title: Rapid ambient mass spectrometric profiling of intact, untreated bacteria using desorption electrospray ionization.
abstract: Desorption electrospray ionization (DESI) allows the rapid acquisition of highly reproducible mass spectra from intact microorganisms under ambient conditions; application of principal component analysis to the data allows sub-species differentiation.
