The invention provides a universal magnetic force micromanipulation
system and method for gas and liquid. The
system comprises a
magnetic probe, a gas-liquid isolation probe frame, a probe frame clamping and levelness adjustment frame, a
laser, a photosensitive
position sensor, XYZ nanometer and micron
electrical control displacement stages and a
feedback controller. The gas-liquid isolation probe frame can effectively isolate air and liquid during working under a liquid-phase environment to guarantee a
working environment to be fully liquid-phase; the probe frame clamping and levelness adjustment frame can realize stable clamping and levelness adjustment of the probe frame; the XYZ nanometer and micron
electrical control displacement stages and the
feedback controller are used for changing a position of a sample to realize morphological and
magnetic imaging of the sample. The universal magnetic force micromanipulation
system and method for gas and liquid can realize morphological and
magnetic domain distribution observation, analysis and manipulation of magnetic samples under gas-phase and liquid-phase environments, and are applicable to various
biological materials and magnetic materials. The
system structure is simple, the technique is easy to realize and the system can be widely applied in fields of biomedical and material tests.
