Abstract
This invention relates to the improvement of arrays of porous polymer pads on solid supports used in biological assays. The invention involves freeze drying the porous polymer pads to increase pore size. The increased pore size results in an enhanced ability of the porous polymer pads to bind specific binding substances such as DNA, RNA and polypeptides.
