Which risk increases as inlet Reynold’s number approximates the limit for a microfluidic bioanalysis chip?

A)Onset of inertial cavitation events
B)Transition to transient turbulent flow
C)Complete diffusion-dominant analyte transport
D)Equilibrium concentration across the outlet

💡 Explanation

A higher Reynolds number means inertial forces are dominant at microscale inlet; therefore, rather than diffusion dominating, a transition to turbulent regimes happens because increased inertia triggers instabilities rather than maintaining laminar flow.
