Downstream processing (DSP) for purification can become a significant bottleneck in the production of novel biotherapeutics, such as viral vectors and vaccines (viral or DNA). Although different techniques can be used for the purification of large molecules and particles, liquid chromatography is the preferred method as it achieves the purity required by regulatory agencies. Despite the popularity of conventional chromatographic media, the diffusional mass transfer of large molecules and relatively small pore size remain limiting factors for the efficient separation of large biomolecules and particles.
