Create a technical diagram of a lab-on-a-chip microfluidic device for cell sorting: PDMS/glass hybrid chip fabrication, inlet ports for sample and sheath fluid, hydrodynamic focusing channel (width 50μm), laser interrogation zone (488nm excitation, forward scatter and fluorescence detection), piezoelectric actuator for deflection-based sorting into collection and waste channels. Show Reynolds number annotation (Re < 1, laminar flow), channel cross-section dimensions, and sorting decision logic. Include bright-field image of sorted droplets.
