Bruker Nano SurfacesRequest Info
Bruker Corp.'s Nano Surfaces Div. has released the Innova-IRIS, an integrated system for correlated atomic force microscopy (AFM) and Raman spectroscopic imaging. Its ultralow closed-loop noise, no-drift mechanical stability and wide-open optical access make it a suitable platform for tip-enhanced Raman spectroscopy (TERS) research. With hardware integration designed to accelerate a TERS setup, and an IRIS software module that offers automated mapping, the system transforms AFM and Raman instruments into TERS-enabled research platforms. It provides a solution for routinely correlating AFM nanoscale property maps with Raman chemical images to address nanoscale materials analysis applications. It leverages the performance and AFM head design of the Innova platform to provide TERS-ready AFM-Raman integration suitable for sensitive interrogation of opaque samples.

tip-enhanced Raman spectroscopy
A spectroscopic technique that combines the high chemical specificity of Raman scattering and signal sensitivity provided by surface plasmon resonance enhancement, with the nanoscale spatial resolution of scanning probe microscopy (SPM). Supported by a sharp metallized-SPM tip, tip-enhanced Raman spectroscopy (TERS) enables label-free detection of surface components in multicomponent samples with ultrahigh spatial resolution, making it suitable for studying nanomaterials.
