Prospects for the use of polymer-containing materials and sorbents for membrane ultrafiltration, sorption and concentration of nucleic acids from aqueous media. A review

Unlike antibiotics and heavy metals, nucleic acids exist in the aquatic environment as a part of prokaryotic eukaryotic microorganisms (bacteria, fungi, etc.) rather than free form. In this regard, most important primary stage sample preparation an object for quantitative analysis DNA RNA natural wastewaters includes membrane ultrafiltration aqueous sample, followed by its sorption preconcentration on solid phase carrier. The efficiency subsequent from largely depends material filters, membranes, sorbents. Polymeric materials are widely used due to their special properties: affinity polymers biological objects, ability create pores any required size, good mechanical properties resistance extraction captured. paper reviews 15-year-old scientific literature filtering, polymeric extract media preserve them. sorbents collecting concentrating liquid phase, well storing acids, covered. It has been found that is at relatively low concentration analyzed object, substance using commercially available kits, including cartridges. Sorption (solid-phase concentration) high analyte. main include cellulose derivatives (nitrocellulose, acetate, mixed nitrate–acetate, diethylaminoethylcellulose, polyethyleneiminocellulose), agarose, dextran, polyestersulfone, polycarbonate, fluoroplasts, polyacrylates polymethacrylates, polyaramids, polyamides, polyvinyl alcohol, polyaniline, polycaprolactone, polyacrylamide polymethacrylamide, polystyrene. Chitosan, modified magnetic particles coated with polydopamine, polyethyleneimine, polyvinylpyrrolidone, polystyrene, or polyamidoamine dendrimer considered promising further research field.
