Aspects of the present invention include systems and devices useful for surface chemical analysis of solid samples by Tip Enhanced Raman Spectrometry ("TERS"), and particularly it relates to devices useful for chemical analysis of molecular compounds located either on or within thin surface layer of solid samples. Even more particularly, aspects of the present invention relate to systems, and devices for non-destructive analysis combining both high sensitivity and high spatial resolution of analysis of chemical compounds located or distributed on the surface of solid samples with obtaining important information regarding vibration spectra of atoms and molecular groups contained in a thin surface layer of solid samples. These objectives are realized by implementation of computer-assisted systems that use sensors to carefully regulate the motion of, and force applied to, probes of atomic force microscopes.
