(A) LA-ICP-MS signal in line scan mode recorded for laser beam pass across one printed line at laser spot diameter of 100 μm, scan speed of 20 μm s⁻¹, laser beam fluence of 8 J cm⁻² and repetition rate of 10 Hz. (B) Duration of scanning of the sample area of 15 × 15 mm at various scan speeds (μm s⁻¹). (C) Relative broadening of a printed line (expressed in %) with width of 800 μm obtained at various scan speeds (μm s⁻¹). (D) Elemental maps of C, Si and Zn obtained at “soft” ablation parameters (2 J/cm⁻²) for tissue K320/1 (12 weeks old). (E) Elemental maps of C, Si and Zn obtained at “hard” ablation parameters (8 J/cm⁻²) for tissue K320/1 (12 weeks old).
