Optical Photothermal IR: O-PTIR non-contact submicron infrared spectroscopy, used by the mIRage microscope, uses a visible light probe to detect photothermal expansion.

The result of over a decade of development in photothermal physics. IR Spectroscopy is a widely used technique with a strong limitation regarding spatial resolution.

Based on the Photothermal Infrared Technology (PTIR), Photothermal Spectroscopy Corp. has developed the mIRage. The mIRage is an IR microscope to overcome the limitation of classical IR technology.

The reason might be attributed to the fact that the near-infrared light difficultly penetrated through the large-size PBNPs. These results revealed that PBNP-CaCO 3-based immunoassay had high photothermal effect for the determination of target CA Optimization Cited by: 1.

Introduction. Plasmonic metamaterial sensors have been a subject of increasing interest in recent years because they offer the capability to precisely engineer the interaction between electromagnetic radiation and analytes to perform highly sensitive measurements of absorption or refractive index changes [1–3].Metamaterial sensors have shown a high degree of promise for Cited by:   Vibrational mid-infrared photothermal spectroscopy using a fiber laser probe: asymptotic limit in signal-to-baseline contrast.

Optimization of mid-IR photothermal imaging for tissue by: FTIR stands for Fourier transform infrared, the preferred method of infrared spectroscopy. When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted).

The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.
