Monolithic supports are a novel generation of stationary phases that can be used for liquid and gas chromatography, capillary electrochromatography, bioconversions, as well as supports for solid phase synthesis. In contrast to individual particles packed into chromatographic columns, monolithic supports are cast as continuous homogeneous phases. They provide high rates of mass transfer at lower pressure drops and enable much faster separations. In addition to the speed, the nature of the pores allows easy permeability for large molecules. Monolithic supports are thus the method of choice for the separation of proteins, oligonucleotides, and nanoparticles such as pDNA and viruses. In this article we review the application of the monlithic columns to bioaffinity chromatography.
