Executive Industry Relevance

Contact mode atomic force microscopy (AFM) enables rapid, high-resolution morphological assessment of bacterial cells, supporting early-stage evaluation of antimicrobial interventions. This technique provides actionable 3D topography and cell damage data without the complexity or cost of electron microscopy, facilitating efficient screening of nanoparticle effects on bacterial integrity. AFM's operational simplicity and quantitative outputs position it as a valuable tool for mechanistic de-risking and target validation in anti-infective discovery pipelines.
