This shadowgraph video shows protein modified silica nanoparticles falling after inversion of the hourglass-inspired microfluidic device. The driving buoyancy force behind the plume is gravity acting on the higher density of the particles temporarily suspended within a fluid. In the particle fall, we observe mushroom-shaped spikes of the heavier fluid growing into the lighter fluid, which follow the evolution of Raleigh Taylor instabilities. Ultimately, this device is intended to be used for infectious disease diagnostics.
