Validation of a multi-residue method to determine deltamethrin and alpha-cypermethrin in mosquito nets by gas chromatography with electron capture detection (GC-µECD) [PDF]

, 2013
Background: Nowadays long-lasting insecticidal mosquito nets (LNs) are frequently used around the world to protect people against malaria vectors. As they contain insecticide, laboratory control is needed to check whether the content of the active ...

Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection

Angewandte Chemie, EarlyView.
In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...

Human Mycotoxin Biomonitoring: Conclusive remarks on direct or indirect assessment of urinary deoxynivalenol [PDF]

, 2020
Deoxynivalenol is one of the most ubiquitous mycotoxins in the Western diet through its presence in cereals and cereal products. A vast amount of studies indicate the worrying level of exposure to this toxin, while even high percentages of the population

Analytical method validation: A brief review

World Journal of Advanced Research and Reviews, 2022
Validation is an applied approach to verify that a method is suitable to function as a quality control tool. The objective of any analytical measurement is to obtain consistent, reliable and accurate data.

Simultaneous quantification of 12 different nucleotides and nucleosides released from renal epithelium and in human urine samples using ion-pair reversed-phase HPLC [PDF]

, 2012
Nucleotides and nucleosides are not only involved in cellular metabolism but also act extracellularly via P1 and P2 receptors, to elicit a wide variety of physiological and pathophysiological responses through paracrine and autocrine signalling pathways.

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture

Advanced Healthcare Materials, EarlyView.
This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Development and validation of a sensitive liquid chromatography-tandem mass spectrometry method for the analysis of Mancozeb residues in cauliflower: Risk assessment of real samples

Journal of Chromatography Open
The Dithiocarbamate (DTC) group represents one of the largest consumed fungicides. Presently the most extensively used UV–Visible spectrophotometric method for quantification of DTCs suffers from a lack of sensitivity for trace level detection of residue,

The entanglement of purification [PDF]

, 2002
We introduce a measure of both quantum as well as classical correlations in a quantum state, the entanglement of purification. We show that the (regularized) entanglement of purification is equal to the entanglement cost of creating a state $\rho ...
