The chip implements flow-focusing and T-junction geometries for controlled droplet pinch-off. The dispersed phase is fed through a central inlet and pinched by two side streams of the continuous phase, giving a narrow size distribution and stable monodispersity without empirical tuning.
Droplet size is set by nozzle geometry and the phase flow-rate ratio, spanning roughly 1 to 1000 µm. Glass and polymer builds cover typical tasks: encapsulation of cells, particles and active compounds, nanoparticle synthesis and sample preparation.
The chip serves drug delivery, nutraceuticals, flavors and cosmetics. A standard substrate format and three-inlet layout ensure compatibility with the LA-Pump S series and common fluidic hardware; a parallel-nozzle layout is available for scale-up.
