Molecular imprinting (MI) represents a strategy to introduce a 'molecular memory' in a polymeric system obtaining materials with specific recognition properties. MI particles can be used as drug delivery systems providing a targeted release and thus reducing the side effects. The introduction of molecular recognition properties on a polymeric drug carrier represents a challenge in the development of targeted delivery systems to increase their efficiency. This review will summarize the limited number of drug delivery MI particles described in the literature along with an overview of potential solutions for a larger exploitation of MI particles as targeted drug delivery carriers. Molecularly imprinted drug carriers can be considered interesting candidates to significantly improve the efficiency of a controlled drug treatment.

“…Threedimensional recognition sites can be formed by the polymerisation of functional monomers with a cross-linking agent in the presence of a target molecule; the removal of target molecules from the polymer results in the cavities selectively rebinding the target molecule. 2,6 Biomolecules play signicant roles in food, biological, chemical and medical industries. 3 MIPs have some signicant advantages, including molecular recognition ability, high selectivity, easy preparation, relatively low cost, durability and good mechanical and thermal stability.…”

Molecularly imprinted cryogel cartridges for the specific filtration and rapid separation of interferon alpha

In this study, we synthesised specific filtration cartridges with selective recognition sites for target molecules and used them to separate interferon a-2b from aqueous solutions. We combined molecular imprinting technology with cryogel to achieve specific and rapid filtration of interferon a-2b through the macroporous structure of a cryogel network. Recombinant interferon a-2b-imprinted poly(2hydroxyethyl methacrylate-N-methacryloyl-L-tryptophan) P(HEMATrp)/a-2bIFN cryogels were synthesised via free-radical bulk polymerisation under partially frozen conditions. The interferon a-2b filtration conditions were subsequently optimised with respect to factors such as pH, initial concentration, temperature, centrifugation speed, salt concentration and type and the amount of precomplex incorporated. Selectivity experiments were conducted in respect to isoelectric point as well as size of the competitor proteins under both uncompetitive and competitive conditions. The relative selectivity coefficients of the specific filtration cartridge in respect to isoelectronic points for interferon/ IgG, interferon/HSA and interferon/insulin pairs were 3.72, 7.10 and 10.68 times greater than the coefficient of a non-imprinted [P(HEMATrp)] filtration cartridge, respectively. Similarly, the relative selectivity coefficients of the specific filtration cartridge in respect to competitor size for interferon/ lysozyme, interferon/myoglobin and interferon/carbonic anhydrase pairs were calculated as 7.58, 10.40 and 11.68 under uncompetitive conditions whereas those values under competitive conditions were calculated as 1.08, 1.05 and 1.34, respectively. The results indicated that specific filtration cartridges developed could repeatedly adsorb interferon a-2b with a short separation time without any significant decrease in the adsorption capacity even if competitive conditions were conducted. ; Tel: +90 222 335 0580 † Electronic supplementary information (ESI) available.
