Electronic effects in CdSe/ZnS quantum dots conjugated to Interleukin 10 antibodies

Torchynska T.V., Casas Espinola J.L., Douda J., López de la Luz O.S., Instituto Politecnico Nacional, MX

Photoluminescence (PL) and Raman scattering spectra of none- and bio-conjugated CdSe/ZnS and CdSeTe/ZnS quantum dots (QDs) have been studied. QDs, characterized by emission at 605, 655 and 705nm, have been conjugated with anti Interleukin 10 [...]

Stimuli-responsive nanogels by e-beam irradiation of dilute aqueous micellar solutions: Nanogels with pH controlled LCST

Picos-Corrales L.A., Licea-Claveríe A., Arndt K.-F., Instituto Tecnologico de Tijuana, MX

Nanogels have attracted growing interest owing to their potential for applications in drug delivery systems. In this work, responsive nanogels based on amphiphilic block copolymers crosslinked in the micellar state were prepared by electron beam [...]

Synthesis and Characterization of Nickel Ferrite (NiFe2O4) nanoparticles with Silver Addition for H2S gas detectors

Domínguez-Ruiz N., García-Casilla P.E., Hernández-Paz J.F., Ramos-Murillo M., Ambrosio-Lazaro R.C., Universidad Autonoma de Ciudad Juarez, MX

The objective of this work is to study the influence of silver as additive in nickel ferrite sensors to improve the hydrogen sulfide detection sensibility. Sensors made of NiFe2O4 nanoparticles with and without Silver (3 [...]

Stability of Functionalized Magnetic Particles in a Physiologic Fluid

Baca Ramos K., Martínez Pérez C.A., Camacho Montes H., Olivas Armendáriz I., Martel A., García-Casillas P.E., Universidad Autonoma de Ciudad Juarez, MX

Magnetic materials are widely used in biomedical applications such as magnetic separation, magnetic resonance imaging, drug delivery and hyperthermia. In these applications the nanoparticles are functionalized in a core/shell type with polymeric materials which contains [...]

Interaction between Volatile Organic Compounds and Functional Monomers in Molecularly Imprinted Materials

Luga C., Ortíz E., Noreña L., Universidad Autónoma Metropolitana, MX

Molecularly imprinted polymers (MIPs) have been playing an increasingly important role in volatile organic compound (VOC) sensing for air quality control. The unique feature of these materials is their biomimetic molecular recognition functionality. Theoretical chemistry [...]

Heterogeneous Catalyzed Oxidative Degradation of Indigo: A Theoretical and Experimental Study

Luga C., Solís-Correa H., Universidad Autónoma Metropolitana, MX

Almost fifteen percent of the total world production of dyes is lost during the dyeing process and is released in the textile effluents. Removal of colour and organics by photocatalytic degradation is emerging as an [...]

Molar variation of water: alkoxy in the preparation of SiO2-DA materials and its effect on dopamine release from an implantable reservoir in the brain

Lopez T., Esquivel D., Garcia E., National Institute of Neurology and Neurosurgery, MX

In the present work we report the dopamine (DA) molecules stabilization in the network of nanostructured silica materials with the objective of using these as reservoirs of DA release in the brain. For this purpose [...]

Nanosized titania reservoirs for epilepsy treatment

Kozina A., Espinoza K.A., Ortiz-Islas E., Rivero I.A., Lopez T., Instituto Nacional de Neurologia y Neurocirugia ‘MVS’, MX

Around 50 million people in the world suffer from epilepsy. Although there is no cure for this disease, with the right type and dosage of anti-epileptic medication the majority of patients can have their seizures [...]
