Roll-to-Roll Shrink-Induced Superhydrophobic Surfaces for Enhanced Point-of-Care Detection in Urine

Superhydrophobic (SH) features have been created in hard plastic by depositing metal on shrink film. These features are scaled up for roll-to-roll (R2R) manufacturing. Additionally, the SH surfaces enhance detection for point-of-care (POC) due to the concentrating effect during sample evaporation. SH surfaces are also compatible with bodily fluids such as urine, enabling protein detection in urine in the pre-eclampsia range for pregnant women.
