2025年3月4日 · The near infrared (NIR, > 800 nm) is advantageous for imaging applications because it falls into the tissue transparency window and also contains vibrational overtone and combination modes useful for molecular fingerprinting. Here, fast hyperspectral NIR imaging is demonstrated using a spectral phasor transformation (HyperNIR).

Near-infrared (NIR) light possesses many suitable optophysical properties for medical imaging including low autofluorescence, deep tissue penetration, and minimal light scattering, which together allow for high-resolution imaging of biological tissue.

Near-infrared imaging is a technique that allows non-invasive inspection of the brain with high tempo-spatial resolution using NIR fluorophores, such as nanomaterials, organic molecules, and macro biomolecules, for imaging and clinical applications.

2017年1月10日 · In vivo near-infrared (NIR) fluorescence imaging is an emerging biomedical imaging modality for use in both fundamental scientific research and clinical practice.

2023年6月1日 · Near Infrared (NIR) spectroscopy is a powerful analytical technique that uses the absorption of electromagnetic radiation in the near infrared region of the electromagnetic spectrum to provide valuable insight into the molecular composition of a sample.

2011年10月21日 · Near Infrared Spectroscopy and Imaging (NIRS) uses near infrared light between 650 and 950 nm to non-invasively probe the concentration and oxygenation of hemoglobin in the brain, muscle and other tissues and is used e.g. to detect changes induced by brain activity, injury, or disease.

2024年4月4日 · Fluorescence imaging in the second near-infrared (NIR-II) window enables deep-tissue imaging with high resolution and improved contrast by taking advantage of the reduced light scattering and...

Near-infrared (NIR) fluorescence imaging using biocompatible dyes such as ICG in the NIR-I (800–1,000 nm) has facilitated tumor imaging and imaging-guided surgery, but suffers from shallow imaging depth, low contrast, and poor clarity caused by light scattering and autofluorescence.

In this review, we discuss state-of-the-art NIR optical imaging techniques in cancer immunotherapy to observe the dynamics, efficacy, and responses of the immune components in living organisms. The use of bioimaging labeling techniques will give us an understanding of how the immune system is primed and ultimately developed.

A diagnostic imaging modality based on near-infrared (NIR) radiation offers several potential advantages over existing radiological techniques. First, the radiation is non-ionizing, and therefore reasonable doses can be repeatedly employed without harm to the patient.
