Cirera B, Trukhina O, Björk J, Bottari G, Rodríguez-Fernández J, Martin-Jimenez A, Islyaikin MK, Otero R, Gallego JM, Miranda R, Torres T, Ecija D.
PMID: 28889740
J Am Chem Soc. 2017 Oct 11;139(40):14129-14136. doi: 10.1021/jacs.7b06406. Epub 2017 Sep 27.

Expanded porphyrins are large-cavity macrocycles with enormous potential in coordination chemistry, anion sensing, photodynamic therapy, and optoelectronics. In the last two decades, the surface science community has assessed the physicochemical properties of tetrapyrrolic-like macrocycles. However, to date, the sublimation,...

Nanoscale. 2015 Apr 21;7(15):6675-82. doi: 10.1039/c5nr00656b.

Here, we describe an electronically coupled hybrid material consisting of graphene oxide (GO) flakes and inorganic Cu(2-x)S nanocrystals (NCs) formed via a self-assembly route. As a result of the amphiphilic nature of the water-dispersible GO flakes, the hydrophobic Cu(2-x)S...

The effect of surface roughness on the plasmonic response of individual sub-micron gold spheres.

Phys Chem Chem Phys. 2009 Jul 28;11(28):5909-14. doi: 10.1039/b905200n. Epub 2009 May 15.

Nanoscale surface corrugation strongly determines the plasmonic response of gold nanoparticles with dimensions of several tens of nanometres. Scattering spectra of individual spheres with a rough surface were found to red-shift and broaden. The plasmon modes exhibited quadrupole damping,...

We report an easy approach for the synthesis of CdS Quantum Dots (CdS QDs) with high luminescence and temporal stability through the reaction of Cd(2+) and S(2-) in the presence of mercaptoacetic acid (MAA) as a capping reagent in...

Spatially-directed oxidation of gold nanoparticles by Au(III)-CTAB complexes.

The journal of physical chemistry. B

Rodríguez-Fernández J, Pérez-Juste J, Mulvaney P, Liz-Marzán LM.

J Phys Chem B. 2005 Aug 04;109(30):14257-61. doi: 10.1021/jp052516g.

Gold nanoparticles are readily oxidized by Au(III) in the presence of cetyl-trimethylammonium bromide (CTAB). Oxidation occurs preferentially at surface sites with higher curvature. Conversely, oxidation with cyanide ions in the absence of CTAB leads to uniform oxidation over the...

We have coated gold nanorods (NRs) with thermoresponsive microgel shells based on poly(N-isopropylacrylamide) (pNIPAM). We demonstrate by simultaneous laser-heating and optical extinction measurements that the Au NR cores can be simultaneously used as fast optothermal manipulators (switchers) and sensitive...
