Abstract
An apparatus and method are provided for preparing specimens of biological cells uniformly distributed over a substrate surface. The method comprises providing a suspension of biological cells in fluid, and then extracting biological target cells from the suspension to leave debris and contaminants behind. The extracted target cells are distributed over a substrate surface into a primary layer of cells coupled to the substrate surface with the remaining cells forming a secondary layer on top of the primary layer. The target cells forming the secondary layer are then removed to produce a substantially non-overlapping layer of target cells coupled to the substrate surface.
