| Abstract | Fouling of surfaces due to bioadhesion is one of the hurdles in terms of their practical applications. Inspired by mussel and lotus leaf, antibioadhesive superhydrophobic syringe needles are fabricated by sequential bonding of polydopamine, Ag nanoparticles, and 1H,1H,2H,2H-perfluorodecanethiol (PFDT). The morphology and surface chemical composition of the needles are characterized. The wetting properties and antibioadhesive properties of the needles are evaluated by contact angle (CA) and sliding angle (SA) of water and various aqueous solutions, and their residues on the needles after repeatedly used for liquid handling. The superhydrophobic needles show a rough surface with a layer of PFDT, which endow them with very high CA and low SA for water and various aqueous solutions. In addition, the aqueous solutions are in the Cassie-Baxter state on the surface of the superhydrophobic needles. Thus, the adhesion force between the superhydrophobic needles and aqueous solutions is very low. This endues the needles with excellent antibioadhesive properties and can be repeatedly used for withdrawing and dispensing various aqueous solutions. Moreover, the superhydrophobic needles can be used for the transport of aqueous solutions at high accuracy. The antibioadhesive superhydrophobic needles may find applications in various fields such as liquids transport and inkjet printing devices. |
