我们的特点BslA，细菌生物膜蛋白，在空气/水界面振动和频率发生光谱，并观察到一个最尖锐的酰胺我带有史以来报道。结合表面压力测量，薄膜X射线反射率，和原子力显微镜的方法，我们在界面处显示出非常有序的BslA。
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 band 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.
