Structural and mechanical mapping at the nanoscale by novel high-speed multiparametric
Quantitative Imaging (QI) and PeakForce Quantitative Nanomechanical Mapping (PF-QNM)
AFM modes was compared to the classical Force Volume (FV) mapping for the case of living
Pseudomonas aeruginosa bacterial cells. QI and PF-QNM modes give results consistent
with FV for the whole cells in terms of morphology and elastic modulus, while providing
higher resolution and shorter acquisition time. As an important complement, the influence of …
