    摘要: The subject invention concerns methods for interrogating a surface using scanning ion conductance microscopy (SICM). In one embodiment, a method of the invention comprises the steps of: a) repeatedly bringing a SICM probe into proximity with the surface at discrete, spaced locations in a region of the surface and measuring surface height at each location; b) estimating surface roughness or other characteristic for the region based upon the surface height measurements; and c) repeatedly bringing the probe into proximity with the surface at discrete, spaced locations in the region, the number and location of which is based upon the estimated surface roughness or other characteristic in the region, and obtaining an image of the region with a resolution adapted to the surface roughness or other characteristic.

    摘要: The present invention is based on the realization that the bonds between a target molecule, or a target molecule attached to a particle, and a surface, can be ruptured by mechanically oscillating the surface at increasing amplitude, leading to detachment of the target molecule or particle from the surface. The required acceleration, and hence force, will depend on a variety of factors, including the mass of the molecule or particle, the nature of the bond to the surface and the geometric shape or size of the target molecule or particle. The present invention may therefore be used to separate or to size different target molecules, or to detect their presence.

    摘要: The subject invention pertains to a method for determining the affinity between binding partners, or a property of one of the binding partners dependent on the affinity, comprising the steps of: (i) contacting the binding partners, one of which is immobilised on a surface; (ii) oscillating the surface at increasing amplitude; and (iii) detecting a dissociation event. An analogous method can be used to separate a target analyte from a composition. The subject invention also pertains to an apparatus for determining the affinity between binding partners, and comprises: a surface (10) having one binding partner (16) immobilised thereon; means for oscillating the surface at increasing amplitude; and means (14, 15) for detecting a dissociation event.
