10nm chemical imaging spatial resolution with Tapping AFM-IR

"The nanoIR2 is a go-to tool for unique nanoscale IR analysis, and has solved many problems to the delight of our academic and industrial users."

The University of Delaware purchased the nanoIR2 in a multiuser facility which I manage. Once the instrument was available to my users, it became a go to tool for unique IR analysis. The nanoIR2 has proved to be a very robust platform with great stand-alone AFM capabilities. The user interface is clear and very intuitive, and the software never crashes. Many problems in manufacturing and failure analysis have been solved or identified to the delight of my industrial users. I look forward to many more years of satisfying use of the Anasys nanoIR2".

Tapping AFM-IR images show lenticular crystals; overall thickness (50 nm) indicates multilayer crystals. Characteristic IR absorption band of PHBHx. The band shape between 1700-1760 cm-1 reveals fairly similar crystallinity at different sites. An absorption band at 1510 cm-1 is also observed, indicating presence of aromatic moiety, not observed for 3.9 mol% sample.

AFM-IR Applications


Wide range of AFM-IR applications with spatial resolution down to 25nm and <10nm sensitivity

Chemical analysis of semiconductor devices

nanoIR measurements on layers in a semiconductor device. The analysis reveals variations in chemical composition not measurable by conventional IR microscopy.

Interface analysis of composites

nanoIR measurements on a carbon fiber-epoxy composite revealing variations in chemical composition across the fiber/epoxy interface. This measurement was performed on a polished bulk sample.

Organic nanocontaminant on metal surface

Spectra collected using the resonant enhanced mode allows identification of nanoscale organic contamination on a magnetic disk. This particle has dimensions of approximately 100 nm x 200 nm x 28 nm.

Microtomed toner particle

Toner particles are a complex mixture of multiple components, the nanoIR allows identification and localization of these components with nanoscale resolution.

hydrocarbons on minerals
