▎ 摘  要

NOVELTY - Integrated detection chip comprises light-induced dielectrophoresis microfluidic chip (10). The light-induced dielectrophoresis microfluidic chip includes a first ITO glass, a first channel layer, and a second ITO glass coated with hydrogenated amorphous silicon on the surface. The first ITO glass is connected to the second ITO glass through the first channel layer. The first channel layer is provided with a first channel (121) and a second channel (122) connected to the first channel. The first ITO glass is provided with a first through hole for injecting cell samples, a second through hole for flowing out the waste liquid, and a third through hole for transferring bacterial species. USE - Integrated detection chip for yeast. ADVANTAGE - The integrated detection chip realizes the integrated separation and detection of fungi, and can realize rapid and accurate detection of fungi. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for performing integrated detection for yeast, which involves setting a static light pattern array at the intersection of the light-induced dielectrophoresis microfluidic chip and form virtual electrodes, injecting a sample solution at the entrance of the light-induced dielectrophoresis microfluidic chip, resetting a dynamic light pattern array at the intersection of the light-induced dielectrophoresis microfluidic chip, and move the selected yeast cells to the exit of the second channel, transferring yeast cells in the light-induced dielectrophoresis microfluidic chip to the third channel of the graphene transistor detection chip through the connecting tube and collecting graphene transistor signals, analyzing and processing to obtain bacterial characteristics. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of integrated detection chip.
