Abstract

Methods and apparatus for preparing a smear for cytopathology or other analysis. In a representative embodiment, cells of a sample are subjected to a dielectrophoretic force to segregate the cells into two or more zones of a surface. The particles are attached to the surface, thereby defining a “segregated smear”. The segregated smear is then fixed and stained for cytopathology analysis.
