“…Since the SPR sensitivity depends on the distance of the binding event from the SPR active surface, the sensor response due to the polymer films was calibrated as reported earlier. [18,52] A 1 nm shift in the resonant wavelength corresponds to a change in protein surface coverage of ∼ 17.0 ng/cm 2 [18,53] . Polymer coating was performed using a DOPA-PCB polymer solution (2 mg/mL) followed by washing with PBS solution to establish a clear base line (flow rate: 50 μL/min).…”

“…The “graft from” method requires the pre-modification of a surface with initiators for polymerization, but it is easier to achieve a higher grafting density [17] . Using this method, PCB was grown on a glass surface via atom transfer radical polymerization (ATRP) [12] and on a gold surface via photoiniferter [18] polymerization. On the other hand, the “graft to” method is simple and easy to carry out.…”

It is highly desirable to develop a universal nonfouling coating via a simple one-step dip-coating method. Developing such a universal coating method for a hydrophilic polymer onto a variety of surfaces with hydrophobic and hydrophilic properties is very challenging. This work demonstrates a versatile and simple method to attach zwitterionic poly(carboxybetaine methacrylate) (PCB), one of the most hydrophilic polymers, onto both hydrophobic and hydrophilic surfaces to render them nonfouling. This is achieved by the coating of a catechol chain end carboxybetaine methacrylate polymer (DOPA-PCB) assisted by dopamine. The coating process was carried out in water. Water miscible solvents such as methanol and tetrahydrofuran (THF) are added to the coatings if surface wettability is an issue, as for certain hydrophobic surfaces. This versatile coating method was applied to several types of surfaces such as polypropylene (PP), polydimethyl siloxane (PDMS), Teflon, polystyrene (PS), polymethylmethacrylate (PMMA), polyvinyl chloride (PVC) and also on metal oxides such as silicon dioxide.

“…Amidst the various RDRP techniques, ATRP has been used in the vast majority of studies, presumably by virtue of its facile implementation in such heterogeneous systems. Nevertheless, the iniferter [304][305][306], RAFT [307][308][309][310][311] and NMP [130,312] methods have been demonstrated to work well, too. Importantly, the RDRP methods do not only allow to tailor anti-fouling zwitterionic polymer films, they also allow to functionalize them conveniently with reactive groups [268,270].…”

Abstract:The structures and synthesis of polyzwitterions ("polybetaines") are reviewed, emphasizing the literature of the past decade. Particular attention is given to the general challenges faced, and to successful strategies to obtain polymers with a true balance of permanent cationic and anionic groups, thus resulting in an overall zero charge. Also, the progress due to applying new methodologies from general polymer synthesis, such as controlled polymerization methods or the use of "click" chemical reactions is presented. Furthermore, the emerging topic of responsive ("smart") polyzwitterions is addressed. The considerations and critical discussions are illustrated by typical examples.

“…To immobilize pCBs onto a flat substrate, one method is to grow densely packed polymer brushes through controlled polymerization techniques with the 'graft-from' approach ( Figure 3), such as surface-initiated atom transfer radical polymerization (si-ATRP), [10,21] photoiniferter-mediated polymerization, [28,58] or nitroxide-mediated radical polymerization (NMP). [32] An alternative approach uses a so-called 'graft-to' method: directly coat surfaces with the prepared block or random co-polymers through covalent bonds or physical interaction ( Figure 3).…”

Zwitterionic polycarboxybetaine (pCB)-based materials have drawn special attention due to their outstanding properties of resisting proteins adsorption, biofilm formation and cell attachment on a variety of substrates and surfaces, reducing the uptake of pCB-coated nanosized materials, as well as providing the capability of further functionalization. Zwitterionic pCBs have been proven to be excellent choices for many applications, not only limited to the field of antifouling. This review will summarize the recent progress on the development of pCB materials and the understanding of the structure-function-property relationships of carboxybetaine materials.
