Abstract
The grafting of zwitterionic molecules onto solid surfaces is an important tool for decreasing the unwanted adsorption of biomolecules, such as proteins, bacteria, and cells. This has been achieved through various approaches, such as zwitterionic monolayer/multilayer formation, surface-initiated polymerization of zwitterionic monomers, and grafting of presynthesized zwitterionic polymers. Recently, a coordination-driven approach to grafting zwitterionic polymers onto solid surfaces has been discovered to be an effective method because of its versatility and robustness. However, the bacterial adhesion resistance of zwitterionic polymer grafting has been explored using only one molecular weight, and the non-biofouling performance against other fouling organisms has remained unexamined. In this study, the characteristics of coordination-driven surface zwitteration are systematically investigated. Sulfobetaine (SB) polymers with three different molecular weights are synthesized and employed for surface grafting. Polydopamine is used as a surface primer, and SB polymers are grafted onto the surfaces via the formation of metal-mediated coordinate bonds. The effect of molecular weight on the grafting efficiency and non-biofouling performance is investigated via protein adsorption and marine diatom adhesion assays. The SB polymer with a high molecular weight is found to be crucial for achieving strong resistance to protein adsorption and marine fouling.

Abstract
Fouling of surfaces in prolonged contact with liquid often leads to detrimental alteration of material properties and performance. A wide range of factors which include mass transport, surface properties and surface interactions dictate whether foulants are able to adhere to a surface. Passive means of foulant rejection, such as the microscopic patterns, have been known to develop in nature. In this work, we investigate the anti-fouling behaviour of animal fur and its apparent passive resistance to fouling. We compare the fouling performance of several categories of natural and manufactured fibres, and present correlations between contamination susceptibility and physio-mechanical properties of the fibre and its environment. Lastly, we present a correlation between the fouling intensity of a fibre and the cumulative impact of multiple interacting factors declared in the form of a dimensionless group. Artificial and natural hair strands exhibit comparable anti-fouling behaviour in flow, however, the absence of flow improves the performance of some artificial fibres. Among the plethora of factors affecting the fouling of fur hair, the dimensionless groups we present herein provide the best demarcation between fibres of different origin.

Abstract
Bacteria can thrive in biofilms, which are intricately organized communities with cells encased in a self-secreted matrix of extracellular polymeric substances (EPS). Imposed hydrodynamic stresses can transform this active colloidal dispersion of bacteria and EPS into slender thread-like entities called streamers. In this perspective article, the reader is introduced to the world of such deformable 'bacteria-EPS' composites that are a subclass of the generic flow-induced colloidal structures. While bacterial streamers have been shown to form in a variety of hydrodynamic conditions (turbulent and creeping flows), its abiotic analogues have only been demonstrated in low Reynolds number (Re < 1) particle-laden polymeric flows. Streamers are relevant to a variety of situations ranging from natural formations in caves and river beds to clogging of biomedical devices and filtration membranes. A critical review of the relevant biophysical aspects of streamer formation phenomena and unique attributes of its material behavior are distilled to unveil five grand scientific challenges. The coupling between colloidal hydrodynamics, device geometry and streamer formation are highlighted.

Hydrodynamics and surface properties influence biofilm proliferation. Adv Colloid Interface Sci 2021; 288:102336.

Abstract
A biofilm is an interface-associated colloidal dispersion of bacterial cells and excreted polymers in which microorganisms find protection from their environment. Successful colonization of a surface by a bacterial community is typically a detriment to human health and property. Insight into the biofilm life-cycle provides clues on how their proliferation can be suppressed. In this review, we follow a cell through the cycle of attachment, growth, and departure from a colony. Among the abundance of factors that guide the three phases, we focus on hydrodynamics and stratum properties due to the synergistic effect such properties have on bacteria rejection and removal. Cell motion, whether facilitated by the environment via medium flow or self-actuated by use of an appendage, drastically improves the survivability of a bacterium. Once in the vicinity of a stratum, a single cell is exposed to near-surface interactions, such as van der Waals, electrostatic and specific interactions, similarly to any other colloidal particle. The success of the attachment and the potential for detachment is heavily influenced by surface properties such as material type and topography. The growth of the colony is similarly guided by mainstream flow and the convective transport throughout the biofilm. Beyond the growth phase, hydrodynamic traction forces on a biofilm can elicit strongly non-linear viscoelastic responses from the biofilm soft matter. As the colony exhausts the means of survival at a particular location, a set of trigger signals activates mechanisms of bacterial release, a life-cycle phase also facilitated by fluid flow. A review of biofilm-relevant hydrodynamics and startum properties provides insight into future research avenues.

Abstract
In the present work, high-thickness zwitterionic polymer brushes based on imidazolium salts were successfully grafted via a novel subsurface-initiated ring-opening metathesis polymerization (subsurface-initiated ROMP) from polydimethylsiloxane (PDMS), and their antifouling performance was evaluated in detail. First, an initiator-embedded PDMS was prepared via copolymerization of PDMS prepolymer and ROMP initiator, and then zwitterionic polymer brushes were grafted via subsurface-initiated ROMP from surface to subsurface of the PDMS due to the implanted ROMP initiator. Results from a series of characterization methods such as infrared spectroscopy, X-ray photoelectron spectroscopy, contact angle, and atomic force microscopy proved the zwitterionic polymer brushes' successful grafting. The grafting thickness of zwitterionic polymer brushes via subsurface-initiated ROMP can reach the micron scale, and the as-prepared zwitterionic polymer based surfaces showed good lubricating properties compared to traditional surface-initiated ROMP, which hints that polymer brushes can be grafted not only on the surface but also on the subsurface of PDMS. The protein adhesion test and biofouling assay of zwitterionic polymer brushes were tested in the laboratory, and the results indicated that the zwitterionic polymer-functionalized PDMS can effectively resist the adhesion of bovine serum albumin and algae (Porphyridium and Dunaliella) and has good anti-bacterial activity against both Escherichia coli and Staphylococcus aureus.

Abstract
Incorporating natural product antifoulants (NPAs) into coatings with controlled surface topography is considered a promising way to suppress marine fouling. However, the rapid leakage of NPAs and the relatively complicated process of constructing well-patterned topography remain unresolved problems for practical applications. In this work, capsaicin bonded to CoFe2O4/gelatin magnetic nanoparticles was mixed with a polydimethylsiloxane (PDMS)-based block copolymer. When applied together by a simple spray-coating method, these materials formed a film. The leakage of capsaicin was restrained by the chemical bonds with the CoFe2O4/gelatin nanospheres. The primary nanorough structure was constructed by the phase separation of the PDMS-based copolymer. The secondary nanorough structure was formed by the incorporation of capsaicin-loaded CoFe2O4/gelatin nanospheres, which were demonstrated to improve the orientation of the PDMS-based block copolymer chains. The combination of oriented nanotopography and nonleaking capsaicin endows the coating with enhanced, long-lasting antifouling ability.

Abstract
Novel photocurable ternary polymer networks were prepared by incorporating N-(4-hydroxy-3-methoxybenzyl)-acrylamide (HMBA) into a cross-linked thiol-ene network based on poly(ethylene glycol)diacrylate (PEGDA) and (mercaptopropyl)methylsiloxane homopolymers (MSHP). The ternary network materials displayed bactericidal activity against Escherichia coli and Staphylococcus aureus and reduced the attachment of marine organism Phaeodactylum tricornutum. Extensive soaking of the polymer networks in aqueous solution indicated that no active antibacterial component leached out of the materials, and thus the ternary thiol-ene coating killed the bacteria by surface contact. The surface structures of the polymer networks with varied content ratios were studied by sum frequency generation (SFG) vibrational spectroscopy. The results demonstrated that the PDMS Si-CH3 groups and mimic-capsaicine groups are predominantly present at the polymer-air interface of the coatings. Surface reorganization was apparent after polymers were placed in contact with D2O: the hydrophobic PDMS Si-CH3 groups left the surface and returned to the bulk of the polymer networks, and the hydrophilic PEG chains cover the polymer surfaces in D2O. The capasaicine methoxy groups are able to segregate to the surface in an aqueous environment, depending upon the ratio of HMBA/PEGDA. SFG measurements in situ showed that the antibacterial HMBA chains, rather than the nonfouling PEG, played a dominant role in mediating the antibiofouling performance in this particular polymer system.

Abstract
The generation of polymer brushes by surface-initiated controlled radical polymerization (SI-CRP) techniques has become a powerful approach to tailor the chemical and physical properties of interfaces and has given rise to great advances in surface and interface engineering. Polymer brushes are defined as thin polymer films in which the individual polymer chains are tethered by one chain end to a solid interface. Significant advances have been made over the past years in the field of polymer brushes. This includes novel developments in SI-CRP, as well as the emergence of novel applications such as catalysis, electronics, nanomaterial synthesis and biosensing. Additionally, polymer brushes prepared via SI-CRP have been utilized to modify the surface of novel substrates such as natural fibers, polymer nanofibers, mesoporous materials, graphene, viruses and protein nanoparticles. The last years have also seen exciting advances in the chemical and physical characterization of polymer brushes, as well as an ever increasing set of computational and simulation tools that allow understanding and predictions of these surface-grafted polymer architectures. The aim of this contribution is to provide a comprehensive review that critically assesses recent advances in the field and highlights the opportunities and challenges for future work.

Abstract
The underwater superoleophobic surfaces play a significant role in anti-oil contamination, marine antifouling, etc. Inspired by the Gecko's feet and its self-cleaning property, a hierarchical structure composed of poly (acrylic acid) gel micro-brushes is designed by the liquid-infused method. This surface exhibits underwater superoleophobicity with very low oil adhesion. It is then modified with stimuli-responsive polymer nano-brushes via surface-initiated atom transfer radical polymerization from the embedded initiator. The micro/nano-brush dual structural surfaces can switch the underwater oil adhesion between low and high while keeping the superoleophobicity. The antifouling properties against algae attachment under different mediums are also investigated to show a strong link between oleophobicity and antibiofouling property. The model surface will be very useful in directing the design of marine self-cleaning coatings to both living and non-living species.

Abstract
In this study, we report a facile and versatile approach to the formation of marine antifouling surface coatings. The approach consists of a combined coating of polydopamine (pDA) and tannic acid (TA) and subsequent immobilization of polyethylene glycol (PEG) on solid substrates. TA coating of a pDA-coated surface was carried out using iron(III) coordination chemistry, and PEG was immobilized on the TA-coated surface via hydrogen bond formation. Stainless steel and nylon were successfully modified by this approach, and the resulting substrates were used for marine antifouling applications, in which diatom adhesion was significantly inhibited. Advantageously, this approach allowed marine antifouling coatings to be prepared by a simple immersion process under environmentally friendly conditions.

Chemically switched friction nano-fibrillar surfaces (SiNWAs-PSPMA & SiNWAs-PMAA arrays) can be constructed by finely decorating ordered Si nanowire arrays with responsive polymer brushes. As expected, these surfaces sense humidity or pH smartly and show reversible friction switching, based on swelling and shrinking of the polymer brushes, which is successfully monitored by AFM in liquid media.

Abstract
Zwitterionic polymer brushes based on sulfobetaine vinylimidazole (pSBVI) were successfully grafted to silicon substrates by electrochemical surface-initiated atomic-transfer radical polymerization (e-SIATRP), and exhibited excellent anti-fouling activities because of the presence of the two bactericidal functional groups, imidazolium and sulfonate. Various characterization techniques, including atomic force microscopy, X-ray photoelectron spectroscopy and use of a quartz crystal microbalance, were employed to characterize the polymer brush-modified silicon substrates. Subsequently, the anti-bacterial and anti-biofouling activities of the polymer brush substrates were evaluated. The experimental results showed that the pSBVI effectively resisted the adhesion of Nannochloropsis maritima and showed good anti-bacterial activity against Escherichia coli. In addition, in comparison with poly(vinylimidazole) brush-modified substrates and the bare substrate, the pSBVI-based materials also exhibited excellent anti-adsorption performance against both bovine serum albumin and lysozyme.
