Description
Alessandra Signorile and six co-authors make alumina surfaces love water for weeks with laser texturing. Their 2025 paper carves micro-patterns into ceramic plates with femtosecond pulses. Wetting control matters for implants and prostheses that meet body fluids. Most treatments fade within days, though.
Triangular grooves of varied depth were cut into the plates. Water contact angles were tracked daily for over forty days. Deeper grooves held their hydrophilic pull longest. Without a stabilizing bake, the deepest patterns stayed super-wettable the whole test. A bake after cutting changed the balance in the other samples. Groove depth, it turns out, is a dial for lasting wetness.
