  • Publication number: 20230175965
    Abstract: Microscopic analysis of a sample includes a fluorescent dye disposed within the sample. A mid-IR optical source generates a mid-infrared beam, which is directed onto the sample to induce a temperature change by absorption of the mid-infrared beam. An optical source generates a probe beam directed to impinge on the sample. A detector detects fluorescent emissions from the sample when the probe beam impinges on the sample. A data acquisition and processing system acquires and processes the detected fluorescent emissions from the sample to: (i) generate a signal indicative of infrared absorption by the sample, (ii) generate a signal indicative of temperature in the sample based on the signal indicative of infrared absorption by the sample, (iii) generate an image of the sample using the signal indicative of temperature in the sample.

  • Publication number: 20220349818
    Abstract: Systems and methods for sensing vibrational absorption induced photothermal effect via a visible light source. A Mid-infrared photothermal probe (MI-PTP, or MIP) approach achieves 10 mM detection sensitivity and sub-micron lateral spatial resolution. Such performance exceeds the diffraction limit of infrared microscopy and allows label-free three-dimensional chemical imaging of live cells and organisms. Distributions of endogenous lipid and exogenous drug inside single cells can be visualized. MIP imaging technology may enable applications from monitoring metabolic activities to high-resolution mapping of drug molecules in living systems, which are beyond the reach of current infrared microscopy.
