Abstract

The invention provides a droplet control detector and a working method thereof, and belongs to the technical field of microfluidics. The droplet control detector comprises: a light source; a first electrode and a second electrode, wherein an electric field for driving a droplet to move is formed between the first electrode and the second electrode; the droplet positioned at the light emitting sideof the light source, wherein the the electric field between the first electrode and the second electrode drives the droplet to move when an electrical signal is applied to the first electrode and thesecond electrode; a photodetection structure capable of detecting lights emitted by the light source and reflected by the droplet and obtaining droplet information according to the detection result;and a processing circuit used for controlling the electric signal applied to the first electrode and the second electrode according to the droplet information. The droplet control detector can realizehighly-effective and accurate droplet control.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a droplet control detection device and a working method thereof. Background technique [0002] Microfluidics (Microfluidics) refers to the science and technology involved in the use of micropipes (tens to hundreds of microns in size) to process or manipulate tiny fluids (nanoliters to attic liters in volume). , fluid physics, microelectronics, new materials, emerging interdisciplinary disciplines of biology and biomedical engineering. Because of the characteristics of miniaturization and integration, microfluidic devices are usually called microfluidic chips, also known as lab on a chip (Lab on a Chip) and micro-Total Analytical System (micro-Total Analytical System). The early concept of microfluidics can be traced back to the gas chromatograph produced on silicon wafers by photolithography in the 1870s, and then developed into microfluidic capillary electrophoresis and m...
