Atomic Force Microscope
MFP-3D-BIOTM Atomic Force Microscope by Asylum Research is mounted on Olympus IX71 inverted microscope that resides on a Herzan AVI 350-S Active Vibration Isolation Table which dynamically dampens the most extreme vibrational disturbances; and the system is totally enclosed in an air tight state-of-the-art BCH-45 Large Acoustic Isolation Hood with air temperature control capabilities. The closed looped system allows investigation of dry or hydrated biological/materials surface features at very high resolution to include dynamic 3D visual analysis, force curves, optical (fluorescence and phase) image overlays precisely registered over AFM topographical information; plus advanced modes such as nanomanipulation(s), nanoindentation(s), Dual AC and more. The system software modules are written in Igor Pro, an integrated program by Wavemetrics which provides very advanced features for visualizing, analyzing, transforming and presenting experimental data.
