Open Lab Application for the Characterization of Nanomaterials by Transmission Electron Microscopy

expertise and instrumentation to measure the size, morphology, crystallographic structure and chemical composition of a wide range of NM by EM. Identification and measurement of particles can be performed in ...

Multivalent binding of herpesvirus to living cells is tightly regulated during infection.

8 (2018) Abstract: Viral infection, initiated by the landing of a virion on a cellular surface, is largely defined by the preliminary interactions established between viral particles and their receptors at ...

Y-box-binding protein 1 supports the early and late steps of HIV replication.

the cellular YB-1 levels. More precisely, using quantitative PCR and an in vivo nuclear import assay with fluorescently labeled viral particles, we showed that YB-1 knockdown leads to a block between ...

Screening for nanoparticles in complex matrices within a regulatory framework: are we there yet?

samples of E174 and ten food items containing E174 were investigated for their number-based size distribution of Ag particles. The food items were as well investigated for their total Ag content. Single ...

Characterization of the nano-sized fraction of particles in food additives E174, E175 and E171

Publication Type: Scientific poster, presentation or proceeding Authors: Eveline Verleysen Source: 2nd nano in Belgium workshop, the Belgian EU-OSHA Focal point, Brussels, Belgium (2018) Keywords: Food Additives nanomaterials Abstract: presentation at the ...

Improved Metrological Traceability of Particle Size Values Measured with Line-Start Incremental Centrifugal Liquid Sedimentation.

Volume 33, Issue 33, p.8213-8224 (2017) Abstract: Line-start incremental centrifugal liquid sedimentation (disc- CLS) is a powerful method to determine particle size based on the principles of Stokes’ law. ...

Validation of a particle tracking analysis method for the size determination of nano- and microparticles.

p.271 (2017) Abstract: Particle tracking analysis (PTA) is an emerging technique suitable for size analysis of particles with external dimensions in the nano- and sub-micrometre scale range. Only limited ...

Human absorption of silver ENM: through particles or ions?

the administered dose was excreted via urine and feces. This demonstrates that NM-300K, once present systemically, is circulated as particles and solubilization is limited. After treatment of the ...

Chromatographic fingerprinting as a strategy to identify regulated plants in illegal herbal supplements.

Tribulus terrestris. The full factorial design demonstrated that for all three plant references a C8 column (250mm×4.6mm; 5µm particle size) is best suited; methanol and an ammonium formate buffer (pH 3) ...

Replication-Deficient Particles: New Insights into the Next Generation of Bluetongue Virus Vaccines.

Publication Type: Peer reviewed scientific article Authors: Celma, Cristina C; Stewart, Meredith; Wernike, Kerstin; Eschbaumer, Michael; Gonzalez-Molleda, Lorenzo; Bréard, Emmanuel; Schulz, Claudia; Hoffmann, Bernd; Andy Haegeman; Kris De Clercq; Zientara ...
