Patent ID: 7516714

Claim:
An immobilizing device comprising: a vibrating element for vibrating a solution or a solvent containing at least one sample, to form prongs of the solution or the solvent; and a charging device which is a separate unit from the vibrating element and disposed above the vibrating element with a spacing between the charging device and the vibrating element, the charging device being configured to contact the solution or the solvent, and to electrically charge the solution or the solvent in the prongs formed by the vibration of the vibrating element, wherein the charging device and the vibrating element are operated simultaneously to atomize the solution or the solvent by utilizing electrical charge concentration toward the prongs of the solution or the solvent formed by the vibration of the vibrating element into minute particulate substances whose activities and functionalities are kept, the device further comprises supporting means for supporting a substrate, disposed apart from the vibrating element, on which said charged minute particulate substances are deposited electrostatic forces, and said vibrating element comprises spreading means for spreading out said solution or solvent as a thin layer on the vibrating element.
