Microtexturing of the Conductive PEDOT:PSS Polymer for Superhydrophobic Organic Electrochemical Transistors
Figure 1
The device features hierarchically different scales in correspondence of which different functions are revealed. On a larger, millimetric scale the superhydrophobic substrate has the appearance of a continuous flat surface, where drops are repelled and solutions can be easily manipulated (a). On a mesoscale, a microstructure is revealed, that is the major attribute of the present biosensor device (b). The smallest unit of such a microstructure is the micropillar, comprising a silicon core and covered by a thin film of PEDOT:PSS and C4F8 polymer.
