MIL-101(Cr)PEDOT in THF dispersions (10 µL) were drop-cast onto IDEs based on indium tin oxide (ITO) on glass, both in the absence and presence of an applied alternating potential. In the absence of an E-field, but under mild heating (90 °C), the droplets dried and left the MIL-101(Cr)PEDOT randomly distributed on the IDE substrate in the area where the droplet was placed. Prior to drying, the MIL-101(Cr)PEDOT particles within the sessile drops exhibited random Brownian motion. For MIL-101(Cr)PEDOT samples prepared with an applied E-field, the random Brownian motion of the particles ceased once the E-field was switched on and the particles were observed to rapidly move to the interelectrode regions that bore higher E-field intensity, spreading across the rectangular interdigitated electrode region of the substrate. Concomitant resistive heating of the sample arose due to the applied potential, leading to rapid sample drying within several seconds and avoiding the need for additional heating. In contrast, it was observed that deposition of MIL-101(Cr) with an applied E-field did not cause the particles to move to the interelectrode region but led only to their accumulation on the electrodes upon applying an E-field. The applied E-field induces dipoles in the MIL-101(Cr) particles, which in turn interact not only with the E-field but also with each other via dipole-dipole attraction leading to the formation of weak particle chains (Figure ). However, the E-field also induces migration of ions in the electrical double layer on the ITO electrodes, generating fluid drag referred to as AC electroosmotic or AC electrohydrodynamic flow near the solid-liquid interface between the ITO electrodes and the dispersion. This electroosmotic flow disrupts the weak particle chaining but aids in the accumulation of the MIL-101(Cr) at the electrode edges. In contrast, MIL-101(Cr)PEDOT can be oriented and chained between the electrodes, creating a continuous percolating network spanning the inter-electrode gap. Under the optimized Efield conditions (300 kHz, 750 V/mm), MIL-101(Cr)PEDOT particles are immediately concentrated and aligned into chains between the ITO electrodes (Figure ). (Figure ). In comparison, when drop-cast without an applied E-field, the MIL-101(Cr)PEDOT particles randomly distribute on the IDE substrates (Figure ). Typically, when a particle suspension is exposed to a non-uniform AC field 𝐸𝐸, of a certain frequency 𝜔𝜔, the particles experience a dielectrophoretic (DEP) force 𝐹𝐹 𝐷𝐷𝐷𝐷𝐷𝐷 , given by the following equation:
