“…For hydrogels for which antibacterial properties are based on the light-triggered generation of ROS or [ 1 O 2 ], photosensitizers are usually included in the preparation mixture and embedded in the final 3D polymeric network, either by grafting them onto oligomeric backbone units [42], by covalently conjugating them with monomeric units during crosslink-ing [87] or by encapsulating them within the hydrogel crosslinked network [88]. Upon irradiation, such a hydrogel is thus able to generate ROS or [ 1…”

“…In the framework of using dyes as photosensitizers, Li et al studied the introduction of rose bengal (RB), a well-known dye and photosensitizer, into graphene oxide (GO) based-hydrogel matrix in order to benefit from a synergistic antibacterial effect of photothermal therapy and photodynamic therapy [ 42 ]. They described the development of a hybrid hydrogel based on GO modified with a β-cyclodextrin aldehyde (β-CD-DA), RB grafted on chitosan microspheres via covalent immobilization and poly(vinyl alcohol) (PVA), with the purpose of obtaining a biocompatible and antibacterial material for wound dressing applications…”

Nosocomial diseases are becoming a scourge in hospitals worldwide, and new multidrug-resistant microorganisms are appearing at the forefront, significantly increasing the number of deaths. Innovative solutions must emerge to prevent the imminent health crisis risk, and antibacterial hydrogels are one of them. In addition to this, for the past ten years, photochemistry has become an appealing green process attracting continuous attention from scientists in the scope of sustainable development, as it exhibits many advantages over other methods used in polymer chemistry. Therefore, the combination of antimicrobial hydrogels and light has become a matter of course to design innovative antimicrobial materials. In the present review, we focus on the use of photochemistry to highlight two categories of hydrogels: (a) antibacterial hydrogels synthesized via a free-radical photochemical crosslinking process and (b) chemical hydrogels with light-triggered antibacterial properties. Numerous examples of these new types of hydrogels are described, and some notions of photochemistry are introduced.

“…However, rising concerns about their cytotoxicity against mammalian cells oriented the research to more biocompatible materials such as carbon-based materials. With several of them showing interesting antibacterial properties such as graphite [31][32][33][34], graphene [35][36][37][38], and carbon nanotubes [39][40][41][42][43] to cite only a few of the latest references, carbon-based materials are definitely an interesting strategy to explore to keep surfaces bacteria-free or to reduce infection based on Antibiotic-Resistant Bacteria (Table 1).…”

antibiotic resistance in bacteria is a current threat causing an increasing number of infections of difficult clinical management. While the overuse and misuse of antibiotics are investigated to reduce them, the need for alternatives to approaches is rising. carbon-based materials shown recent moderate to high antibacterial properties and diamond, thanks to its superior mechanical, tribological, electrical, chemical and biological quality is a choice material to investigate for safe antibacterial films, coatings and particles. here, the antibacterial properties of diamond films, nanodiamonds, Dlc films and a comprehensive list of the composites developed from them are discussed along with a summary of the bacterial strains used and the most efficient composition and/or concentration discovered. in a later stage, the mechanisms of action and the parameters that are believed to influence them are discussed and finally, an overview of the biomedical and food industry applications is given.

Advancements in polymers have made significant contribution in diverse application‐oriented fields. The multidisciplinary application of polymers generates a range of strategies, which is applicable in a wide range of biomedicines. Polymeric compounds such as hydrogels have been explored globally as a potent biomaterial that can furnish essential attributes due to their three‐dimensional (3D) soft and highly hydrophilic polymeric network. These hydrogels have been used extensively in various applications due to their biocompatible, biodegradable, and biosorption nature. However, they have some limitations, owing to their soft nature, low mechanical properties, and unsatisfactory degradation profile. Therefore, there is a need to develop novel, stronger, and more durable hybrid hydrogels with enhanced biocompatible and multifunctional properties. The current review gives a broad spectrum of hybrid hydrogels with its importance and significance. Further, the review highlights the strategies of generation of hybrid hydrogels reinforced with nanomaterials, biomaterials, and nanobiocomposites along with their advantages and disadvantages. The review also features various applications of these hybrid hydrogels in the field of biomedicines, photocatalysis, agriculture, and food industry over the last 5 years. This review will give a comprehensive overview to researchers working in the field of hybrid hydrogels development.
