Regulatory safety assessment of nanoparticles for the food chain in Europe
small particles (including nanoparticles) in products used in the food chain in the EU falls within the remit of the European Food Safety Authority (EFSA) and has been under thorough scientific ...
Sentinel-2 Satellite and Hysplit Model Show that Local Cereal Harvesting Substantially Contributes to Peak Alternaria Spore Concentrations
contribution of cereal harvesting to peak Alternaria spore concentrations. Daily Alternaria spores were collected using Hirst-type traps in 12 sites in Europe for the period 2016-2018. Hybrid Single-Particle ...
Advances in the physicochemical characterization of nanoparticles in a regulatory context.
specifying, registering and labelling, as well as characterizing particulate (nano)materials for risk assessment, require measurement of the physicochemical properties of their constituent particles. Because of ...
Evaluation of the types, efficient use and health risks of application of silver-based biocides to provide antimicrobial properties to face masks applied during the Covid-19 crisis
distributed in the matrix of the fibers, (iii) Ag NP and large silver particles at the surface of, or close to cotton fibres in face masks containing polycationic polymers binding Ag+ ions, and (iv) a coating ...
Ultrastable Silver Nanoparticles for Rapid Serology Detection of Anti-SARS-CoV-2 Immunoglobulins G.
particles. In real clinical samples, the AgNP-based dipstick assays showed impressive results: 100% specificity was observed for negative samples, while a sensitivity of 73% was determined for positive ...
