An Opto‐ and Thermal‐Rewrite PCM/CNF‐IR 780 Energy Storage Nanopaper with Mechanical Regulated Performance

Small, 2022
AbstractIn spite of efforts to fabricate self‐assembled energy storage nanopaper with potential applications in displays, greenhouses, and sensors, few studies have investigated their multiple stimuli‐sensitivities. Here, an opto‐ and thermal‐rewrite phase change material/cellulose nanofibril (PCM/CNF) energy storage nanopaper with mechanical regulated

Improved Photodynamic Therapy Based on Glutaminase Blockage via Tumor Membrane Coated CB‐839/IR‐780 Nanoparticles

Small, 2023
AbstractPhotodynamic therapy (PDT) has promising applications. However, the lethal function of reactive oxygen species (ROS) produced during PDT is typically limited. This restriction is induced by oxygen shortage in the tumor microenvironment due to tumor cell hypermetabolism and reductive chemicals overexpression in tumor tissues.

IR 780-loaded hyaluronic acid micelles for enhanced tumor-targeted photothermal therapy

Carbohydrate Polymers, 2018
In this study, we propose using IR 780-loaded, CD44-targeted hyaluronic acid-based micelles (HA-IR 780) for enhanced photothermal therapy (PTT) effects in tumors. Two kinds of HA-C18 micelles were synthesized from different C18 feed ratios with degree of substitution of 3% and 13% respectively.

Effects of Human Serum Albumin on the Fluorescence Intensity and Tumor Imaging Properties of IR‐780 Dye

Photochemistry and Photobiology, 2021
AbstractIR‐780 is a lipophilic dye with excellent optical and tumor imaging properties for early tumor diagnostics. Although the mechanism of tumor targeting has not been fully identified, the view that serum albumin plays an important role in tumor accumulation has been recognized.

Cyanine IR-780 for distinguishing 2-amino thiophenols from position isomers

Dyes and Pigments, 2016
Abstract Developing highly selective fluorescent probes for the determination of thiophenol is very significant due to its toxicity influence in biological system. In this work, we firstly found that the commercial available cyanine dye 3H-Indolium, 2-(2-(2-chloro-3-(2-(1,3-dihydro-3,3-dimethyl-1-propyl-2H-indol-2-ylidene)ethylidene)-1-cyclohexen-1 ...

AIEgens Conjugation Improves the Photothermal Efficacy and Near-Infrared Imaging of Heptamethine Cyanine IR-780

ACS Applied Materials & Interfaces, 2020
Near-infrared (NIR) fluorescent probes can deeply penetrate through tissues with little damage. To facilitate image-guided theranostics, researchers usually apply a desired amount of photosensitizers to achieve effective photothermal responses. However, these probes could easily suffer from low photostability and aggregated-caused quenching effect in ...

IR-780 dye loaded tumor targeting theranostic nanoparticles for NIR imaging and photothermal therapy

Biomaterials, 2013
IR-780 iodide is a near-infrared (NIR) fluorescence dye with higher and more stable fluorescence intensity than clinically applied dye indocyanine green (ICG). Meanwhile, IR-780 can be utilized in photothermal therapy with laser irradiation. IR-780 is an important theranostic agent but its lipophilicity limited its application.

Bio-nanoconjugates of lithocholic acid/IR 780 for ROS-mediated apoptosis and optoacoustic imaging applications in breast cancer

Colloids and Surfaces B: Biointerfaces, 2023
A new lithocholic acid/IR 780 conjugate (LIC) was designed and synthesized for theranostic applications in triple-negative breast cancer. Lithocholic acid is an antitumor biomacromolecule and acts via multiple molecular targets. IR 780 iodide is a fluorescent NIR organic dye researched as a photothermal agent in cancer therapy.

IR-780 dye can be used as a sonodynamic agent against breast tumor

2015 IEEE International Ultrasonics Symposium (IUS), 2015
Sonodynamic therapy (SDT) is developing as a new modality for cancer therapy through activating certain chemical sensitizers by ultrasound. The aim of this work was to introduce IR-780 iodide, a lipophilic cation heptamethine dye with peak absorption at 780 nm, as SDT agents for breast cancer treatment. The in vitro cellular uptake, cell viability, and
