Abstract
An ultrasonic manipulation apparatus has a plurality of ultrasonic wave oscillators arranged in two dimensions to trap, fix or move particles to an optional position in the solution or perform cell fusion by using a gradient force obtained by superposing one over another the gradient force fields generated by ultrasonic waves produced by a plurality of ultrasonic wave oscillators. The ultrasonic wave oscillators, functioning independently of one another, can emit ultrasonic waves with optional intensities and phases, and by using an external force produced by superposed gradient force fields generated by ultrasonic waves, particles are handled easily.
