Column chromatography is a technique in which the substances to be separated are introduced onto the top of a column packed with an adsorbent, passed through the column at different rates that depend on the affinity of each substance for the adsorbent and for the solvent or solvent mixture, and...
As the crude mixture of the substances is passed through the chromatography column, substances with binding site for the immobilized substrate bind to the stationary phase, while all other substances is eluted in the void volume of the column. Once the other substances are eluted, the bound targe...

They fabricated carbon resistors on cantilever beams made of chromatography paper. Although they named their device a MEMS sensor, its size (~cm) is quite large compared to the ones made from Si which are micro-scale. An extension of this work was presented by Ren et al. [8]. They ...
