Physicochemical Characterisation of the E171 Food Additive
sample preparation protocols influencing particle dispersion (pH, probe sonication and centrifugation) were tested and optimized. In optimized conditions, representative TEM micrographs could be recorded, ...
Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids
issue, a proper sample preparation is needed, to improve the life span of the column and reduce the total number of cuts in the GC-column. The aim of our study is to quantify potential harmful flavourings ...
Evaluation of a TEM based Approach for Size Measurement of Particulate (Nano)materials
specimen preparation, imaging, and image analysis, and it was evaluated on a series of certified reference materials and representative test materials with varying physical properties, including particle ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
“nano” labeling poses several analytical challenges. This includes the many potential sources of NP s in food which can interfere with the analysis, the challenges in relation to sample preparation, the ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- MS / MS using ...
Falsification of biotechnology drugs: current dangers and/or future disasters?
falsified. The danger regarding the use of these falsified polypeptide drugs lies in the fact that end-users have no guarantee of the safety and efficacy of these preparations. Multiple reports have namely ...
Preparing cDNA Libraries from Lytic Phage-Infected Cells for Whole Transcriptome Analysis by RNA-Seq.
Publication Type: Peer reviewed scientific article Authors: Blasdel, Bob; Pieter-Jan Ceyssens; Lavigne, Rob Source: Methods Mol Biol, Volume 1681, Issue 1681, Number 1941 (2018) Keywords: Bacteriophage RNA-seq Abstract: Whole genome wide analysis of trans ...
Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?
concentration. The number-based size distribution of Ag particles was verified by transmission electron microscopy. Sample preparation, which included separation of the particles from the matrix in case of food ...
Very Long Persistence of Botulinum Toxin B in a Patient’s Serum
of BoNT B in the serum and ii) the risks related to the preparation of artisanal products as well as the importance of an efficient communication to citizens regarding preservation methods of ...
Convenient one-pot formation of highly functionalized 5-bromo-2-aminothiazoles, potential endocannabinoid hydrolase MAGL inhibitors
Abstract: Highly functionalized 5-bromo-2-amino-1,3-thiazoles bearing various substituents could be easily prepared by a rapid and efficient one-pot method, using simple starting materials and mild conditions ...
