In vitro investigation of protein assembly by combined microscopy and infrared spectroscopy at the nanometer scale atomic force microscopy
What is atomic force microscopy?
Various imaging methods, including transmission electron microscopy and atomic force microscopy (AFM) in liquid settings, have been extensively used to study the nanoscale structure and dynamics of proteins on surfaces. However, because to the potential for destruction or perturbation of fragile biological material and the lack of chemical information provided by these potent imaging techniques, a fundamental understanding of the dynamic processes driving their genesis under physiological settings is not possible.
Here, we employ a platform created in our lab that allows for the nanometer-resolution capture of infrared (IR) spectroscopy and AFM pictures of biological material in physiological liquids in a cell surrounded by atomically thin graphene membranes permeable to IR photons. In this research, we looked at how S-layer proteins self-assemble at the graphene-aqueous solution interface.
