Magnetic control system base on measurement of target molecule adsorption

A portable magnetic-control measurement system, comprising:

• a reaction container configured to fill a target suspension having a plurality of magnetic nanoparticles (MNPs);
• a programable magnetron measurement unit comprises:
• an opaque housing;
• a loading platform configured to place the reaction container;
• a light-emitting device configured to generate a directional light through the reaction container;
• a magnetic field generator disposed on opposite two sides of the loading platform, to generate an alternating magnetic field forced on the reaction container in an operating time, wherein the magnetic field generator includes a linkage base and an electromagnet device, and the electromagnet device is detachably assembled to the linkage base;
• a sensing device configured to detect a light intensity variance of the directional light through the reaction container in the operating time;
• a processor communicatively coupled to the loading platform, the light-emitting device, the magnetic field generator and the sensing device, to calculate a value and an efficiency of absorption of the target suspension;
• a display communicatively coupled to the processor, to display the value and the efficiency of absorption of the target suspension;
• and
• a programmable logic controller and a step motor, a ball screw connected to the linkage base, wherein the programmable logic controller is communicatively coupled to the processor and the step motor, to receive a voltage signal from the processor and to control the step motor to drive the ball screw for changing a distance between the reaction container and the electromagnet device in a first direction.
