Print-to-Print: A facile flexible multi-object patterning process using superhydrophobic films
Abstract: In this paper, we present a simple versatile printing-based method, referred to as Print-to-Print (P2P), to form multi-object micropatterns for potential biological applications, along with our recent efforts to deliver out-ofcleanroom microfabrication solutions to the general public. The P2P method employs only a commercially available solid-phase printer and reusable superhydrophobic films developed by us. The whole process does not involve any thermal or chemical treatment. Moreover, the non-contact nature of droplet transferring and printing steps can be highly advantageous for sensitive biological uses. Using the P2P process, a minimal feature resolution of 229μm has been successfully demonstrated. In addition, this approach has been applied to form biological micropatterning on various substrates as well as multi-object copatterns on the commonly used surfaces. Finally, the reusability of superhydrophobic substrates has also been illustrated.
