Paper Abstract

Micro- and Nano-fabricated membrane sieves have a great potential in molecular separation applications by giving more precise structural and pattern control of shapes. This limitation can be addressed by a class of ultrathin membranes for molecular separations in solutions. Micromachining methods facilitate the accomplishing nanostructures to be used for separation of collections of particles. It makes possible to fabricate nanosieves having a thickness on the order of or even smaller than the diameter of the nanohole [1-2]. However, membrane fragility and complex fabrication have prevented the use of ultrathin membranes for molecular separations [3-4]. Furthermore, it is difficult to control the holes in nanoscale dimensions precisely and uniformly for mass production. Even though there are few reports on the size control of nanopores of the membrane nanosieves, it is necessary to do research on the precise and reliable size control of nanopores for mass production of biosensors or biochips.
