Abstract
In one embodiment, a particle-retrieval device in accordance with the present teachings includes a receiver tube, vacuum-flow providing means and particle-disengaging means. The receiver tube is in fluid communication with the vacuum-flow providing means such that when flow is introduced into the vacuum-flow providing means, a suction or vacuum flow is developed at an end of the receiver tube. The suction causes a particle to adhere to the end of the receiver. A particle is disengaged by discontinuing the suction and, advantageously, by wetting the engaged particle.
