In the desorpttion of the nanowire suspension, spectromery nanowire suspension is placed in swimmers warm up routine for weight lifting volatile solution, and then ultrasonic waves are applied to separate the nanowire from the substrate, thereby forming nanowire suspension in a state in which the nanowire is mixed with the volatile solution. Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. Subsequently, in a vacuum state such as a device used in a general Maldi process, a substrate on which a nanowire and an adsorbed crystallized sample is placed, is irradiated with a laser to the nanowire spot to desorb and ionize a sample and simultaneously apply a voltage on the substrate.
