“…Hydrogels have been shown to have an adhesion property and to stimulate wound healing without the use of growth factors in in vivo investigations. Hydrogels containing photothermal Bi 2 S 3 NPs were first created for wound treatment; these hydrogels generated heat energy for bactericidal purposes when exposed to near-infrared (NIR) light (Zhou et al 2023 ). A NIR light catalyst (Bi 2 S 3 –S-nitrosothiol–acetylcholine (BSNA)) was developed in another work by converting • O 2 – into peroxynitrite in situ; this compound may increase bacteria’s sensitivity to ROS and heat, killing them at a relatively low temperature.…”

Bismuth (Bi) combinations have been utilized for the treatment of bacterial infections. In addition, these metal compounds are most frequently utilized for treating gastrointestinal diseases. Usually, Bi is found as bismuthinite (Bi sulfide), bismite (Bi oxide), and bismuthite (Bi carbonate). Newly, Bi nanoparticles (BiNP) were produced for CT imaging or photothermal treatment and nanocarriers for medicine transfer. Further benefits, such as increased biocompatibility and specific surface area, are also seen in regular-size BiNPs. Low toxicity and ecologically favorable attributes have generated interest in BiNPs for biomedical approaches. Moreover, BiNPs offer an option for treating multidrug-resistant (MDR) bacteria because they communicate directly with the bacterial cell wall, induce adaptive and inherent immune reactions, generate reactive oxygen compounds, limit biofilm production, and stimulate intracellular impacts. In addition, BiNPs in amalgamation with X-ray therapy as well as have the capability to treat MDR bacteria. BiNPs as photothermal agents can realize the actual antibacterial through continuous efforts of investigators in the near future. In this article, we summarized the properties of BiNPs, and different preparation methods, also reviewed the latest advances in the BiNPs’ performance and their therapeutic effects on various bacterial infections, such as Helicobacter pylori , Staphylococcus aureus , Pseudomonas aeruginosa , and Escherichia coli .

“…Hydrogels have gained interest in several applications, including drug delivery, tissue engineering, and surface coating, as shown in Table 1. Due to several kinds of hydrogels, they have unique properties, such as porosity, 28,29 swollen, 30 mechanical strength (e.g., stiffness, viscoelasticity, and permeability), 31 biocompatibility, biodegradability, and microorganisms sensing, which provide an advantage for versatile applications 3,32–34 . One important ability of hydrogels is increasingly interested in the impact on microorganisms, including bacterial growth, and antibacterial activity, which provide an advantage in biomedical and environmental applications.…”

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.

“…Bacterial infection is one of the most common problems in wound healing [109]. When a wound is infected, the bacteria will continue to slow down the inflammatory stage's healing process and may potentially cause complications [110]. Therefore, hydrogel dressings have good antibacterial properties and thus have important clinical significance [111].…”

One of the most advanced, promising, and commercially viable research issues in the world of hydrogel dressing is gaining functionality to achieve improved therapeutic impact or even intelligent wound repair. In addition to the merits of ordinary hydrogel dressings, functional hydrogel dressings can adjust their chemical/physical properties to satisfy different wound types, carry out the corresponding reactions to actively create a healing environment conducive to wound repair, and can also control drug release to provide a long-lasting benefit. Although a lot of in-depth research has been conducted over the last few decades, very few studies have been properly summarized. In order to give researchers a basic blueprint for designing functional hydrogel dressings and to motivate them to develop ever-more intelligent wound dressings, we summarized the development of functional hydrogel dressings in recent years, as well as the current situation and future trends, in light of their preparation mechanisms and functional effects.
