3D-printed and In-situ prepared hydrogel anti-bacterial wound patch with silver nanoparticle embedded matrix.

The application of wearable hydrogel wound patches has great potential in advancing the field of medicine. However, for high reach and large-scale utilization, the fabrication process of wearable hydrogel wound patches needs to be low-cost, reliable, and have high throughput. Therefore, the incorporation of 3D-printing technology helps in providing a starting point for flexible, high throughput, mechanically enhanced, low-cost, and reliable antibacterial wound patches. 3D-printed patches can perform antibacterial behavior while exhibiting a fast fabrication process in a time range of less than 3 h. The fabricated patch exhibited good water retention, water vapor transmission rates a porosity values indicating that it has a promising potential to be commercialized as a wound patch.
