<p>Provided are a nanoporous membrane including a support; a first separation layer with a plurality of first nano-sized pores and a first matrix; and a second separation layer having a plurality of second pores respectively corresponding to the plurality of first pores of the first separation layer and a second matrix, and formed on the first separation layer, wherein a density of the plurality of the first pores and the second pores is equal to or greater than 1010/cm2, and a diameter of each of the second pores is less than that of the corresponding first pore, a process of fabricating the same, and a device for a controlled release of biopharmaceuticals including the nanoporous membrane. The device for a controlled release of biopharmaceuticals including the nanoporous membrane can release biopharmaceuticals at a constant rate for a long period of time regardless of the concentration of the biopharmaceuticals including in pharmaceuticals, and high flex and selectivity.</p> |
