"Snorkelling" vs. "diving" in mixed micelles probed by means of a molecular bathymeter

Rodríguez Muñiz, Gemma María; Gomez Mendoza, Miguel; Nuin Pla, Neus Edurne; Andreu Ros, María Inmaculada; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (The Royal Society of Chemistry, 2017)

[EN] A photoactive bathymeter based on a carboxylic acid moiety covalently linked to a signalling methoxynaphthalene (MNP) fluorophore has been designed to prove the concept of "snorkelling" vs. "diving" in mixed micelles ...
Controlled Synthesis of Up-Conversion NaYF4:Yb,Tm Nanoparticles for Drug Release under Near IR-Light Therapy

Moyano Rodríguez, Edelweiss; Gomez-Mendoza, Miguel; Pérez-Ruiz, Raúl; Peñín, Beatriz; Sampedro, Diego; Caamaño, Antonio; de la Peña O Shea, Víctor A. (MDPI AG, 2021-12)

[EN] Up-Conversion materials have received great attention in drug delivery applications in recent years. A specifically emerging field includes the development of strategies focusing on photon processes that promote the ...
Dansyl derivatives of cholic acid as tools to build speciation diagrams for sodium chotale aggregation

Gómez Mendoza, Miguel; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (American Chemical Society, 2011-03-15)

Three ¿uorescent cholic acid derivatives incorporating the dansyl chromophore at positions 3R, 3ß, and 7Rhave been successfully employed to build the speciation diagram of sodium cholate by means of steady-state and ...
Dansyl-labeled cholic acid as a tool to build speciation diagrams for the aggregation of bile acids

Gómez Mendoza, Miguel; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (American Chemical Society, 2012-12-27)

Bile acids (BAs) are a family of natural steroids biosynthesized from cholesterol in the liver that tend to form aggregates in solution. A fluorescent derivative of cholic acid, namely 3 alpha-Dns-ChA, was employed as a ...
Degradation of Benzotriazole UV-stabilizers in the presence of organic photosensitizers and visible light: A time-resolved mechanistic study

Pavanello, Alice; Gomez-Mendoza, Miguel; de la Peña O'Shea, Víctor; Miranda Alonso, Miguel Ángel; Marín García, Mª Luisa (Elsevier, 2022-04)

[EN] Benzotriazole UV-stabilizers (BUVSs) are commonly used in industry as solar filters, due to their strong UV light absorption. Because of their extended usage, environmental contamination of waters due to BUVSs constitutes ...
Generation of the Thymine Triplet State by Through-Bond Energy Transfer

Miró, Paula; Gomez-Mendoza, Miguel; SASTRE NAVARRO, GERMAN IGNACIO; Cuquerella Alabort, Maria Consuelo; Miranda Alonso, Miguel Ángel; Marín García, Mª Luisa (John Wiley & Sons, 2019-05-17)

[EN] Benzophenone (BP) and drugs containing the BP chromophore, such as the non-steroidal anti-inflammatory drug ketoprofen, have been widely reported as DNA photo-sensitizers through triplet-triplet energy transfer (TTET). ...
Influence of drug encapsulation within mixed micelles on the excited state dynamics and accessibility to ionic quenchers

Nuin Plá, Neus Edurne; Gómez Mendoza, Miguel; Marín García, Mª Luisa; Andreu Ros, María Inmaculada; Miranda Alonso, Miguel Ángel (American Chemical Society, 2013-08-15)

Photophysical techniques, specifically time-resolved fluorescence and laser flash photolysis, have proven to be noninvasive, straightforward, and valuable tools to demonstrate how drug encapsulation into biomimetic mixed ...
New photoactive compounds to probe cholic acid and cholesterol inside mixed micelles

Nuin Plá, Neus Edurne; Gómez Mendoza, Miguel; Andreu Ros, María Inmaculada; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (American Chemical Society, 2013-01-18)

New photoactive dyads have been synthesized by derivatization of cholic acid (CA) or cholesterol (Ch). These compounds have proven to be efficient tools to monitor incorporation of CA and Ch to mixed micelles (MM) and to ...
Nuevas sondas fotoactivas para el estudio de sistemas supramoleculares basados en ácidos biliares

Gómez Mendoza, Miguel (Universitat Politècnica de València, 2014-01-07)

Los ácidos biliares son estereoides biosintetizados en los hepatocitos del hígado que actúan como tensoactivos para facilitar la digestión de grasas, colesterol y lípidos mediante la formación de agregados y micelas ...
Photoactive bile salts with critical micellar concentration in the micromolar range

Gómez Mendoza, Miguel; Marín García, Mª Luisa; Miranda Alonso, Miguel Ángel (Royal Society of Chemistry, 2016-05-14)

The aggregation behavior of bile salts is strongly dependent on the number of hydroxyl groups. Thus, cholic acid (CA), with three hydroxyls, starts forming aggregates at 15 mM, while deoxycholic, chenodeoxycholic or ...
