From: Substrate-Mediated Laser Ablation under Ambient Conditions for Spatially-Resolved Tissue Proteomics

Evolution of the signal profiles (for most significant signals) from (A) glass substrate and (B) stainless steel substrate on a rat brain tissue section (60 μm thickness) for 1.0, 1.5, 2.0 and 2.4 mJ/pulse ablation laser energy.
Inserts show a microscopic observation of the irradiated tissue area from glass substrate (left) and stainless steel substrate (right). Each bar represents the sum of the signal intensity over the 9 experiments.
