Synthesis and characterisation of a novel poly(2‐hydroxyethylmethacrylate)‐chitosan hydrogels loaded cerium oxide nanocomposites dressing on cutaneous wound healing on nursing care of chronic wound

AbstractThis study was designed to establish the composition of wound dressing based on poly(2‐hydroxyethylmethacrylate)‐chitosan (PHEM‐CS) hydrogels‐loaded cerium oxide nanoparticle (CeONPs) composites for cutaneous wound healing on nursing care of the chronic wound. The as‐synthesised PHEM‐CS/CeONPs hydrogels nanocomposites were characterised by using UV–visible spectroscopy, scanning electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, and thermo gravimetric analysis. The influence of PHEM‐CS/CeONPs hydrogels nanocomposites on the gelation time, swelling ratio, in vitro degradation, and mechanical properties was investigated. The as‐prepared PHEM‐CS/CeONPs hydrogels nanocomposites dressing shows high antimicrobial activity against Staphylococcus aureus and Escherichia coli. Similar trends were observed for the treatment of biofilms where PHEM‐CS/CeONPs hydrogels nanocomposites displayed better efficiency. Furthermore, the biological properties of PHEM‐CS/CeONPs hydrogels nanocomposites had non‐toxic in cell viability and excellent cell adhesion behaviour. After 2 weeks, the wounds treated with the PHEM‐CS/CeONPs hydrogels nanocomposite wound dressing achieved a significant closure to 98.5 ± 4.95% compared with the PHEM‐CS hydrogels with nearly 71 ± 3.55% of wound closure. Hence, this study strongly supports the possibility of using this novel PHEM‐CS/CeONPs hydrogels nanocomposites wound dressing for efficient cutaneous wound healing on chronic wound infection and nursing care.
