Abstract: In one aspect, a method of processing a cell is disclosed, which includes passing a cell through a pore of a membrane comprising a plurality of pores while exposing the cell to an agent so as to cause a change in the cell, thereby allowing said agent to enter the cell, where each of said pores extends from an input opening to an output opening and has at least one cross-sectional dimension, and in many embodiments a maximum cross-sectional dimension, less than a diameter of said cell. For example, at least one cross-sectional dimension of the pore, and in many embodiment the maximum cross-sectional dimension of the pore, can be less than about 40 microns, or less than about 30 microns, or less than about 20 microns, or less than about 15 microns, or less than about 10 microns.
