-
(American Scientific Publishers, 2013)With the purpose of obtaining stable and non-toxic nanocomposites with potential biomedical applications we coated gold nanoparticles (AuNP) with chitosan (CHI) and CHI grafted with poly(Nisopropilacrylamide) (PNIPAAm) and ...
-
(American Scientific Publishers, 2013)There has been an increase in the research towards the use of nanoparticles as a promising tool for nanomedicine, from imagenology, drug and gene delivery, to phototherapy. Little is known regarding the interaction between ...
-
(2014)The present study is focused on the characterization of the interaction between (-)-epigallocatechingallate (EGCG) and cyclodextrins like β-cyclodextrin (βCD), heptakis(2,6 di-O-methyl)-β-cyclodextrin (DMβCD), and ...
-
(2012)Potato chips were classified in quality categories according to their color after frying at oil temperatures (120, 140, 160, and 180 ± 1 °C) and undergoing some pre-treatments (control or unblanching, blanching, and blanching ...
-
(Sociedad Chilena de Quimica, 2013)As (III) was determined by differential pulse polarography (DPP) in 1 mol L-1 HCl as supporting electrolyte. For quantification, the -0.35 V peak (versus Ag/AgCl) was chosen. The obtained detection and quantification limits ...
-
(2012)We report the adsorptive voltammetric determination of nifedipine on multiwalled carbon nanotubes (MWCNT)-modified glassy carbon electrode (GCE). Nifedipine was adsorbed on the MWCNT and then reduced using linear sweep and ...
-
(2014)In this paper, for the first time, an electro-analytical method based on the direct adsorption of double-stranded deoxyribonucleic acid (dsDNA) at glassy carbon electrode modified with ethylendiamine (eda)functionalized ...
-
(2013)A novel ORAC (oxygen radical absorbance capacity) assay to assess antioxidant capacity of phenolic compounds in near-gastric conditions (pH 2.0) is presented. AAPH (2,2'-azo-bis(2-amidinopropane)dihydrochloride) was used ...
-
(Taylor and Francis Inc., 2013)Despite recent scientific and technological advances, cardiovascular disease remains the leading cause of morbidity and mortality worldwide. Autophagy, an evolutionarily ancient response to cellular stress, has been ...
-
(2013)O objetivo deste estudo foi utilizar a técnica de difusão em filmes finos por gradiente de concentração (DGT) para a avaliação da disponibilidade de cobre em solos com elevados níveis do metal, que foi alterado com ...
-
(2014)The stopping power of palladium for protons has been measured using the transmission method with an overall uncertainty of around 5% over the energy range Ep=(0.300-3.100) MeV. These stopping power data are then compared ...
-
(2013)This paper describes the investigation and development of a novel magnetic drug delivery nanosystem (labeled as MO-20) for cancer therapy. The drug employed was oncocalyxone A (onco A), which was isolated from Auxemma ...
-
(Sociedad Chilena de Quimica, 2013)In recent years there has been a great demand for rare earth metals because of their unique physical and chemical properties as new constituents for electronic, optical and magnetic devices. Because of their extremely ...
-
(2013)In the structure of the title compound, {[Cu-2(C10H2O8)-(H2O)(6)]center dot 4H(2)O}(n), the benzene-1,2,4,5-tetracarboxylate ligand, (btec)(4-), is located on a crystallographic inversion centre in a 4-coordination mode. ...
-
(Sociedad Chilena de Quimica, 2013)Silicone rod extraction (SR) is a siloxane-based methodology for the extraction of organic pollutants from aqueous samples with similar principle extraction as the stir bar sorptive extraction (SBSE). In this study the SR ...
-
(2013)In the present paper a copper(II) phosphovanadate is presented and formulated as [Cu-6(phen)(6)((VO2)-O-v)(6) (PO4)(6)((VO2HO)-O-v)(3)] (1a). This compound was obtained by hydrothermal synthesis and crystallizes in the ...
-
(2013)In this work, a new method to quantify nitrofurantoin in aqueous media using a flow injection system connected to commercially available screen-printed carbon nanofibers was developed. A pretreatment of the screen-printed ...
-
(2013)A series of novel hydroxy-coumarin-chalcone hybrid compounds 2a-i has been synthesized by employing a simple and efficient methodology. An electrochemical characterization using cyclic voltammetry and ESR spectroscopy were ...
-
(2013)The construction and evaluation of an all-solid-state type electrode selective to nitrate based on poly(vinyl chloride) (PVC) as polymeric membrane, diethyl phthalate as plasticizer and tetradecilammonium nitrate (TDAN) ...
-
(2013)In light of the increasing use of nanotechnology in food production, consumer acceptance of sunflower oil produced with nanotechnology or from genetically modified (GM) plants and the conventionally produced raw materials ...
