Figure 6

Superhydrophilicity of the (a–e) platinum, (f, g) silicon, and (h, i) glass surfaces after femtosecond laser treatment. (a–d) Laser-induced multiple parallel microgrooves on the platinum surface. (e) Methanol quickly wetting the structured metal surface. (f) Laser-induced microstructure on the silicon surface. (g) Water wetting and spreading uphill on the structured silicon surface. (h) Laser-induced microstructure on the glass surface. (i) Water wetting and spreading uphill on the structured glass surface. Reproduced from [9698] with the permission.
