Abstract

The invention discloses a nano operating device with a pair of near-field optical tweezers and an AFM probe. The nano operating device comprises a microoperation microscope and a pair of optical-fiber probe type near-field optical tweezers. After the pair of optical-fiber probe type near-field optical tweezers is led into a sample chamber through a microoperation microscope sample chamber and an outside interface, the particles of the sample is subjected to the nano operation by using the coupling force effect generated by compounding. Integrating the advantages of both the laser near-field optical tweezers and the AFM system, the nano operating device can ensure that devices can be coupled and connected more easily, the system can be operated efficiently and flexibly and compounded easily to have higher resolution ratio and higher reliability, and the nano particles can be effectively caught for characteristic study. The nano operating device is a higher-precision operating tool used in the field of the nanotechnology.

Description

technical field [0001] The invention relates to a nano-manipulation device utilizing optical means, in particular to a nano-manipulation device of near-field optical tweezers and AFM probes. Background technique [0002] In recent years, an important trend in the development of natural science and engineering technology is to move towards miniaturization. Correspondingly, the operation technology at the micro-nano scale is becoming more and more important. In the field of biological research, when using a microscope to observe biological samples, cells or molecules will jump out of the field of view of the microscope due to temperature changes, and the operator must frequently adjust the microscope to correct the field of view. However, if optical tweezers are used to fix biological samples, it will The biological cells or molecules will be clamped, so that the operator can better observe the cells and molecules, thereby reducing the impact of environmental changes and makin...
