Abstract: A detection device and a detection method for distinguishing types of particles in an aqueous solution are provided. The detection device includes a detection chip, a signal source and a processing device. The detection chip includes a substrate, a coplanar waveguide transmission line and a super-hydrophobic film mask. When a to-be-detected aqueous solution that contains to-be-detected particles is provided on the detection chip, the super-hydrophobic film mask of the detection chip can confine the to-be-detected aqueous solution in a detection area. The processing device controls the signal source to provide detection microwave signals with different detection frequencies, simultaneously measures a first output signal and a second output signal at the different detection frequencies to generate a to-be-detected absorption spectrum, and compares the to-be-detected absorption spectrum with historical absorption spectra, so as to determine types of the to-be-detected particles.
