Abstract
The invention is directed to a method of contacting a biological sample with a solution, comprising the steps of moving a curved surface wetted with the solution in proximity to the biological sample whereby the distance separating the wetted curved surface and the biological sample is sufficient to form a moving liquid meniscus layer between the two. The invention is also directed to an apparatus for contacting a biological sample suspected of containing a biomarker with a solution, comprising a platform for supporting a microscope slide having a biological sample thereon; a translating cap having a curved lower surface positioned above the platform, the curved lower surface being in proximity to a biological sample when in operation; means for moving the translating cap back and forth over the biological sample; and means for applying and removing liquid to and from the cap.
