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.
