AFM + Thermal Analysis

Nanoscale Thermal Analysis (nano-TA)

Based on our proprietary thermal probe technology, the afm+ allows you to obtain transition temperatures on any local feature of your sample or to obtain a transition temperature map.

The topography of the sample shows variations in structure, which can then be analyzed using nano-TA. Toner particles include a number of components (wax, resin, dye, etc.) that exhibit different transition temperatures.

Scanning Thermal Microscopy (SThM)

This mode of the afm+ allows you to map relative thermal conductivity and relative temperature differences across your sample.

The 4µm x 8µm image shown here utilizes the scanning thermal microscopy (SThM) functionality of the afm+ system on a carbon fiber – epoxy composite sample. The sample was cut and polished to form a smooth surface. The height image (left) shows a number of carbon fibers, while the SThM image (right) shows the change in probe temperature on the two materials due to their differences in thermal conductivity. This sample demonstrates the high lateral-resolution capability of the SThM technique.

Transition Temperature Microscopy

Transition temperature microscopy (TTM) is a fully automated mode in which an array of nano-TA measurements are rapidly performed and each temperature ramp is automatically analyzed to determine the transition temperature.

The blue areas in the TTM map are amorphous PLLA; the red and yellow areas are crystalline areas. The “onion-like” structure in the spherulite was created by stepping the temperature back and forth during the crystallization process to create regions with a higher or lower degree of crystallinity.

Upgradeable Analytical Capabilities

AFM + IR Spectroscopy

• Point-and-click nanoscale IR spectroscopy

• IR spectra that correlate to FTIR libraries

• Chemical imaging


Topography and IR images collected at 1650 cm-1 and 1740 cm-1 of Streptomyces bacteria. These bacteria form lipid-filled vesicles in later stages of growth. The location of these vesicles can be determined by imaging at 1740 cm-1, an absorption band specific to the lipid. The vesicles can be resolved to sub-100nm resolution using the nanoIR.

AFM + Mechanical

Mechanical properties of your sample can be collected using a contact resonance method to map stiffness variations simultaneously with the topography.

Multifunctional Nanoscale Measurement Suite

The new afm+ is fully upgradeable to our nanoIR system, a probe-based measurement tool that utilizes infrared spectroscopy to reveal chemical composition at the nanoscale. The nanoIR also provides high-resolution characterization of local topographic, mechanical, and thermal properties. Potential application areas span the realms of polymer science, materials science, and life science, including detailed studies of structure-property correlations.

The two materials can be clearly identified by their unique absorption bands. In addition, the difference in stiffness and transition temperature of the two materials can be measured.
