a Schematic of the experimental setup to determine the buoyant mass of nanoparticles using a cantilever-shaped suspended microchannel resonator (SMR). Particles flow through the channel from the sample reservoir (inlet) to the waste reservoir (outlet). The time points t1 to t5 represent the position of the nanoparticle as it flows through the channel. The plot shows a representative resonant frequency shift with time for the fundamental resonant mode. b Optical microscope top-view image of the U-shaped silicon dioxide SMR. A scanning electrode microscope image of the cantilever cross-section is shown in the inset
