What kind of information can be obtained with these instruments?
The following information can be obtained with our SPM instruments:
Surface morphology. Topography with resolution below 1 nm.
Electrical conductivity (c‐AFM). Quantitative local electrical resistance measurements.
Mechanical properties (QNM Peakforce). Quantitative local measurement of the elastic modulus, adhesion, stiffness, energy dissipation and deformation on surfaces.
Local electrical potential (KPM). Qualitative measurements of local charge distribution.
Magnetic properties (MFM). Magnetic properties analysis under magnetic fields.
Nanomechanical studies by using Single Molecule Force Spectroscopy. Pull‐push experiments for inter and intra-molecular force measurements, with 1 pN resolution.
Electro-chemical properties (EC‐SPM). Study of chemical reactions on surfaces under controlled environments.
Piezo-electric properties (PFM). Using the tip as electrode and deformation sensor.
Thermal dependence. Capacity to measure in the 250 K to 500 K range.
Topography based in ambient Scanning Tunnel Microscopy (STM).
The sample should be immobilized onto a flat substrate (for instance, biomolecules should be immobilized onto a mica surface via adsorption or via a covalent procedure).
The sample should exhibit a lower roughness than the range of the piezo scanner.
The size of the sample should be small enough to fit inside of the microscope, around 1 cm2 in surface and 0.5 cm in thickness.
Types of samples that can be studied with the environmental SPMs include:
Biological samples (DNA, proteins and peptides; cells, viruses and bacteria; biological tissues, etc.).
Organic and inorganic thin films.
Gels and Polymers.
