Development of a gas chromatography-mass spectrometry method for the determination of pesticides in gaseous and particulate phases in the atmosphere

Borrás García, Esther Mª; Sánchez, P.; Muñoz, A.; Tortajada Genaro, Luis Antonio (ELSEVIER SCIENCE BV, 2011)

[EN] A reliable multi-residue method for determining gaseous and particulate phase pesticides in atmospheric samples has been developed. This method, based on full scan gas chromatography-mass spectrometry (GC-MS), allowed ...
Enhancement of the catalytic activity of supported gold nanoparticles for the fenton reaction by light

Navalón Oltra, Sergio; De Miguel de la Torre, Maykel; Martín González, Roberto; Alvaro Rodríguez, Maria Mercedes; García Gómez, Hermenegildo (American Chemical Society, 2011)

[EN] Laser flash photolysis of supported gold nanopar-ticles exciting at the surface plasmon band (532 nm) has allowed in the case of Au/CeO 2 and Au/OH-npD (OH-npD: Fenton-treated diamond nanoparticles) detection of ...
Enzyme-mediated controlled release systems by anchoring peptide sequences on mesoporous silica supports

Coll Merino, Mª Carmen; Mondragón Martínez, Laura; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Marcos Martínez, María Dolores; Soto Camino, Juan; Amoros del Toro, Pedro Jose; Pérez Payá, Enrique (Wiley-VCH Verlag, 2011-02-01)

Gated community: Peptides anchored to the surface of silica mesoporous supports by a valid procedure act as gatekeepers. In this way, "zero release" supports that selectively deliver the cargo in the presence of a suitable ...
Finely tuned temperature-controlled cargo release using paraffin-capped mesoporous silica nanoparticles

Aznar Gimeno, Elena; Mondragón Martínez, Laura; Ros-Lis, José Vicente; Sancenón Galarza, Félix; Marcos Martínez, María Dolores; Martínez Mañez, Ramón; Soto Camino, Juan; Pérez Payá, Enrique; AMOROS DEL TORO, PEDRO (Wiley-VCH Verlag, 2011-09-27)

Trapped: Mesoporous silica nanoparticles were loaded with a fluorescent guest and functionalized with octadecyltrimethoxysilane. The alkyl chains interact with paraffins, which build a hydrophobic layer around the particle ...
Highly selective and sensitive chromo-fluorogenic detection of the Tetryl explosive using functional silica nanoparticles

Salinas Soler, Yolanda; Climent Terol, Estela; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Marcos Martínez, María Dolores; Soto Camino, Juan; Costero, Ana M.; Gil Grau, Salvador; Parra Álvarez, Margarita; Perez de Diego, Alberto (Royal Society of Chemistry, 2011)

Silica nanoparticles containing polyamines and thiol groups have been used as probes for the selective detection of Tetryl. © 2011 The Royal Society of Chemistry.
In vivo toxicity assessment of eugenol and vanillin-functionalised silica particles using Caenorhabditis elegans

Fuentes López, Cristina; VERDÚ AMAT, SAMUEL; Fuentes López, Ana; Ruiz, María José; Barat Baviera, José Manuel (Elsevier, 2022-06-15)

[EN] The toxicological properties of different silica particles functionalised with essential oil components (EOCs) were herein assessed using the in vivo model C. elegans. In particular, the effects of the acute and ...
Selective and sensitive chromo-fluorogenic sensing of anionic surfactants in water using functionalised silica nanoparticles

Climent Terol, Estela; Giménez Morales, Cristina; Marcos Martínez, María Dolores; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Soto Camino, Juan (Royal Society of Chemistry, 2011)

A new chromo-fluorogenic sensing protocol for anionic surfactants in aqueous environments using silica functionalised nanoparticles containing imidazolium and thiol groups has been developed. © 2011 The Royal Society of Chemistry.
Sensitive and selective chromogenic sensing of carbon monoxide via reversible axial CO coordination in binuclear rhodium complexes

Moragues Pons, María Esperanza; Esteban Moreno, Julio; Ros-Lis, José Vicente; Martínez Mañez, Ramón; Marcos Martínez, María Dolores; Martínez, Manuel; Soto Camino, Juan; Sancenón Galarza, Félix (American Chemical Society, 2011-10)

The study of probes for CO sensing of a family of binuclear rhodium(II) compounds of general formula [Rh 2{(XC 6H 3)P(XC 6H 4)} n(O 2CR) 4-n]·L 2 containing one or two metalated phosphines (in a head-to-tail arrangement) ...
Silica nanoparticles functionalised with cation coordination sites and fluorophores for the differential sensing of anions in a quencher displacement assay (QDA)

Calero Rodríguez, María del Pilar; Hecht, Mandy; Martínez Mañez, Ramón; Sancenón Galarza, Félix; Soto Camino, Juan; Vivancos, José-Luís; Rurack, Knut (Royal Society of Chemistry, 2011)

In conjunction with quenching metal ions, silica nanoparticles carrying terpyridine coordination sites and sulforhodamine B signalling units were employed for the differential fluorometric recognition of anions. © 2011 The ...
