"Three-dimensional micropatterned collagen scaffolds were fabricated by femtosecond laser ablation. An 800 nm, 45 fs Ti:Sapphire laser was used to create various 3D patterns in a collagen gel, including holes, lines and grids.
"An optimal collagen concentration was found for both substrate patterning and cell compatibility," scientists in the United States report.
"The threshold fluence for ablation of the scaffold was found to be 0.06 J/cm2, and the morphology of the ablation craters was measured as a function of fluence,"...
