Abstract
We report the development of a simple, low-cost, and eco-friendly stand-alone 3D microfluidic chemical sensing platform capable of colorimetric and biochemical analyses at the same time. The microfluidic cellulose microfiber (μCM) chip was prototyped by injecting 10% CM mixtures on computer numeric control (CNC)-milled substrates. We show that the μCM chip has a 3-fold faster flow rate than conventional microfluidic paper-based analytical devices and is a recyclable platform that could perform basic microfluidic experiments.
