The invention discloses an integrated
dielectric representing device of micro-nano
biological particles and with
multiple modes, which comprises a
dielectric representing
chip (100), a
machine visual device (200), a main
control system (300), an actuating
signal generating device (400), a virtual
electrode projector (500) and a micro displacement worktable (600), wherein, the
dielectric representing
chip (100) is positioned on the micro displacement worktable (600) and between the
machine visual device (200) and the virtual
electrode projector (500) in the vertical direction; the
machine visual device (200) comprises an elevating table (230) that is controlled by the main
control system (300); the main
control system (300) obtains data from the machine visual device (200), and simultaneously sends a command
signal to the actuating
signal generating device (400) and the virtual
electrode projector (500). The integrated dielectric representing device of micro-nano
biological particles and with
multiple modes integrates a light-mode virtual electrode and a spiral body
electrode array, and by collecting a particle movement image in real time and detecting the
particle suspension height with automatic focusing, the method can all-roundly and precisely measure a
dielectric spectrum under three dielectric
electrophoresis modes, and can realize the dielectric characteristic diagnosis of severe diseases, with low cost, high precision and high efficiency.
