Laser-induced breakdown spectroscopy (LIBS) and LA-ICP-MS (laser ablation inductively coupled plasma mass-spectrometry) were used for the detection of trace metals in a solid matrix consisting of KBr and two oxides. The results of both methods were compared to investigate the strengths and weaknesses of both methods. Most difficulties for quantification of LIBS data are related to matrix effect...

In the present study, a historical set of Late Roman glasses coming from a recently unearthed graveyard located in the small city of Cubas de la Sagra, within the Madrid region (Spain) was compositionally analysed using different techniques such as ultraviolet-visible (UV-Vis) and laser induced fluorescence (LIF) spectroscopies, X-ray fluorescence (XRF) and laser induced breakdown spectroscopy ...

BACKGROUND Molecular imaging is a fast emerging technology allowing noninvasive detection of vascular pathologies. However, imaging modalities offering high resolution currently do not allow real-time imaging. We hypothesized that contrast-enhanced ultrasound with microbubbles (MBs) selectively targeted to activated platelets would offer high-resolution, real-time molecular imaging of evolving ...

Many industrial activities require adequate and timely evaluation of material composition. Laser-induced breakdown spectroscopy (LIBS) has, in recent years, shown a great potential for rapid qualitative and quantitative chemical analysis of various materials. In this paper, we will illustrate the usefulness of the LIBS technique for elemental analysis at different scales: from depth profilometr...

Simple methods for the determination of elements in biological fluids have been developed. It is important to quantify accidental incorporation radionuclides during decommissioning work at nuclear power plants. Herein, we proposed simple preparations and uranium concentrations urine microbeam scanning particle induced X-ray emission (µ-PIXE) analysis a rat model. A droplet (1 µL) mixed solution...

This paper presents a technique for identification of solid materials by localized microwaves. A small hotspot (~1-mm) created by thermal-runaway instability on the material surface is further radiated by the localized microwaves hence ejecting a plasma plume. Its atomic emission spectrum is detected and analyzed by an optical spectrometer for element identification, as in the known laser-induc...

Introduction Laser-induced breakdown spectroscopy (LIBS) is considered one of the most convenient and efficient analytical techniques for trace elemental analysis in gases, solids, and liquids. Both non-invasive and non-destructive, LIBS requires little-to-no sample preparation and can easily be performed either in the lab or in the field in hazardous industrial environments in real-time. Remot...

BACKGROUND Activated platelets can be found on the surface of inflamed, rupture-prone and ruptured plaques as well as in intravascular thrombosis. They are key players in thrombosis and atherosclerosis. In this study we describe the construction of a radiolabeled single-chain antibody targeting the LIBS-epitope of activated platelets to selectively depict platelet activation and wall-adherent n...

Laser-induced breakdown spectroscopy (LIBS) was applied to perform a rapid elemental analysis and provenance study of Blumea balsamifera DC. Principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were implemented to exploit the multivariate nature of the LIBS data. Scores and loadings of computed principal components visually illustrated the differing spectr...
