DESCRIPTION:Dr. Bogdan Sava\, Attocube Systems GmbH\, Germany\nAtomic forc
 e microscopy (AFM) has long been established as a versatile tool for imagi
 ng and probing materials at the nanoscale. Over the years\, numerous AFM m
 odes such as PFM\, KPFM\, and cAFM have extended its capabilities from pur
 ely topographic imaging. Building on these advances\, AFM-IR emerged as a 
 powerful technique to access local vibrational information\, linking mecha
 nical interaction with chemical specificity. The addition of confocal Rama
 n microscopy further expanded the spectroscopic dimension\, while maintain
 ing AFM as the structural backbone of the analysis.\n\nIn this talk\, we w
 ill present the next evolutionary step in this trajectory: a correlative a
 pproach that unifies AFM\, AFM-IR\, Raman micro-spectroscopy\, nano-IR\, a
 nd µ-IR analysis. This seamless integration enables researchers to invest
 igate samples across length scales ranging from micrometers down to sub-10
  nm resolution\, with direct correlative power.\n\nWe will illustrate thes
 e capabilities through several case studies. For instance\, phase separati
 on in thin polymer blend films can be visualized topographically by AFM\, 
 chemically resolved at the nanoscale by AFM-IR and nano-FTIR\, and cross-v
 alidated with Raman signatures. Likewise\, the analysis of micron-sized MO
 F crystallites demonstrates how AFM and AFM-IR reveal nanoscale heterogene
 ity and contaminants\, while Raman and LDIR provide complementary chemical
  mapping on larger scales.\n\nBy presenting this evolutionary path—from 
 AFM to multimodal correlative vibrational spectroscopy—we will show how 
 IRa-SCOPE [1] enables comprehensive micro- to nanoscale characterization\,
  supporting advanced research in polymer systems or functional materials.\
