We present a new method to increase nano‐particle migration rate in bubble stretching‐based technique. Vibration created by the inflation and shrinking process of bubbles is used. Process parameters can be adjusted to increase the probability of collision between the nano‐particles and the bubble wall. In effect, particles sufficiently migrate to the bubble wall, increasing both particle migration rate and dispersion ratio. Our measurement show that: (1) particle diameter, initial bubble radius, and initial bubble pressure strongly influence the migration of particles; (2) with appropriate parameters, nano‐particles can quickly and efficiently migrate to the bubble wall through this new method. © 2011 Wiley Periodicals, Inc.
