Abstract

Abstract : We observed an unprecedentedly narrow amide I vibrational band from a bacterial biofilm protein at the air/water interface. Abstract : We characterized BslA, a bacterial biofilm protein, at the air/water interface using vibrational sum frequency generation spectroscopy and observed one of the sharpest amide I bands ever reported. Combining methods of surface pressure measurements, thin film X-ray reflectivity, and atomic force microscopy, we showed extremely ordered BslA at the interface.
