specific Embodiment
[0036]In the embodiment of the present invention, rat pheochromoma cells were selected, and the frequency of the micro-nano piezoelectric bulk acoustic wave resonator 1 used was 1.58 GHz. Such as figure 1 It is a structural diagram of the resonator 1 used in this embodiment, which includes a Bragg reflection layer 2, a bottom electrode 3, a top electrode 5 and a piezoelectric material 4. In the embodiment, the piezoelectric material is aluminum nitride material but not limited to this material.
[0037] The signal excitation system of the resonator in this embodiment is as figure 2 shown in . A sinusoidal signal with a frequency of 1.58 GHz is generated by the signal generator 6. After the signal is amplified by the power amplifier 7, it is input into the resonator 1; the regulated power supply 8 supplies power to the power amplifier 7. In this embodiment, the power is set as follows: the power of the AC signal after passing through the power amplifier is 300mW, 400mW, 500...
