield and Li ion battery that can be recharged using a micro-USB. Reactions are read by inserting the cartridge containing the paper-based reactions into the slot between the LED and sensor layers. Once turned on, the reader measures the transmission of light through the paper every minute using an LED with a wavelength that matches the maximum absorbance (570 nm) of the purple toehold switch reporter.
