Toward Nanoscale Structural and Chemical Analysis of Microbial Surfaces.

Microbial surfaces play a critical role in various biological processes including cell adhesion and biofilm formation. Understanding these surfaces at the nanoscale is essential for both fundamental and applied microbiology. This review explores recent advancements in nanoscale structural and chemical analyses of microbial surfaces, with a focus on vibrational spectroscopy, such as Raman spectroscopy, infrared spectroscopy, and atomic force microscopy. The review also discusses current challenges of these techniques, including variability in sample preparation and the reproducibility of data, and highlights future directions in nanoscale analysis that could lead to new insights in microbial physiology, antimicrobial resistance, and biofilm research.
