“…Fabrication methods used to build lab-on-a-chips systems are based on micro-electromechanical systems (MEMS) technology and include soft lithography, hot embossing, injection molding, laser micromachining, and photolithography as well as more recently introduced threedimensional printing techniques (Fiorini and Chiu, 2005;Dragone et al, 2013;Ertl et al, 2014). The fabrication method of choice is guided by multiple factors, including available infrastructure (technology and equipment), fabrication speed, cost (multi-use or disposable devices), desired feature size, as well as the preferred fabrication material.…”
