1. A method for determining a property of a particle, comprising:
oscillating a suspended microchannel at a frequency within 10% of a resonant frequency of the suspended microchannel;
flowing the particle in the suspended microchannel; and
determining an acoustic scattering signal of the suspended microchannel while the particle flows through the suspended microchannel, wherein determining the acoustic scattering signal comprises determining a node deviation, wherein the node deviation comprises a difference in the resonant frequency of the suspended microchannel when the particle is at a node location of the suspended microchannel and the resonant frequency of the suspended microchannel when the particle is not in the suspended microchannel.
