E-IDEA for adaptive molecular sensing.
(a) The bending of a bare silica fiber in air with different electrode gaps increasing from with a step. The fiber length from the fixation point to the end is ; (b) the bending of a bare fiber in a mixture of solvent upon addition of silane, the formation of a positively charged self-assembled monolayer will decrease the overall charge; (c) the bending of the polymer-coated fiber at different acidic values; and (d) the bending of a polymer-coated fiber in water with a of 6.5 with electrode gaps decreasing from with a step.
(a) The adsorption of a negatively charged silica nanoparticle on a polycarbonate-coated fiber in water will change the direction of the bending in an electric field. The fiber length is , and the gap distance is , (b) The bending of HCl treated polycarbonate-coated fiber in air after treatment with solution for (curve 1), (curve 2), (curve 3), and (curve 4), (c) The optical micrographs indicate the contact angles of a polycarbonate coated fiber and a fiber treated with concentrated hydrogen chloride, (d) The effective surface charge density on a polymer coated fiber derived from the data shown in Fig. 1(c) .
