Disclosed herein is a coupling apparatus for a wiper arm, which can provide firm coupling between a wiper blade and the wiper arm. The coupling apparatus comprises a blade coupling part provided to the wiper blade and including front and rear plates and having an opening defined at upper portions of the front and rear plates and a support shaft having a rectilinear plane formed at either side of the support shaft, and a wiper arm coupling part integrally formed at one end with the wiper arm and including a slant insertion mechanism to cause the wiper arm to be slantly inserted onto the support shaft and to hold the support shaft so as not to be separated from the slant insertion mechanism by changing an inclination of the wiper arm after the wiper arm is inserted onto the support shaft.

Provided is a method of separating particles, the method comprising: forming a first chamber and a second chamber separated by an interface with a pore, wherein the first and second chambers have electrodes with different polarities; placing particles to which a target biomolecule is bound from particles to which the target biomolecule is not bound in the first chamber; applying a voltage which has the same polarity as that of the target biomolecule to the electrode of the first chamber, and a voltage which has an opposite charge to that of the target biomolecule to the electrode of the second chamber; and translocating only the particles to which the target biomolecule is bound from the first chamber to the second chamber through the pore. Conventionally, the size of a pore is used to separate biomolecules. However, effective separation is difficult to achieve because the manufacture of a pore with a diameter of less than 10 nm, small enough to separate biomolecule, is not easy. Therefore, signal separation and data analysis must be required. However, in the present method, physical movement induced by the charge of biomolecules is used to effectively separate the biomolecules, thus obtaining a high signal to noise ratio. As a result, additional data analysis is not required.
