In their research article “High-resolution imaging of graphene by tip-enhanced coherent anti-Stokes Raman scattering” Xiaolong Kou, Qian Zhou, Dong Wang, Jinghe Yuan, Xiaohong Fang and Lijun Wan report how they achieved the first single atom layer TECARS (tip-enhanced coherent anti-Stokes Raman scattering ) imaging on Graphene with the highest resolution about 20nm.*
The authors used a NANOSENSORS AdvancedTEC™ ATEC-NC AFM tip that they coated with a 20nm Au coating by E-beam evaporation.
With some technological improvements TECARS imaging could be a promising tool for the study of the biochemistry of materials and live cells at the molecular and subcellular levels without labelling as well as other biological, chemical and medical applications.*
