    摘要: The present disclosure relates to a bio-detection chip and a detection method associated therewith. The bio-detection chip includes an upper substrate, a lower substrate, a reference electrode, a driving electrode, and a first dielectric layer, a first hydrophobic layer, a second hydrophobic layer and a second dielectric layer disposed successively between the reference electrode and the driving electrode. The bio-detection chip further includes a plurality of micro-capsules arranged between the first hydrophobic layer and the second hydrophobic layer. Each micro-capsule encapsulates a plurality of charged microspheres, and surfaces of the charged microspheres have a first biomolecule for specifically binding with a second biomolecule that enters the bio-detection chip so as to give rise to a color change. The charged microspheres move close to the upper substrate when a voltage is applied between the reference electrode and the driving electrode. As such, a result of biomolecule detection may be observed intuitively.

    摘要: A chip, a detection system and a gene sequencing method are provided. When the chip is used for gene sequencing, sample genes and reversible terminating nucleotides are added into micropores and matched therein to release hydrogen ions such that a Nernst potential is induced on an ion-sensitive film surface, and a voltage is applied to the transparent electrode layer to generate an electric field, thereby controlling the switching layer to change its state, and then a base type of the genes is determined based on a type of reversible terminating nucleotide corresponding to information of light emitted from the switching layer upon changes in the state of the switching layer, thereby gene sequencing is achieved.
