Article Abstract
Fluorescent bio-imaging will be the future in the medical diagnostic for visualising inner cellular and tissues. Near-infrared (NIR) emitting fluorescent probes serve dynamically for targeted fluorescent imaging of live cells and tissues. NIR imaging is advantageous because of its merits like deep tissue penetration, minimum damage to the tissue, reduced auto fluorescence from the background, and improved resolution in imaging. The Development of the NIR emitting probe was well explored recently and growing drastically. In this review, we summarise recent achievements in NIR probes in between 2018-2021. The merits and future applications have also been discussed in this review.

The dynamic monitoring of cell death processes remains a significant challenge due to the scarcity of highly sensitive molecular tools. In this study, two hemicyanine-based probes (5a-5b) with D-π-A structures were developed for organelle-specific viscosity monitoring. Both probes exhibited correlation with the Förster-Hoffmann viscosity-dependent relationship (R > 0.

Inorganic halide perovskites have been the subject of intensive research for their unique properties. Most current research focuses on halide ion exchange to modify the luminescence band gap and optical features. They are obtained mainly in colloids or thin layers, resulting in small grains with a narrow distribution.

Near-infrared (NIR) emitting materials underpin emerging medical diagnostics and therapeutic bionanotechnologies. Conjugated polymer nanoparticles offer unique advantages due to their remarkable absorption cross-sections, photostability, synthetic tunability, and biocompatibility. Despite the vast library of NIR-absorbing conjugated polymers, relatively few narrow bandgap structures have been explored for NIR imaging.

Nitric oxide (NO) and methylglyoxal (MGO) play a vital part in maintaining redox homeostasis, modulating substances, and signal transduction. Fluctuations in these signaling molecules are closely associated with various pathological processes. However, due to the absence of appropriate multifunctional fluorescent sensors, concurrent identification of NO and MGO has not been achieved in inflammatory diseases.
