Hydrogels find diverse applications in manipulating bacteria, and serving purposes like elevation, maintenance, and elimination. Several factors of hydrogel have been studied in the benefits of antibacterial activity. Factors such as hydrogel stiffness and roughness gain significance in surface coating, influencing bacterial behavior. However, the intricate interplay of hydrogel stiffness, roughness, polymer types, and bacterial species necessitates further exploration. The choice of polymer is dictated by the specific objectives, particularly in antibacterial scenarios where polymers with positive charge, hydrophilicity, and acidity prove effective. These properties induce robust electrostatic and hydrophobic/hydrophilic interactions, along with pH‐induced cell membrane damage, collectively contributing to hindered bacterial adhesion and growth. Additionally, extracellular polymeric substances (EPS) emerge as pivotal influencers in bacterial adhesion and proliferation. EPS production alters bacterial surfaces, fostering connections between bacteria and facilitating biofilm formation. The hydrophobic nature of EPS further complicates bacterial interactions with surface materials, emphasizing the nuanced interplay of hydrophilic and hydrophobic forces in bacterial adhesion. Herein, this work article has reviewed the related study of each physical property related to antibacterial property on the surface of the hydrogel. Moreover, this work also illustrates applications of the antibacterial properties of hydrogel for medical and surface treatment, including wound healing, food packaging, and surface coating. Additionally, the bacteria growing on hydrogel for engineered living materials, have been updated in various applications.

“…The critical aspect in oil–water separation is to regulate the interfacial wettability. Materials with unique wetting properties, such as superoleophobic and superhydrophobic substances, are extensively employed to separate oil from water in recent decades. − These especially wettable membranes are broadly divided into “oil-removing” and “water-removing” according to the contrary oil and water affinities, i.e., superhydrophilic/underwater superoleophobic and superhydrophobic/superoleophilic . The superhydrophilic/underwater superoleophobic membrane shows superiority over the superhydrophobic/superoleophilic membrane in that the latter is easily contaminated by oil whereas the former could effectively prevent oil from contamination. , However, these synthesized membranes have underperformed in separating oil–water emulsions stabilized by surfactant because of the “size-sieving” effect, despite being able to effectively separate immiscible oil–water mixtures.…”

Due to the high oil spill incidence and industrial wastewater discharge including oil and emulsified oil, designing and synthesizing oil–water separation materials which can maintain stability under harsh environmental conditions with high separation efficiencies remains a great challenge. The present work developed an easy, green, cost-effective, and easily scaled-up approach for fabricating cellulose-based membranes. First, we coated polydopamine (PDA) onto fibers of filter membrane (FM). Then, the PDA-FM membrane was immersed into the mixed solution of poly(vinyl alcohol)/poly(acrylic acid) (PVA/PAA) and further thermally cross-linked at 150 °C to create a superhydrophilic/underwater superoleophobic membrane (PVA/PAA@PDA-FM) to separate oil/water mixtures. The simple thermally cross-linking process promotes multiple covalent chemical bonds generation between cellulose filter membrane, PAA, PDA, and PVA, endowing membranes with excellent stability and resistance to acidity, alkalinity, and salinity. The PVA/PAA@PDA-FM membrane not only demonstrates great separation performance (>99.8%) and great flux (>1000 L m–2 h–1) in oil–water immiscible mixtures but also maintains high separation efficiency under conditions of high acidity, alkalinity, and salinity. Additionally, the PVA/PAA@PDA-FM membrane exhibits excellent separation capacity in oil–water emulsions, which can maintain the >99.6% separation efficiency even after 40 cycles in harsh environments, showing outstanding reusability. Thus, due to the multiple cross-linked networks in the membrane, the excellent performance makes the PVA/PAA@PDA-FM membrane a good application prospect in water purification and oily wastewater treatment.

Membrane fouling remains a major challenge during oily wastewater purification, resulting in reduced water flux and separation efficiency. Zwitterionic polymers have been introduced to the PVDF membrane and shown their fouling resistance ability. However, most current zwitterions lack bactericidal effects and tend to be fouled by the attachment of bacteria and biofilm formation in long-term service. Herein, a synthetic zwitterionic poly(imidazolium), poly(ZIM-co-VTS), was introduced onto the PVDF membrane by co-assembly with polydopamine (PDA) and tetraethyl orthosilicate (TEOS) as a silica source. The in situ covalent bond can be formed between the catechol from PDA and silanol groups from both TEOS and imidazole-based polymers. Further, Fe3+ cross-linking contributes to the robust chemical stability of modified PVDF. The as-prepared coating exhibits superhydrophilicity and underwater superoleophobicity under harsh conditions (pH = 1 and 13), remaining high separation efficiency (>99%) toward various surfactant-stabilized oil-in-water emulsions without an apparent water flux (>1013 L m–2 h–1 bar–1) decline. More importantly, the cationic imidazolium in poly(ZIM-co-VTS) endues the excellent bacterial killing efficiency toward Staphylococcus aureus (4.5 log10 reduction) and Escherichia coli (4.7 log10 reduction). The zwitterionic poly(imidazolium)-modified PVDF exhibited long-term durability with anti-biofouling properties and was a promising candidate for practical oily wastewater remediation.
