← ScienceWhich outcome results when the Peltier effect induces rapid phase transition in microfluidic channels controlling reagent mixing?
A)Controlled droplet ejection✓
B)Uniform temperature distribution
C)Decreased reaction time
D)Increased background noise
💡 Explanation
Controlled droplet ejection occurs because rapid phase transition initiates localized pressure spikes, therefore resulting in droplets rather than continuous flow due to cavitation effects rather than bulk displacement.
