AFM technique uses the tip as a sensor and relies on a scanning technique to produce, in a non destructive way, very high resolution 3-D images of sample surfaces. Furthermore, by appropriate choice of the acquisition scheme, it is able to discriminate among materials of different nature disposed on the same surface. AFM technique plays a key role in any context in which nanometer size objects have to be characterized. For this reason in our laboratories it is of fundamental importance for the morphological characterization of protein aggregates. Indeed, it permits very easily evaluation of the protein aggregate’ shape distinguishing among globular and fibrillar aggregates, the details of its surface morphology, their degree of aggregation and/or agglomeration, etc. Moreover, AFM measurements, characterize the morphology of the supramolecular assemblies during the aggregation pathway.

 


Atomic Force Microscope

Model: Veeco MultiMode V Scanning Probe Microscope.
Measurement temperature and environments
: from 250K to 525K in air, controlled atmosphere or liquid.
Modes of operation: STM, AFM (contact, non-contact, tapping, torsional, tunneling, etc)

Scanners:
Open-loop: Types E (maximum range=12μm, high resolution) and J (maximum range=120μm, low resolution). Closed-loop: Type J-nPoint (maximum range=100μm).
