Measuring particle concentration of multimodal synthetic reference materials and extracellular vesicles with orthogonal techniques: Who is up to the challenge?
Vogel, Robert; Savage, John; Muzard, Julien; Camera, Giacomo Della; Vella, Gabriele; Law, Alice; Marchioni, Marianne; Mehn, Dora; Geiss, Otmar; Peacock, Ben; Aubert, Dimitri; Calzolai, Luigi; Caputo, Fanny; Prina-Mello, Adriele (Peer reviewed; Journal article, 2021)The measurement of physicochemical properties of polydisperse complex biological samples, for example, extracellular vesicles, is critical to assess their quality, for example, resulting from their production and isolation ... -
Measuring particle size distribution and mass concentration of nanoplastics and microplastics: addressing some analytical challenges in the sub-micron size range
Caputo, Fanny; Vogel, R.; Savage, J.; Vella, G.; Law, A.; Della Camera, Camera; Hannon, G.; Peacock, B.; Mehn, Dora; Ponti, J.; Geiss, Otmar; Aubert, D.; Prina-Mello, Adriele; Calzolai, Luigi (Peer reviewed; Journal article, 2021)HYPOTHESIS:The implementation of the proposal from the European Chemical Agency (ECHA) to restrict the use of nanoplastics (NP) and microplastics (MP) in consumer products will require reliable methods to perform size and ... -
