A photoinduced electron transfer-based nanoprobe as a marker of acidic organelles in mammalian cells
Marín, María J.; Galindo, Francisco; Thomas, Paul; Wileman, Tom; Russell, David A. Springer (2013-07)Photoinduced electron transfer (PET)-based molecular probes have been successfully used for the intracelular imaging of the pH of acidic organelles. In this study, we describe the synthesis and characterization of a novel ... -
Fluorescence of 1,2-Diaminoanthraquinone and its Nitric Oxide Reaction Product within Macrophage Cells
Marín, María J.; Thomas, Paul; Fabregat Tena, Víctor; Luis, Santiago V.; Russell, David A.; Galindo, Francisco Wiley-VCH (2011)Nitric oxide (NO) is involved in many biological processes. Aromatic ortho-diamine derivatives are commonly used in the fluorescence imaging of NO in living cells. ortho-diamino (o-diamino) compounds are believed to react ... -
Fluorescent macrocyclic probes with pendant functional groups as markers of acidic organelles within live cells
Wadhavane, Prashant Dinkar; Izquierdo Arcusa, María Ángeles; Lutters, Dennis; Burguete, M. Isabel; Marín, María J.; Russell, David A.; Galindo, Francisco; Luis, Santiago V. Royal Society of Chemistry (2014)A new family of acidity sensitive fluorescent macrocycles has been synthesized and fully characterized. Their photophysical properties including emission quantum yield and fluorescence lifetime have been determined. The ... -
Localized intracellular pH measurement using a ratiometric photoinduced electron-transfer-based nanosensor
Galindo, Francisco; Russell, David A.; Thomas, Paul; Marín Altaba, María Wiley (2012-09)Intracellular analysis: Changes in the concentration of hydrogen ions can lead to cellular dysfunction. Thus, quantification of the intracellular pH in localized compartments (see A and B) is important. A pH nanosensor ... -
Singlet oxygen generation using a porous monolithic polymer supported photosensitizer: potential application to the photodynamic destruction of melanoma cells
Burguete, M. Isabel; Galindo, Francisco; Gavara, Raquel; Luis, Santiago V.; Moreno, Miguel; Thomas, Paul; Russell, David A. Royal Society of Chemistry (2009-01)Photogeneration of singlet oxygen (1O2) by rose bengal is improved through the use of a porous monolithic polymer (PMP) as a support, as compared to a classic gel-type resin matrix. This type of monolithic polymeric ... -
The synthesis of new fluorescent bichromophoric compounds as ratiometric pH probes for intracellular measurements
Saura Centelles, Ana Vanessa; Marín, María J.; Burguete, M. Isabel; Russell, David A.; Galindo, Francisco; Luis, Santiago V. Royal Society of Chemistry (2015)Three different bichromophoric compounds (1–3) containing an aminomethyl anthracene moiety linked to a second chromophore (pyrene, 4-nitrobenzo-2-oxa-1,3-diazole (NBD) and dansyl) through a valinederived pseudopeptidic ...
