Structure-behavior study of a family of "hybrid cyanine" dyes which exhibit inverted solvatochromism
(2016)
The inverted solvatochromism of twenty dyes containing an electron-donor phenolate conjugated with an electron-withdrawing nitro-substituted phenyl ring was analyzed in terms of the dye structure and substituents. Structural ...
NIR fluorescent biotinylated cyanine dye: optical properties and combination with quantum dots as a potential sensing device
(Royal Society of Chemistry, 2012-08-29)
We present a water soluble and fluorescent biotinylated probe derived from a carbocyanine dye. A high efficiency of energy transfer was measured when the dyes were placed on the surface of streptavidin conjugated Quantum ...
A Highly Sensitive Fluorogenic Probe for Imaging Glycoproteins and Mucine Activity in Live Cells in the Near-Infrared Region
(Wiley VCH Verlag, 2018-04)
A novel fluorescent molecular probe is reported, which is able to detect glycoproteins, especially mucins, with high sensitivity and with a turn-on response along with a large Stokes shift (>130 nm), within the biologically ...
Benzoxaboroles as dynamic covalent receptors for bioconjugation and transport of nucleosides and related drugs: proof of action in HeLa cells
(Academic Press Inc Elsevier Science, 2019-06)
In this work we describe not previously explored binding studies on the reversible interaction of benzoxaborole with ligands of medical and pharmaceutical interest such as nucleosidic drugs gemcitabine and capecitabine, ...
Exploiting cyanine dye J-aggregates/monomer equilibrium in hydrophobic protein pockets for efficient multi-step phototherapy: An innovative concept for smart nanotheranostics
(Royal Society of Chemistry, 2021-04)
After several decades of development in the field of near-infrared (NIR) dyes for photothermal therapy (PTT), indocyanine green (ICG) still remains the only FDA-approved NIR contrast agent. However, upon NIR light irradiation ...
A silica supported tricarbocyanine based pH nanosensor with a large Stokes shift and a near infrared fluorescence response: performance in vitro and in live cells
(Royal Society of Chemistry, 2017-05)
We report the synthesis of a near-infrared (NIR) fluorescent pHprobe with a remarkable Stokes shift reported (∼ 135 nm) basedon a tricarbocyanine (Cy-PIP). The fluorescent molecule wasanchored to SiO2 nanoparticles ...
Polymethine cyanine dyes in beta-cyclodextrin solution: multiple equilibria and chemical oxidation
(JOHN WILEY & SONS LTD, 2010)
Absorption and fluorescence spectroscopy, electrochemical techniques, and semiempirical calculations were employed to characterize the multiple complexation equilibria between two polymethine cyanine dyes (IR-786 and ...
