Sol-gel chip using porous substrate for entrapping small molecules and screening method of small molecules specific material using thereof

Abstract

There is provided a sol-gel chip using a porous substrate for entrapping small molecules and a method for screening a small molecule-specific material using the same, and more particularly, a porous substrate sol-gel chip characterized in that a sol-gel composition for entrapping small molecules is spotted on a surface of the porous substrate, a method for manufacturing the porous substrate sol-gel chip for entrapping small molecules, and a method for screening a material specifically binding to the small molecules using the porous substrate sol-gel chip for entrapping small molecules. According to the present invention, the small molecules can be effectively entrapped in the chip and the inflow of aptamers can be maintained as compared with the existing methods and thus aptamers specific to an extensive range of small molecules can be more easily selected.
