On Ejecting Colloids Against Capillarity from Sub-micrometer Openings: On-Demand Dielectrophoretic Nanoprinting

Complex pattern generation of 2D and 3D structures exceeding 145 000 dpi in resolution is demonstrated by a non‐contact, on‐demand, colloid ejection and printing method at atmospheric conditions. The method relies on the DC dielectrophoretic actuation of uncharged nanoparticles in colloidal suspensi...

Summary:Complex pattern generation of 2D and 3D structures exceeding 145 000 dpi in resolution is demonstrated by a non‐contact, on‐demand, colloid ejection and printing method at atmospheric conditions. The method relies on the DC dielectrophoretic actuation of uncharged nanoparticles in colloidal suspensions, driven by short DC voltage pulses, generating large localized electric field gradients in an orifice of O(100 nm).
