Abstract
Polymeric drugs containing up to 60% by weight of the antibiotic vancomycin were synthesized based on dextran carriers activated with epichlorohydrin. Vancomycin was covalently bound, involving the primary amino group of the molecule through the hydroxypropyl radical to the C6 position of the anhydroglucose units of the dextran main chain. Covalent binding is necessary to prevent spontaneous release of the antibiotic from the gel, thereby reducing the risk of bacterial multiresistance. Antibacterial depot gels were obtained from those polymers, containing up to 17.5% by weight of polysaccharide with a cross-linking density of q = 3-5 nodes per macromolecule for the deposition of another type of drugs not covalently bound to the polymer gel. They were used to coat the surface of the internal pores of biocomposite bone implants based on bovine cancellous bone used in orthopedics. The chemical structure of the polymer was studied using 13C NMR spectroscopy and matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry. The stiffness of the gels was evaluated by the values of the accumulation modulus G' = 170-270 kPa and the loss modulus G″ = 3.7-4.2 kPa determined on a rheometer. Their values are close to those typical for materials used to replace soft tissue in plastic surgery. The minimum inhibitory concentration of the gels against Staphylococcus aureus P209 depends on the antibiotic content in the polymer. It equals 2.5 mg/L for vancomycin we used and 100 mg/L for a polymer containing 50% by weight of covalently bound antibiotic. The cytotoxic concentration measured with cell culture HEK 293T exceeds 1200 mg/L in 24 h exposure. The release dynamics of drugs not covalently bound to dextran from the depot gel were studied using fluorescein as a model. The release time is independent of the gel density and lasts up to 6 days for a 2 mm thick layer. Both the gel and the bone implants impregnated with it maintained consistently high antibacterial activity throughout the experiment, up to its completion after 168 h, with the local concentration of the released antibiotic at the site of bacterial attack exceeding the therapeutic level by 200 times.

Abstract
A polysaccharide gel containing covalently bound amikacin, a broad-spectrum antibiotic, was produced by using epichlorohydrin-activated hydroxyethyl starch (HES). The structure of the polymers was analyzed by 13C and 1H nuclear magnetic resonance (13C NMR and 1H NMR) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. The sites of covalent attachment of amikacin to the epoxypropyl substituent and the HES backbone were determined. The antibacterial activity of the polymer was evaluated in vitro using the agar well diffusion method with the Staphylococcus aureus P209 strain. It was demonstrated that the polymer retained activity in the presence of bacterial amylase, which is released upon bacterial attack. The gel was applied for coating pores and surfaces of a biocomposite material based on a xenogenic bovine bone matrix. In vivo experiments showed the effectiveness of utilizing amikacin-containing biocomposite bone-substitute materials in the treatment of experimental osteomyelitis in rats using objective histological control and X-ray tomography.

Abstract
Hydrogels, as biological materials, are widely used in food, tissue engineering, and biomedical applications. Nevertheless, many issues remain in the preparation of hydrogels by physical and chemical methods, such as low bioaffinity, weak mechanical properties, and unstable structures, which also limit their applications in other fields. However, the enzymatic cross-linking method has the advantages of high catalytic efficiency, mild reaction conditions, and the presence of nontoxic substances. In this review, we evaluated the chemical, physical, and biological methods of preparing hydrogels and introduced three common cross-linking enzymes and their principles for preparing hydrogels. This review introduced the applications and properties of hydrogels prepared by the enzymatic method and also provided some suggestions regarding the current situation and future development of hydrogels prepared by enzymatic cross-linking.

Abstract
Ibuprofen is a well-known non-steroidal anti-inflammatory (NSAID) medicine that is often used to treat inflammation in general. When given orally, it produces gastrointestinal issues which lead to lower patient compliance. Ibuprofen transdermal administration improves both patient compliance and the efficacy of the drug. Nanoconjugation hydrogels were proposed as a controlled transdermal delivery tool for ibuprofen. Six formulations were prepared using different compositions including chitosan, lipids, gum arabic, and polyvinyl alcohol, through ionic interaction, maturation, and freeze–thaw methods. The formulations were characterised by size, drug conjugation efficiency, differential scanning calorimetry (DSC), and Fourier transform infrared spectroscopy (FTIR). Further analysis of optimised hydrogels was performed, including X-ray diffraction (XRD), rheology, gel fraction and swelling ability, in vitro drug release, and in vitro macrophage prostaglandin E2 (PGE2) production testing. The effects of ibuprofen’s electrostatic interaction with a lipid or polymer on the physicochemical and dissolution characterisation of ibuprofen hydrogels were evaluated. The results showed that the S3 (with lipid conjugation) hydrogel provided higher conjugation efficiency and prolonged drug release compared with the S6 hydrogel.
