title: Tunable, pulsatile chemical gradient generation via acoustically driven oscillating bubbles.
abstract: We present a novel concept of generating both static and pulsatile chemical gradients using acoustically activated bubbles designed in a ladder-like arrangement. Furthermore, by regulating the amplitude of the bubble oscillation, we demonstrate that the chemical gradient profiles can be effectively tuned.
