“…Antibiofilm surfaces can mainly be divided into antifouling surfaces and antibacterial ones. The former prevents bacterial attachment onto the surfaces while the latter kills bacteria on the surfaces (Xu et al, 2005;Li et al, 2018). Coating agents and paints such as silver, titanium oxide, grapheme, arsenic, mercury oxide, copper oxide, and zinc oxide nanoparticles have been developed and used effectively as antifoulants (Kuang et al, 2018).…”

Bacterial biofilms are complex surface attached communities of bacteria held together by self-produced polymer matrixs mainly composed of polysaccharides, secreted proteins, and extracellular DNAs. Bacterial biofilm formation is a complex process and can be described in five main phases: (i) reversible attachment phase, where bacteria non-specifically attach to surfaces; (ii) irreversible attachment phase, which involves interaction between bacterial cells and a surface using bacterial adhesins such as fimbriae and lipopolysaccharide (LPS); (iii) production of extracellular polymeric substances (EPS) by the resident bacterial cells; (iv) biofilm maturation phase, in which bacterial cells synthesize and release signaling molecules to sense the presence of each other, conducing to the formation of microcolony and maturation of biofilms; and (v) dispersal/detachment phase, where the bacterial cells depart biofilms and comeback to independent planktonic lifestyle. Biofilm formation is detrimental in healthcare, drinking water distribution systems, food, and marine industries, etc. As a result, current studies have been focused toward control and prevention of biofilms. In an effort to get rid of harmful biofilms, various techniques and approaches have been employed that interfere with bacterial attachment, bacterial communication systems (quorum sensing, QS), and biofilm matrixs. Biofilms, however, also offer beneficial roles in a variety of fields including applications in plant protection, bioremediation, wastewater treatment, and corrosion inhibition amongst others. Development of beneficial biofilms can be promoted through manipulation of adhesion surfaces, QS and environmental conditions. This review describes the events involved in bacterial biofilm formation, lists the negative and positive aspects associated with bacterial biofilms, elaborates the main strategies currently used to regulate establishment of harmful bacterial biofilms as well as certain strategies employed to encourage formation of beneficial bacterial biofilms, and highlights the future perspectives of bacterial biofilms.

“…81 Thus, dual-function materials are being developed to integrate the advantages of various singlefunction materials into a single system. 82 To more effectively prevent the formation of biofilm, an ideal bioresponsive material should perform the following functions: (i) resist initial bacterial attachment; (ii) kill bacterial cells that crossed the antiadhesion barrier; and (iii) release dead bacteria or other debris from the material's surface. 83 To achieve these goals, researchers have attempted to develop bioresponsive materials by combining two or more functions.…”

The colonization of undesired bacteria on the surface of devices used in biomedical and clinical applications has become a persistent problem. Different types of single-function (cell resistance or bactericidal) bioresponsive materials have been developed to cope with this problem. Even though these materials meet the basic requirements of many biomedical and clinical applications, dual-function (cell resistance and biocidal) bioresponsive materials with superior design and function could be better suited for these applications. The past few years have witnessed the emergence of a new class of dual-function materials that can reversibly switch between cell-resistance and biocidal functions in response to external stimuli. These materials are finding increased applications in biomedical devices, tissue engineering, and drug-delivery systems. This review highlights the recent advances in design, structure, and fabrication of dualfunction bioresponsive materials and discusses translational challenges and future prospects for research involving these materials.

“…Moreover, many issues (decrease in filtration efficiency, increase in the energy consumption, deterioration in water quality, acceleration in membrane aging, etc.) are brought out with the adhesion and accumulation of organic, biological and colloidal substances on the membrane surface or even inside membrane pores [8,9]. Worst still, it is proverbially difficult to prevent or eliminate.…”

Dual antifouling and antibacterial polysulfone(PSf)/polyethersulfone(PES) hybrid membranes were developed by the synergy of capsaicin-mimic N-(5-methyl acrylamide-2,3,4 hydroxy benzyl) acrylamide (AMTHBA) and vinyl triethylene (b-methoxy ethoxy) silane (VTMES). First, AMTHBA as a natural antimicrobial agent was incorporated into a casting solution via "microwave-assistance (MWA) in situ polymerization-blending" process to construct a hydroxyl-rich environment. Then, VTMES crosslinked to a hydroxyl-rich polymer matrix via hydrolytic condensation, and the influence of VTMES content on the hybrid membrane properties was systematically investigated. When the VTMES added amount was 1.0 wt %, the hybrid membrane achieved an optimal separation performance including a steady-state humic acid (HA) (5 mg/L) permeation flux of 326 L·m −2 ·h −1 and a rejection percentage of 97%. The antibacterial tests revealed that the hybrid membranes exhibited sustained bactericidal activity and effective inhibition of bacterial adhesion. Besides, the dual-functional membranes were clean as new after two-cycles filtration (with a cleaning efficiency of~90%), indicating that the network silicone film on the surface benefits the foulant repellence. Hopefully, the dual-functional membranes constructed in this study can be applicable to the pretreatment stage of water treatment.Polymers 2020, 12, 412 2 of 17 attachment of organic fouling and bacteria; (ii) bactericidal membranes for killing attached bacteria and preventing the formation of viable biofilm, which is principally against biofouling; and (iii) dual-functional bactericidal membranes for reducing both organic fouling and biofouling [13][14][15][16]. Among these, dual-functional bactericidal modification combining two strategies into one system is considered an ideal method. For example, Zhang et al.[17] designed a dual-functional antibacterial surface with a two-step surface modification strategy, aiming to acquire the properties of fouling resistance and antibacterial performance. Besides, Xie et al. [18] co-deposited polydopamine (PDA) and a zwitterionic polymer onto a polyethersulfone (PES) substrate and then immersed the surface in a AgNO 3 solution, leading to satisfactory antibacterial and antibiofouling properties. More recently, Wu et al. [19] synthesized a bifunctional membrane by incorporating silver-polydopamine nanohybrid (Ag-PDA) nanocomposites in a polysulfone membrane matrix. These results indicated the obvious advantages of dual functionality. However, due to the absence of strong bonding with surrounding polymers, active particles can be gradually leached out during operation, which could deteriorate the membrane antifouling efficiency [20]. In addition, the release of additional agents may have some potential impacts on the environment and human health [21].Capsaicin-mimic materials used as natural antifungal and antibacterial agents exhibit strong inhibition effects on various microbes and have been widely applied to resist marine or biomedical bacterial attachmen...
