Adhesion-enhanced coral cells with self-healing coating

Preparing stable coatings on alloy substrate has generated considerable interest because of their wide applications in biosensors, electronics and mechanical components. Here we report a promising strategy for fabricating the coatings on alloy substrates based on layer-by-layer self-assembly (LBL) technique. The strategy provides a convenient approach to achieve coating on alloy substrate by employing hydrogen peroxide (H2O2), chitosan (CS), and dialdehyde starch (DAS). Scanning electron microscope (SEM), atomic force microscope (AFM), metallographic microscope were used to characterize the coated substrates. The resulting coating has good cellular compatibility and is used to promote coral cell adhesion. Hence, the developed strategy exhibited a promising application with intensive high adhesive properties for iron contained alloy substrates.
