Polysaccharides are a class of natural biopolymers that have attracted significant attention due to their unique properties, which make them attractive for use in a wide range of applications. These biopolymers have an important role in our daily life, and designing biomaterials for biomedical applications requires careful consideration of factors such as biocompatibility, biodegradability, renewability, affordability, and availability, all of which can be achieved with polysaccharides. This review paper focuses on the use of polysaccharides in biomedical applications and provides an in‐depth analysis of the potential applications of arabinoxylan, a type of hemicellulose, in various fields, including drug delivery, infection control, tissue engineering, wound healing, and others. Arabinoxylan, which is derived from plants, is the most abundant and important class of hemicellulose and has a diverse role as a catalyst due to its biodegradability, biocompatibility, and renewable nature. Polysaccharide‐based biopolymers have applications in tissue engineering, wound covers, drug delivery systems, food preservation, and biocomposite films, making them an emerging excipient in pharmaceutical research. This review paper highlights the potential of polysaccharide‐based biopolymers in biomedical science and suggests that continued research and development will lead to broader and more innovative applications in the field. The use of polysaccharide‐based biopolymers has the potential to significantly advance healthcare and improve patient outcomes.

Emphasizing mixed polymer brush synthesis techniques, morphologies, and their impact on protein interactions. These brushes are crucial in drug delivery, wound repair scaffolds, and biomedical fields by altering protein interactions.

Increasing contamination of water bodies with antibiotics has necessitated the development of novel mitigation methods. Many studies have applied adsorption and photocatalytic processes using different nanoparticles, metal‐organic frameworks, etc., as sorbents and photocatalysts for antibiotics removal. Among these materials, the development of molecular imprinted polymers (MIPs) is desirable owing to their low cost, structural predictability, detection at deficient concentrations, and versatile applicability. These attributes further encouraged researchers to fabricate hybrid MIP‐based materials to abate antibiotic contamination in wastewater. This review summarizes recent studies that deal with conventional and hybrid MIPs such as MIPs‐hybrid carbon nanomaterials, magnetic nanomaterials, advanced MIP‐based sensors, and photocatalytic materials MIPs for synergic adsorption/separation of antibiotic residuals from wastewater. Economic perspectives of the emerging hybrid materials are also discussed. Some limitations, research gaps, and future potentials for further advancement and efficient remediation results are outlined.

In this work, binary mixed polymer brushes based on poly[(2-methyl-2-oxazoline)-random-glycidyl methacrylate] (PMOXA-r-GMA) and poly(glycidyl methacrylate)-block-poly(N-isopropyl acrylamide)-block-polystyrene (PGMA-b-PNIPAM-b-PSt) were used as thermoresponsive coating to control protein adsorption. Firstly, PMOXA-r-GMA was synthesized via cationic ring opening polymerization of 2-methyl-2-oxazoline followed by its copolymerization with glycidyl methacrylate (GMA); PGMA-b-PNIPAM-b-PSt was synthesized by reversible addition–fragmentation chain transfer polymerization of GMA, N-isopropyl acrylamide, and styrene sequentially. Then the mixed brushes were fabricated successfully by spin coating the mixture of PMOXA-r-GMA and PGMA-b-PNIPAM-b-PSt solutions onto silicon or glass substrates followed by an annealing protocol using GMA segments as an anchor. Afterwards, the investigation for adjusting the hydrophobic property of mixed brushes was performed. The results showed that when the environmental temperature is lower than the lower critical solution temperature (LCST) of PNIPAM, the tethered PNIPAM blocks are swollen and could bring the hydrophobic PSt block with optimum molar mass to the surface; when the environmental temperature is higher than the LCST of PNIPAM, the PNIPAM blocks collapse and could bring the hydrophobic block inside the hydrophilic PMOXA grafted polymer layer. Finally, the protein adsorption on mixed polymer brushes was investigated using a fluorescein isothiocyanate-labelled protein assay and ellipsometrys. The results showed that under the optimum molar mass of PSt block, mixed brushes could adsorb proteins in large quantities below the LCST of PNIPAM, and display resistance to protein adsorption above the LCST of PNIPAM.
