Gold, Silver and Platinum Nanoparticles: From New Synthetic Routes to Sensing, ...
Fernández-Lodeiro, AdriánGold, Silver and Platinum metallic nanoparticles have emerged as powerful tools with a wide array of applications in different fields, such as biomedicine, catalysis, and environmental sciences. The modification of nanoparticles´ metal composition, size, and shape lead to totally different properties of the nanomaterial. This tunable versatility is responsible for the vast array of applications of nanomaterials...
From yellow to pink using a fluorimetric and colorimetric pyrene derivative and...
Pinheiro, Daniela; Castro, Catherine S. de; Melo, J. Sérgio Seixas de; Oliveira, Elisabete; Nuñez, Cristina; Fernández-Lodeiro, Adrián1st International Caparica Conference on Chromogenic and Emissive Materials; A new simple and multifunctional fluorescent probe based on pyrene linked through an imine bond to a hydroxyphenol unit was synthesised, fully characterized and investigated in solution. Additionally, its behaviour in the presence of several ions (H+, Zn2+, Cd2+, Cu2+, Ni2+, Pb2+, Fe2+, Hg2+ and Al3+) was investigated in CH2Cl2. It was...
Spectroscopic and photophysical studies of a naphthalene-based emissive probe f...
Castro, Catherine S. de; Melo, J. Sérgio Seixas de; Fernández-Lodeiro, Adrián; Núñez, Cristina; Lodeiro, CarlosA comprehensive photophysical characterization of a bis-naphthalene derivative, L, was carried out in acetonitrile, using UV–Vis absorption, steady-state and time-resolved emission spectroscopy. It was found that in the 250–400 nm region, the absorption spectra showed two bands with maxima at ~ 220 nm and ~ 292 nm whereas the emission spectrum showed a band settled between 300 and 550 nm. A detailed time-resolv...
