ABSTRACT:
The present invention pertains to an apparatus for imaging an object, comprising a probe via which an assay component may be delivered; a sensor to detect ion current; and means for controlling the position of the probe relative to the object in response to the ion current. Such apparatus can be used to image live cells, without affecting them, in solution, e.g., using light, wherein the distance between probe and cell is less than the wavelength of light.
