    • 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 ...

    • Distinct thermoresponsive behaviour of oligo- and poly-ethylene glycol protected gold nanoparticles in concentrated salt solutions 

      Chávez, Miriam; Fernández-Merino, Ángela; Sánchez-Obrero, Guadalupe; Madueño, Rafael; Sevilla, José Manuel; Blázquez, Manuel; Pineda, Teresa (Royal Society of Chemistry, 2021)
      In this work, the methoxy terminated oligo- and polyethylene glycol of different chain lengths (EGn, n ¼ 7, 18, 45 and 136) is grafted on AuNP surfaces under conditions where they attain maximum grafting densities. These ...

    • 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) ...

    • Methylene Blue functionalized carbon nanodots combined with different shape gold nanostructures for sensitive and selective SARS-CoV-2 sensing 

      Pina-Coronado, Clara; Martínez-Sobrino, Álvaro; Gutiérrez-Gálvez, Laura; Del Caño-Ochoa, Rafael; Martínez-Periñán, Emiliano; García-Nieto, Daniel; Rodríguez-Peña, Micaela; Luna, M.; Milán-Rois, Paula; Castellanos, Milagros; Abreu, Melanie; Cantón, Rafael; Galán, Juan Carlos; Pineda, Teresa; Pariente, Félix; Somoza, Álvaro; García-Mendiola, Tania; Miranda, Rodolfo; Lorenzo, Encarnación (Elsevier, 2022)
      The development of DNA-sensing platforms based on new synthetized Methylene Blue functionalized carbon nanodots combined with different shape gold nanostructures (AuNs), as a new pathway to develop a selective and sensitive ...
