3 Terms and Definitions

GB/T 21636-2008 define the following terms and definitions apply to this document. 3.1 Live cell samples livingcels In vitro culture or acute isolated cells. 3.2 Magnetic actuator tapping mode AFM magneticlightly-strikingmodeatomicforcemicroscope Use the back of an alternating magnetic field driven cantilever probe coated with magnetic film morphology and physical properties of the samples were detected tapping mode atomic force Micromirrors. 3.3 Magnetic cantilever magneticcantilever The back of the cantilever coated with magnetic film. 3.4 Amplitude attenuation magnitudeofamplitudedamping The ratio of the amplitude of the cantilever work and freedom amplitude.

4 Fundamentals

Atomic force microscopy (atomicforcemicroscope, AFM) using extremely sensitive to the weak force with the cantilever tip in the sample Scan the surface to obtain a product image. During scanning, the interaction force at the top of the tip and the sample surface of the outermost layer of atoms between the atoms Of the micro cantilever is deformed or changed constantly in motion, so the laser beam reflected by the smooth back of the cantilever onto a photodetector Position is constantly changing. AFM cantilever is detected by a photodetector state to obtain a sample morphology and forces, etc. information. AFM tapping mode magnetic drive is suitable for soft surface, biological samples and other non-destructive imaging, which uses a cross Varying magnetic field driving the back of the film is coated with a magnetic cantilever probes to a specific amplitude-frequency vibration, while the PZT scanner
