Traditionally\ insuperhydrophobic\ surfaces history,\ the\ focus has frequently settled\ onthe\ use\ of\ complex processing methodologies using nonbiodegradable and costly materials.\ In\ light\ of\ recent events\ onlab-on-paper\ emergence, there are now some efforts for\ the\ production\ ofsuperhydrophobicpaper\ but still with little\ development\ and confined to\ the\ fabrication\ of\ flat\ devices. This work gives a new look at\ the\ range\ of\ possible applications\ of\ bioinspired\ superhydrophobicpaper-based substrates, obtained using a straightforward surface modification with poly(hydroxybutyrate). As an end-of-proof\ ofthe\ possibility to create\ lab-on-chip portable\ devices,\ the\ patterning\ ofsuperhydrophobicpaper\ with different wettable shapes is shown with low-cost approaches. Furthermore, we suggest\ the\ use\ ofsuperhydrophobicpaper\ as an extremely low-cost material to design essential nonplanar\ labapparatus, including reservoirs for liquid storage and manipulation, funnels, tips for pipettes, or accordion-shaped substrates for liquid transport or mixing. Such\ devices\ take\ the\ advantage\ ofthe\ self-cleaning and extremely water resistance properties\ ofthe\ surfaces as well as\ the\ actions that may be done withpaper\ such as cut, glue, write, fold, warp, or burn.\ The\ obtained substrates showed lower propensity to adsorb proteins than\ the\ original\ paper, keptsuperhydrophobic\ character upon ethylene oxide sterilization and are\ disposable, suggesting that\ the\ developing\ devices\ could be especially adequate for use\ in\ contact with biological and hazardous materials.
