Abstract
An implant includes a microstructured hyperhydrophilic surface with protrusions and depressions in which a spacing between the protrusions as a statistical mean is in a range of 1 to 100 μm and a profile height of the protrusions and depressions as a statistical mean is in the range of 1 to 80 μm.
Claims11
An implant comprising:
- an implant having a first microstructured hyperhydrophilic surface with protrusions and depressions, wherein the spacing between the protrusions as a statistical mean is in a range of 1 to 100 μm and a profile height of the protrusions and depressions as a statistical mean is in a range of 1 to 80 μm,
- wherein the implant has a microscopic roughness factor (rM) in a range between 2 and 50, and
- wherein at least one of two dynamic contact angles θV and θR of the hyperhydrophilic surface is in a hyperhydrophilic range with 1.0<ΔF/(P·γ)≤2.15,
- wherein θV stands for advancing angle, θR stands for receding angle, ΔF stands for a difference between measured net forces, γ stands for surface tension of water, and P stands for perimeter of the sample.
