Colorimetric detection of normetanephrine, a pheochromocytoma biomarker, using bifunctionalised gold nanoparticles.
Tania M. Godoy-Reyes,Ana M. Costero,Pablo Gaviña,Pablo Gaviña,Ramón Martínez-Máñez,Félix Sancenón +5 more
TL;DR: The colorimetric probe was highly selective towards normetanephrine and no color changes were observed in the presence of other neurotransmitter metabolites such as homovanillic acid (HVA) (dopamine metabolite), 5-hydroxyindoleacetic acid (5-HIAA) (serotonin metabolite) or other biomolecules present in urine such as glucose, uric acid, and urea.

Humidity-Dependent Reversible Transitions in Gold Nanoparticle Superlattices
TL;DR: In this article, the changes in interparticle spacing upon hydration and dehydration of drop-cast films of hydrophilic gold nanoparticles (GNP) have been measured in situ with nanometer resolution using WetSTEM and ESEM.
Journal ArticleDOI
On-water synthesis of phenols using biogenic Cu2O nanoparticles without using H2O2
TL;DR: In this article, the average size of the nanoparticles is 7.6 µm and they have excellent catalytic activity in the ipso-hydroxylation of arylboronic acids without using H2O2.

Controlled nucleation for the regulation of the particle size in monodisperse gold suspensions
TL;DR: In this article, a series of monodisperse suspensions of the same chemical composition but of rather different particle sizes was used to study particle size dependent phenomena, such as Brownian motion, light scattering, sedimentation and electrophoresis of small particles.
Journal ArticleDOI
Chemistry and properties of nanocrystals of different shapes.
TL;DR: The interest in nanoscale materials stems from the fact that new properties are acquired at this length scale and, equally important, that these properties are equally important.
