Novel ZnO/polyacrylate composites with antibacterial activity against C. ammoniagenes to prevent skin infections

Much of the older population experiences urinary incontinence disorders and often relies on medical supplies such as diapers or pads. However, frequent use of these supplies can lead to unpleasant odors, skin irritations, and infections caused by a bacterium found in human urine called Corynebacterium ammoniagenes. To address the hygiene and health concerns associated with these supplies, novel composite materials consisting of zinc oxide impregnated on sodium polyacrylate were synthesized through diverse methods. These composites were then tested against the C. ammoniagenes bacterium to assess their viability as components of urinary incontinence supplies. Overall, the synthesized composites exhibited considerable efficacy against the targeted bacterium. Moreover, the sample synthesized with more water used in sodium polyacrylate dispersion demonstrated the highest level of inhibition. Complete bacterial inhibition was achieved within 24 h of contact, with a minimum inhibitory concentration of 1.66 mg/mL. The results indicate that the synthesized composites hold significant potential for addressing the hygiene and health concerns associated with urinary incontinence supplies, presenting a promising avenue for improving the quality of life of individuals affected by this condition.
