  • Pipette based on surface charges
    Patent number: 11224872
    Abstract: A pipette based on surface charges includes a pipette body. A plurality of support rods are provided below the pipette body. Connecting rods are provided at the lower ends of two adjacent support rods. A substrate is provided between the connecting rods. A porous SiO2 coating is provided on the substrate. A hydrophobic molecule layer is provided on the surface coating by the vapor deposition method. A superamphiphobic surface is formed on the substrate by the surface coating and the hydrophobic molecule layer. The substrate and the surface coating are made of dielectric materials. A circular limit plate is provided above the pipette body. The pipette body, the support rods, the connecting rods and the limit plate are integrally formed, and are electrically non-conductive. An electrically conductive sliding rod is movably provided within the pipette body and the limit plate.
