Bio-AFM instruments in the Surface Science Facility at the ASRC

Our novel Bio-AFM setup employs Bruker JPK atomic force and Andor Dragonfly confocal fluorescence systems in tandem to produce powerful analyses of biological samples. The Bruker JPK system comes with three different AFM heads and several different scan modes. Experiments can be designed with focuses on speed, resolution, and sample dynamics. The Andor Dragonfly system includes several imaging methods, including a spinning disk confocal which decreases time required for data collection. Images taken with the Dragonfly can be overlaid onto the JPK scan area to collect AFM data on specific cells of interest.
