Graphene Oxide Carboxymethylcellulose Nanocomposite for Dressing Materials

Area of Science:

• Biomaterials Science
• Nanotechnology
• Wound Healing

Background:

• Sore, infected wounds present significant clinical challenges, necessitating advanced biomaterials for effective dressings.
• Current treatments require novel multifunctional materials to improve wound management and healing outcomes.

Purpose of the Study:

• To develop and characterize novel biocomposites using carboxymethylcellulose (CMC) and exfoliated graphene oxide (Exf-GO) for wound dressing applications.
• To evaluate the structural, morphological, mechanical, and biological properties of the CMC/Exf-GO biocomposites.

Main Methods:

• Biocomposites were synthesized via solvent casting with varying concentrations of CMC and Exf-GO.
• Exfoliated graphene oxide (Exf-GO) was prepared through graphite oxidation and exfoliation.
• Structural, morphological, and mechanical properties were assessed, alongside antibacterial activity and cytotoxicity.

Main Results:

• Homogeneous, transparent, brownish biocomposites (CMCx/Exf-GO) were successfully prepared, indicating good dispersion of Exf-GO within CMC.
• The biocomposites demonstrated significant inhibitory activity against Gram-positive Staphylococcus aureus.
• No cytotoxic effects were observed on normal fibroblasts, and no significant activity was noted against Gram-negative Pseudomonas aeruginosa.

Conclusions:

• CMC/Exf-GO biocomposites are promising multifunctional materials for wound dressings.
• These materials exhibit selective antibacterial properties against Gram-positive bacteria and are biocompatible with normal human cells.
• Further research into these advanced wound care materials is warranted.
