In vivo EDXRF scanning analysis of human nail
(2014-09)
This paper presents the results of a new technique forin vivoenergy dispersive X-rayfluorescence (EDXRF) scan analysis, applied to humanfingernails. The scan employs a specially designed EDXRF spectrometer, which allows a ...
Evaluation of EDXRF configurations to improve the limit of detection and exposure for in vivo quantification of gadolinium in tumor tissue
(Pergamon-Elsevier Science Ltd, 2016-05)
In this paper the configuration of an Energy Dispersive X-Ray Fluorescence (EDXRF) system optimized for in vivo quantification of gadolinium in tumor tissue was studied. The system was configured using XMI-MSIM software ...
Optimization of the sensitivity/doses relationship for a bench-top EDXRF system used for in vivo quantification of gold nanoparticles
(Pergamon-Elsevier Science Ltd, 2017-11)
The present work is devoted to optimizing the sensitivity-doses relationship of a bench-top EDXRF system, with the aim of achieving a detection limit of 0.010 mg/ml of gold nanoparticles in tumor tissue (clinical values ...
Optimized EDXRF system for simultaneous detection of gold and silver nanoparticles in tumor phantom
(Pergamon-Elsevier Science Ltd, 2019-12-24)
An energy-dispersive X-ray fluorescence system (EDXRF) was optimized for simultaneous detection of gold and silver nanoparticles inside water-equivalent phantoms applied to theranostics. The optimization process was carried ...
Optimal configuration for detection of gold nanoparticles in tumors using Kβ X-ray fluorescence line
(Pergamon-Elsevier Science Ltd, 2015-12)
This study examines the increase in the capacity to detect gold nanoparticles in tumor tissue using X-rays from orthovoltage sources. The analyzed methodology considered aspects of geometry and composition in accordance ...
A high-sensitivity and low dose energy-dispersive X-ray fluorescence system for identification of gadolium accumulations in planar X-ray fluorescence images
(Pergamon-Elsevier Science Ltd, 2019-09)
A new technique, based on in-vivo energy dispersive X-ray fluorescence (EDXRF), has been developed to gadolinium (Gd)concentrations identification in planar X-ray fluorescence (XRF)images. Higher signal-to-noise (SNR)ratios ...
Pehuén (Araucaria araucana) seed residues are a valuable source of natural antioxidants with nutraceutical, chemoprotective and metal corrosion-inhibiting properties
(Academic Press Inc Elsevier Science, 2020-11)
In the last decade, green chemistry has been attracting great interest in many contexts, including, among others, natural antioxidants. However, only a few works deal with natural residue extracts and biowaste, which could ...
Selenium absorption kinetics and localization in cowpea genotypes using XRF technique associated with physiological and biochemical responses
(Universidade Estadual Paulista (Unesp), 2022-02-10)
O selênio (Se) é um elemento essencial para humanos e animais e benéfico para as plantas. Os solos são pobres em Se, tornando a dieta da população deficiente. A biofortificação agronômica é uma estratégia para aumentar os ...
