Hybrid Biopolymer Coating on Stainless-steel Substrate for Surface Lubrication

This research evaluated the use of naturally-derived biomaterials (i.e. chitosan-polydopamine) to lubricate the hypodermic needles. The coating was found to reduce the drag force of the needles when penetrating through an artificial skin in both dry and wet conditions. In addition, the lubricity of the coating was retained after multiple reuse. Future work is required to improve the lubricity of the coating.
