Research progress of near-infrared fluorescence probes based on indole heptamethine cyanine dyes in vivo and in vitro

open access: yesBMC Chemistry, 2020
Near-infrared (NIR) fluorescence imaging is a noninvasive technique that provides numerous advantages for the real-time in vivo monitoring of biological information in living subjects without the use of ionizing radiation. Near-infrared fluorescent (NIRF)

Two-Photon Absorption: An Open Door to the NIR-II Biological Window?

open access: yesFrontiers in Chemistry, 2022
The way in which photons travel through biological tissues and subsequently become scattered or absorbed is a key limitation for traditional optical medical imaging techniques using visible light.

Green fluorescent protein-based monitoring of endoplasmic reticulum redox poise [PDF]

open access: yes, 2013
Pathological endoplasmic reticulum (ER) stress is tightly linked to the accumulation of reactive oxidants, which can be both upstream and downstream of ER stress.

FLIP: FLuorescence Imaging Pipeline for field-based chlorophyll fluorescence images

open access: yesSoftwareX, 2021
Photosynthesis is one of the most important biological reactions on earth providing oxygen and food for humanity. As global populations rise and arable land decreases, crops need to become more efficient at photosynthetic processes, particularly utilizing absorbed light energy.

The Application of Nucleic Acid Probe–Based Fluorescent Sensing and Imaging in Cancer Diagnosis and Therapy

open access: yesFrontiers in Chemistry, 2021
It is well known that cancer incidence and death rates have been growing, but the development of cancer theranostics and therapeutics has been a challenging work. Recently, nucleic acid probe–based fluorescent sensing and imaging have achieved remarkable

Temporal resolution in fluorescence imaging [PDF]

open access: yesFrontiers in Molecular Biosciences, 2014
Temporal resolution is a key factor for imaging rapidly occurring events in biology. In this feature article, I investigate an approximate estimate for determining the temporal resolution limit. The condition that led to this limit is, the time taken by the ensemble (99.9%) of excited molecules to relax to ground state, assuming all the emitted photons

Imaging living obligate anaerobic bacteria with bilin-binding fluorescent proteins

open access: yesCurrent Research in Microbial Sciences, 2020
Fluorescent tools such as green fluorescent protein (GFP) have been used extensively as reporters in biochemistry and microbiology, but GFP and other conventional fluorescent proteins are restricted to aerobic environments.

A Versatile Pep-CPDs Nanoprobe for Rapid Detection of mTBI Biomarker in Clinical Instances and Safe Fluorescence Imaging In Vivo for Improved Weight-Drop Mouse Model

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
Mild traumatic brain injury (mTBI) is the most common form of traumatic brain injury; however, it is the most difficult to be accurately identified in the early stage because it lacks more reliable biomarkers and detection methods.

Comparison of noninvasive fluorescent and bioluminescent small animal optical imaging

open access: yesBioTechniques, 2003
Optical imaging is a modality that is cost-effective, rapid, easy to use, and can be readily applied to studying disease processes and biology in vivo. For this study, we used a green fluorescent protein (GFP)- and luciferase-expressing mouse tumor model
