In this study, a layer-by-layer deposition of poly(L-lysine) and hyaluronic acid (HA) as polyelectrolyte multilayer (PEM) film on polyacrylic (PAA) /HA/ lignin (LIG) disc shaped scaffolds is presented to increase the biological activity for tissue engineering applications. These are electrically conductive via introduction poly(3,4-ethylene dioxythiophene):hyaluronic (PEDOT:HA) nanoparticles (NPs), with diameter 10 mm thickness 3-4 mm. The formation was confirmed through contact angle measurements, fluorescence microscopy scanning electron (SEM) imaging. It found that PEM layers had unexpected benefit increased compression strength decreased swelling tend reinforce struts whilst possibly interfering diffusion pathways. Importantly, results show statistically significant improved attachment proliferation L929 fibroblast cells surface scaffolds. Furthermore, effect varied PEDOT:HA NP addition assessed it concluded samples containing 1% (w/v) exhibited desirable balance between good mechanical characteristics, high conductivity, cell adhesion proliferation. novel composite offer future potential in biomedical applications such engineering, wound healing biosensors.
