Antibiotic resistance is one of the greatest threats to global health and food security today. It becomes increasingly difficult to treat infectious disorders because antibiotics, even the newest ones, are becoming less and less effective. One of the ways taken in the Global Plan of Action announced at the World Health Assembly in May 2015 is to ensure the prevention and treatment of infectious diseases. In order to do so, attempts are made to develop new antimicrobial therapeutics, including biomaterials with antibacterial activity, such as polycationic polymers, polypeptides, and polymeric systems, to provide non-antibiotic therapeutic agents, such as selected biologically active nanoparticles and chemical compounds. Another key issue is preventing food from contamination by developing antibacterial packaging materials, particularly based on degradable polymers and biocomposites. This review, in a cross-sectional way, describes the most significant research activities conducted in recent years in the field of the development of polymeric materials and polymer composites with antibacterial properties. We particularly focus on natural polymers, i.e., polysaccharides and polypeptides, which present a mechanism for combating many highly pathogenic microorganisms. We also attempt to use this knowledge to obtain synthetic polymers with similar antibacterial activity.

“…Among different polymers for hydrogel formation, biopolymer carrageenan (CRG) is inexpensive, nontoxic, and biodegradable. [34,35] The carrageenan hydrogels demonstrate excellent film-forming ability and is successfully used for fabrication of composite materials with wide application ranges. [36,37] The sulfate groups of carrageenan are not likely to interact with the Ln 3+ centers in MOF and interfere with the luminescent properties, in contrast to other polycarbohydrate (e.g., alginate) or peptide (e.g., gelatin) biopolymers, which contain carboxylic groups.…”

Highly selective and sensitive quantitative detection of ofloxacin (OFX) at ultra‐low concentrations in aqueous media and development of new afterglow materials remains a challenge. Herein, a new 2D water‐stable lanthanide metal‐organic framework (NIIC‐2‐Tb) is proposed, which exhibits high selectivity towards OFX through the luminescence quenching with the lowest detection limit (1.1 nM) reported to date and a fast response within 6 s. In addition, the luminescence detection of OFX by NIIC‐2‐Tb was not affected by typical components of blood plasma and urine. The excellent sensing effect of NIIC‐2‐Tb was further utilized to prepare a composite functional sensing carrageenan hydrogel material for the rapid detection of OFX in meat in real time and the first discovery of impressive afterglow in MOF‐based hydrogels. This study not only presents novel Ln‐MOF materials and Ln‐MOF‐based hydrogel films for luminescent sensing of OFX, but also demonstrates color‐tunable luminescent films with afterglow, which expands the application of composite luminescent materials for detection and anti‐counterfeiting.This article is protected by copyright.

“…It can be extracted from red seaweeds and has three main types based on its sulfate group: iota-carrageenan, kappa-carrageenan and lambda-carrageenan. 22 One of the key advantages of CG as a catalyst is its ability to form stable complexes with metal ions, which can enhance the efficiency of catalytic reactions. Additionally, carrageenan is biodegradable and non-toxic, making it an environmentally friendly alternative to traditional catalysts.…”
