Effective replacement of cetyltrimethylammonium bromide (CTAB) by mercaptoalkanoic acids on gold nanorod (AuNR) surfaces in aqueous solutions
Del Caño-Ochoa, Rafael; Gisbert-González, José M.; González Rodríguez, José; Sánchez-Obrero, Guadalupe; Madueño, Rafael; Blázquez, Manuel; Pineda, Teresa (Royal Society of Chemistry, 2020)The highly packed cetyltrimethylammonium bromide (CTAB) bilayer built up on the surface of gold nanorods (AuNRs) when synthetized by the seed-mediated procedure hampers the complete ligand exchange under experimental ... -
Electrochemiluminescent nanostructured DNA biosensor for SARS-CoV-2 detection
Gutiérrez-Gálvez, Laura; Del Caño-Ochoa, Rafael; Menéndez-Luque, Iris; García-Nieto, Daniel; Rodríguez-Peña, Micaela; Luna, Mónica; Pineda, Teresa; Pariente, Félix; García-Mendiola, Tania; Lorenzo, Encarnación (Elsevier, 2022)This work focuses on the development of an electrochemiluminescent nanostructured DNA biosensor for SARSCoV- 2 detection. Gold nanomaterials (AuNMs), specifically, a mixture of gold nanotriangles (AuNTs) and gold nanoparticles ... -
Hemoglobin becomes electroactive upon interaction with surface-protected Au nanoparticles
Del Caño-Ochoa, Rafael; Mateus, Lucía; Sánchez-Obrero, Guadalupe; Sevilla, José Manuel; Madueño, Rafael; Blázquez, Manuel; Pineda, Teresa (Elsevier, 2018)In this work, we report on the electrochemical behavior of bioconjugates prepared with gold nanoparticles (AuNP) capped with three different molecular layers (citrate anions, 6-mercaptopurine and ω-mercaptoundecanoic acid) ... -
Hemoglobin bioconjugates with surface-protected gold nanoparticles in aqueous media: The stability depends on solution pH and protein properties
Del Caño-Ochoa, Rafael; Mateus, Lucía; Sánchez-Obrero, Guadalupe; Sevilla, José Manuel; Madueño, Rafael; Blázquez, Manuel; Pineda, Teresa (Elsevier, 2017)The identification of the factors that dictate the formation and physicochemical properties of protein-nanomaterial bioconjugates are important to understand their behavior in biological systems. The present work deals ... -
