    Abstract: A layered, microfluidic array is disclosed. The array has a first layer with a culture channels extending in a first longitudinal direction. Each culture channel includes multiple traps that entrap cell or tissue samples. The array also has a second layer with microfluidic channels extending in a second longitudinal direction that is orthogonal the first longitudinal direction. A third layer, disposed between the first layer and the second layer, has pores arranged within the third layer such that each nest is vertically stacked above, and fluidly connected with, a corresponding culture chamber in the first layer.
