Label-free autofluorescence-detected photothermal mid-IR (AF-PTIR) microscopy is applied to test the distribution of materials within a sample. Two-photon excited UV-fluorescence (TPE-UVF) supports autofluorescence of native aromatic moieties using visible-light optics. Thermal modulation of the fluorescence quantum yield serves to report on infrared absorption, enabling infrared spectroscopy in the fingerprint region with a spatial resolution dictated by fluorescence. AF-PTIR provides high selectivity and sensitivity in image contrast for aromatic fluorescent materials, complementing broadly applicable optical photothermal IR (O-PTIR) microscopy based on photothermal modulation of refractive index / scattering. Mapping the fluorescent material distribution can be used to improve processes such as powdered dosage form manufacturing, with high spatial variance potentially producing variability in both delivered dosage and product efficacy. The ubiquity of aromatic moieties within active pharmaceutical ingredient candidates in particular suggests the viability of AF-PTIR in combination with O-PTIR to improve the confidence of chemical classification in spatially heterogeneous dosage forms.
