Anasys
Instruments, the company that pioneered nanoscale thermal analysis and
nanoscale IR spectroscopy using an AFM, has chosen the Fall 2011 MRS meeting to
introduce a brand new, easy-to-use research and analysis tool. The afm+ is the
first fully integrated AFM platform to offer three important analytical
capabilities.
Using Anasys' proprietary thermal probe technology for Nanoscale Thermal
Analysis (nano-TA), the afm+ allows the user to obtain transition temperatures
on any local feature of a sample or to obtain a transition temperature map. It
makes measurement of glass transition temperatures (Tg) and melting
temperatures (Tm) a simple operation. This mode also includes Scanning Thermal
Microscopy (SThM) which allows the user to map relative thermal conductivity
and relative temperature differences across the sample.
Transition temperature microscopy (TTM
TM) is used to quantify and map thermal
transitions in heterogeneous materials. Transition temperature microscopy (TTM)
is a fully automated mode in which an array of nano-TA measurements is rapidly
performed and each temperature ramp is automatically analyzed to determine the
transition temperature.
Finally, the afm+ is fully upgradeable to perform nanoscale infrared
spectroscopy for measuring and mapping chemical composition on the nanoscale.
This technology enables point-and-click nanoscale IR spectroscopy that produces
IR spectra that correlate to FTIR libraries. This makes chemical imaging on the
nanoscale a reality. The upgrade options also include the ability to measure
the mechanical properties of samples. Data may be collected using a contact
resonance method to map stiffness variations simultaneously with the topography.
In summary, the afm+ is providing the basis for a multifunctional nanoscale
measurement suite. The afm+ is fully upgradeable to the Anasys 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.
