Autor: Tiago Palmeira, David S. Conceição, Diana P. Ferreira, Carla C. Ferreira, Luís F. Vieira Ferreira, Mário N. Berberan-Santos

Publikováno v: Journal of Photochemistry and Photobiology, Vol 20, Iss , Pp 100226- (2024)

A simple method for obtaining triplet-triplet absorption (TTA) spectra and triplet state (T1) lifetimes of long-lived triplets is presented and demonstrated with the polycyclic aromatic hydrocarbon coronene (both normal and perdeuterated forms) in a

Spectroscopic Analysis of Parathyroid and Thyroid Tissues by Ground-State diffuse Reflectance and Laser Induced Luminescence: a Preliminary Report

Autor: Carlos, Serra, João, Serra, Isabel L, Ferreira Machado, Luís F, Vieira Ferreira

Publikováno v: Journal of fluorescence. 31(5)

Intraoperative discrimination of thyroid and parathyroid tissues is fundamental in thyroid surgery. Recent fluorescence studies have shown stronger NIR emission in parathyroid tissue than in thyroid tissue, presenting a potential avenue for the devel

Photophysical Studies of a New Water Soluble Indocarbocyanine Dye Adsorbed onto Microcrystalline Cellulose and b-Cyclodextrin

Autor: Luis F. Vieira Ferreira, Diana P. Ferreira, David S. Conceição, Paulo Almeida, Anabela S. Oliveira, Reda M. El-Shishtawy

Publikováno v: Molecules, Vol 18, Iss 5, Pp 5648-5668 (2013)

A water-soluble indocarbocyanine dye was synthesized and its photophysics were studied for the first time on two solid hosts, microcrystalline cellulose and b-cyclodextrin, as well as in homogeneous media. The inclusion of the indocarbocyanine moiety
