Detection system

By designing a mounting bracket and separators in the detection system to form a gas chamber, diamond is brought into contact with magnetic beads in the liquid sample. The magnetic properties of the liquid sample are then detected using NV color centers, solving the efficiency and accuracy problems of magnetic detection of liquid samples and achieving efficient and non-destructive magnetic imaging.

AI Technical Summary

Technical Problem

Existing technologies are insufficient for efficient and non-destructive magnetic detection of liquid samples, especially in terms of spatial resolution, field of view, and imaging speed.

Method used

A detection system was designed, which forms a gas chamber by setting a mounting bracket and a separator on a carrier. The NV color center in the diamond and the magnetic beads in the liquid sample are brought close together. By introducing gas, the carrier is deformed to achieve contact. Combined with a driving mechanism and an objective lens, the magnetic properties of the liquid sample can be detected.

Benefits of technology

It enables efficient and non-destructive magnetic detection of liquid samples, improves spatial resolution, field of view and imaging speed, and enhances the reliability and efficiency of the detection system.

Abstract

The application discloses a detection system, which comprises a carrier, a mounting frame, a separator, an objective lens and a diamond. The carrier is used for carrying a liquid sample, and the liquid sample comprises magnetic beads. The mounting frame is movable relative to the carrier, and the mounting frame is provided with a mounting space. The separator is arranged in the mounting space and separates the mounting space to form a first space and a second space. When the mounting frame is at a predetermined position, the carrier shields the first space to form a gas chamber. The gas chamber is used for introducing gas, and the gas chamber is used for accommodating the liquid sample and deforming the carrier when the gas is introduced. The objective lens is arranged in the second space and connected with the mounting frame. The diamond is arranged outside the gas chamber and used for contacting the carrier and detecting the liquid sample. At this time, the diamond and the liquid sample on the carrier are close to each other, and NV color centers in the diamond can be affected by the magnetic beads in the liquid sample, so that the magnetic detection of the liquid sample is realized.
