“…25,26 Polydopamine (PDA) has stimulated extensive research in the membrane surface functionalization for antifouling purpose. 27−29 Interestingly, PDA has been found to reduce Ag + ions to Ag and to synthesize Ag NPs in situ on different substrates without any other reducing agent.…”

Microbial attachment and biofilm formation on filtration membrane can greatly compromise its flux and separation efficiency. Here, a simple and facile approach has been developed to in situ generate silver nanoparticles (Ag NPs) on the thin film composite forward osmosis (TFC FO) membrane for sustainable antibiofouling performances. Mussel-inspired dopamine chemistry was applied to grow polydopamine coating on both surfaces of FO membranes, followed by the generation of Ag NPs upon a simple dip coating in silver nitrate aqueous solution. Furthermore, the Ag NPs deposited membranes had a long-term silver release profile with rechargability for multiple times upon their depletion, and exhibited strong sustainable bactericidal efficacy against Gram-negative bacteria and Grampositive bacteria. The Ag NPs had a controllable effect on the membrane performances including the water flux and reverse salt flux in the FO test mode. Our practicable antibacterial strategy may apply to other types of filtration membranes with diverse material surfaces and may pave a new way to achieve the sustainable membrane antibiofouling performance on a large scale.

“…The mussels' adhesive capacity may be attributed to the interface between the substrate surface and Mytilus edulis foot protein (Mefp). More and more investigations discovered that the Mefp abound various catecholic amino acid, including the dopamine (DA) and its derivative, which in favor of the high bonding or crosslinking ability of adhesives 13. Herein, a simple polydopamine (PDA) modification strategy, which is mussel‐inspired biomimetics, was established to enhance the stability and improve the photothermal performance of the BP NSs‐based codelivery platform.…”

“…Herein, a simple polydopamine (PDA) modification strategy, which is mussel‐inspired biomimetics, was established to enhance the stability and improve the photothermal performance of the BP NSs‐based codelivery platform. PDA, produced by the oxidative polymerization of DA under weakly alkaline conditions, has been employed as a promising coating in the biological field due to their excellent biocompatibility, biodegradation, and pH response at low pH values 13. PDA coating can form extraordinary adhesion on nearly any substrate surfaces and further couple secondary biopolymers with amines/thiols via Michael addition or Schiff base reactions 14.…”

Polydopamine‐Modified Black Phosphorous Nanocapsule with Enhanced Stability and Photothermal Performance for Tumor Multimodal Treatments

As a novel 2D material, black phosphorus (BP) nanosheets are considered as a promising candidate for drug delivery platform for synergistic chemo/photothermal therapy. However, the intrinsic instability of bare BP poses a challenge in its biomedical applications. To date, some strategies have been employed to prevent BP from rapid ambient degradation. Unfortunately, most of these strategies are not suitable for the drug delivery systems. Here, a simple polydopamine modification method is developed to enhance the stability and photothermal performance of bare BP nanosheets. Then, this nanocapsule is used as a multifunctional codelivery system for the targeted chemo, gene, and photothermal therapy against multidrug‐resistant cancer. The enhanced tumor therapy effect is demonstrated by both in vitro and in vivo studies.

“…The potential of more stable hydrophilic coatings to facilitate membrane cleaning is therefore still promising (Miller et al 2012). Moreover, polydopamine is amphoteric and differently charged in acidic and basic environments (Liu et al 2014), and the results suggest that surface charge affects the early attachment of biofouling on the feed spacer surface, since electrostatic interactions between surfaces and the charged outer layer of cell membranes of fouling organisms can play a role.…”

Biofouling is still a major challenge in the application of nanofiltration and reverse osmosis membranes. Here we present a platform approach for environmentally friendly biofouling control using a combination of a hydrogel-coated feed spacer and two-phase flow cleaning.Neutral (polyHEMA-co-PEG10MA), cationic (polyDMAEMA) and anionic (polySPMA) hydrogels have been successfully grafted onto polypropylene (PP) feed spacers via plasmamediated UV-polymerization. These coatings maintained their chemical stability after 7 days incubation in neutral (pH 7), acidic (pH 5) and basic (pH 9) environments. Anti-biofouling properties of these coatings were evaluated by E. coli attachment assay and nanofiltration experiments at a TMP of 600 kPag using tap water with additional nutrients as feed and by using optical coherence tomography. Especially the anionic polySPMA-coated PP feed spacer shows reduced attachment of E. coli and biofouling in the spacer-filled narrow channels resulting in delayed biofilm growth. Employing this highly hydrophilic coating during removal of biofouling by two-phase flow cleaning also showed enhanced cleaning efficiency, feed channel pressure drop and flux recoveries. The strong hydrophilic nature and the presence of negative charge on polySPMA are most probably responsible for the improved antifouling behavior. A combination of polySPMA-coated PP feed spacers and two-phase flow cleaning therefore is promising and an environmentally friendly approach to control biofouling in NF/RO systems employing spiral-wound membrane modules.3
