“…Poly(acrylic acid-co-methylmethacrylate) membranes superfi cially modifi ed by the deposition of cholesterol-imprinted methacrylic acid nanospheres have been produced to develop a device for extracorporeal affi nity adsorption for atherosclerosis treatment [77]. Composite membranes, obtained by self-assembled multilayer of chitosan microspheres and PAA (poly(acrylic acid)) onto charged surface of polyacrylonitrile (PAN) membranes, have been used for wastewater treatment [78]. Th e layer-by-layer self-assembled deposition of chitosan microspheres was proposed as a new approach to functionalize membranes with high adsorption capability for metal ions such as copper ions.…”

High-precision, selective and effi cient systems are strongly demanded in all productive sectors, including chemical manufacturing, pharmaceutical, medical treatment, food, energy, diagnostic, analytical tools. Precision separation, conversion, formulation at molecular level may rely on various mechanisms and properties, such as molecular sieving, electrical charge, chemical solubility, molecular recognition. Membrane operation can promote mass transport, separation, conversion, formulation on the basis of the mentioned mechanisms. Biomimic and biohybrid funtionalised membranes are particularly suitable for separations based on molecular recognition.Membranes can be formed by polymers or monolythes bearing the (biomimic) recognition sites. In alternative, biomimic, biomolecules and recognition sites can be loaded on a previously formed membrane support. In such cases, surface functionalization methods can improve the loading effi ciency. Molecularly imprinted membranes; membranes bearing affi nity ligands (Antigen-Antibody, avidin/-ligand, DNA-protein, sugar-lectin, RNA-ribosome,…); membranes functionalized with zeolite and nanoparticles; membranes with immobilized enantioselective enzyme for kinetic resolutions, are among examples of selective and effi cient operations driven by molecular recognition. Th is is the mechanism by means of which molecules are able to identify each other using non-covalent -(hydrogen bonding, metal coordination, hydrophobic forces, van der Waals forces, π-π interactions and electrostatic eff ects) and covalent interactions.

“…Compared with the suspension polymerization and water/oil (W/O) emulsion crosslinking technique used to prepare magnetic adsorbents, the layer‐by‐layer (LbL) self‐assembly technique is a simple and environmentally friendly method of depositing functional polymers onto magnetic cores via alternative electrostatic coating of oppositely charged polyelectrolytes. Moreover, the thickness and the surface properties of multilayer deposition on the magnetic cores can be tunable by the LbL assembly technique without use of expensive equipment, and different types of bio‐degradable or biocompatible polymers can be used directly as polyelectrolytes for chemical deposition …”

A novel magnetic adsorbent alginate/polyethyleneimine (ALG/PEI)n/MN was developed for removal of anionic dyes from aqueous solution in this study. (ALG/PEI)n/MN was prepared by depositing ALG/PEI multi‐layers onto amine‐modified Fe3O4 microspheres through layer‐by‐layer method. The morphologies and structures of the adsorbent were characterized by scanning electron microscopy, X‐ray diffractometer, and Fourier transform infrared spectrometer, respectively, and its performance in adsorption of anionic dye (acid orange 10, AO10) under varied experimental conditions were also investigated. The results revealed that the uptake capacity of AO10 by (ALG/PEI)n/MN increased with the number of coated (ALG/PEI) bilayer on the adsorbents, and the maximum adsorption capacity for AO10 by (ALG/PEI)4MN was 246.3 mg g−1 at 25 °C. The adsorption process was exothermic and well described by the pseudo‐second order kinetic model and the Langmuir isothermal model. Moreover, (ALG/PEI)4/MN showed good reusability and excellent magnetic separability. All the results demonstrate that (ALG/PEI)4/MN is a potential recyclable adsorbent for removal of anionic dyes from wastewater. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 45876.
