摘要
Apparatus and methods to improve the Boyden chamber used in cellular biological measurements, allowing quantitative optical microscopy of biological cells in situ without using fluorescent probes or optical staining. In the preferred embodiment, a thin porous membrane separating top and bottom reservoirs includes an array of precisely positioned micropores pores manufactured using a laser-based photo-machining (ablation) process. The membrane may be composed of polyethylene terephthalate (PET), polycarbonate, polyimide, polyether ether ketone (PEEK) or other appropriate material. The pores formed in the membrane may have diameters in the range of 1 to 15 microns and spaced apart at a distance ranging from 10 to 200 microns. A plurality of upper and lower reservoirs may be provided to form a multi-well plate. The invention finds application in a wide range of potential biological applications where Boyden chamber geometries are currently used including co-culture studies, tissue remodeling studies, cell polarity determinations, endocrine signaling, cell transport, cell permeability, cell invasion and chemotaxis assays.
