Functionalized cryogel monoliths for fast and selective separation of nucleic acids directly from crude lysate

The fast and selective separation of nucleic acids has been attractive recently because of their wide number of applications in the biomedical field such as the development of vaccines for infectious diseases, gene therapy, and diagnosis. Traditional approaches of nucleic acids separation are costlier, lengthy, and associated with possible denaturation because of the use of organic solvents in the elution step. Under this perspective, cryogels represent an attractive choice as a monolith stationary phase in column chromatography, which have proven efficient in recent chromatographic studies. Cryogels are the macroporous hydrogels with interconnecting properties between the pores. They allow the easy flow of large biomolecules with minimum mass transfer resistance. They are spongy in nature and possess good mechanical strength. Current article represents different developed functionalized cryogel monoliths for nucleic acids separation, their separation strategies, and challenges associated with further advancement in separation science.
