Far-field chemical microscopy providing molecular electronic or vibrational fingerprint information opens a new window for the study of three-dimensional biological
material
and chemical systems. Chemical microscopy provides a nondestructive way of chemical identification without exterior labels. However
the diffraction limit of optics hindered it from discovering more details under the resolution limit. Recent development of super-resolution techniques gives enlightenment to open this door behind far-field chemical microscopy. Here
we review recent advances that have pushed the boundary of far-field chemical microscopy in terms of spatial resolution. We further highlight applications in biomedical research
material characterization
environmental study
cultural heritage conservation
and integrated chip inspection.
