Development and evaluation of silver-infused Biopolymer coated cotton wound dressings as possible wound healing material

Wound management is a critical clinical issue, with substantial economic and social implications. Traditional dressings often lead to poor healing, impacting the effective wound repair is an ongoing challenge. So, this research aimed to investigate the development of a novel medical textile auxiliary in the form of a padded cotton bandage coated with a blend of agricultural biopolymers (xanthan gum and gum arabic) containing AgNPs with an emphasis on environmental friendliness and sustainability. The samples treated with various biopolymer blend compositions that were assessed by SEM and FTIR analysis, tensile strength, antibacterial properties, and comfort attributes, including air permeability and wicking. Antibacterial tests showed no bacterial growth on the samples, with the maximum inhibition zone measuring 3.3 mm. The mechanical and comfort tests revealed that the blend with 0.5 % xanthan gum and 1 % Arabic gum achieved the highest air permeability at 500 mm/s, the sample with the highest GSM demonstrated superior tensile strength at 42 N, and the 50 GSM sample exhibited better-wicking properties, reaching up to 1.33 cm, compared to the 100 GSM samples. This research is aimed to develop biopolymer-based cotton bandages with improved air permeability, antibacterial, tensile strength, moisture-wicking.
