With the increasing use of nanotechnology in food and consumer products, there is a need for reliable detection and characterization methods for nanoparticles (NPs) in complex matrices. NPs often interact with each other or with their surroundings leading to aggregation, adhesion to surfaces or dissolution in dispersion solvents. Accurate and precise characterization of metrics such as size, shape, particle mass and number concentration therefore remains a challenging analytical task. Asymmetric flow field flow fractionation (AF4) hyphenated with inductively coupled plasma mass spectrometry (ICP-MS) is a powerful technique for the detection and characterization of inorganic NPs in complex matrices. In order to acquire accurate data the AF4 separation method and settings must be optimized for each new sample matrix and analyte NP combination. Furthermore, additional information obtained by single particle (sp) ICP-MS analysis of collected fractions or an imaging method such as transmission electron microscopy (TEM) are necessary for trouble shooting and for independent verification of results. spICP-MS as stand-alone technique is a powerful screening method for many inorganic NPs. A number of examples where AF4-ICP-MS and single particle ICP-MS were applied for the detection and characterization of NPs in food and biological matrices will be presented including: • Silver NPs in chicken meat • Silicon dioxide NPs in tomato soup • Aluminum-containing NPs in noodles • Gold NPs in cells

In this webinar, Dr Robert Williams, Chief Development Scientist, Cancer Research UK, will discuss how partnership between academia and industry can accelerate drug development.

In this presentation we will explore the opportunities afforded by the hybrid magneto-plasmonic nanoparticles and PA imaging for the development of a low cost simple and nearly real-time assays for capture, separation and enumeration of rare cells.

Peter Ertl discusses how for the first time, direct cell-to-cell interactions of tumor cells with bead-activated primary T cells were continuously assessed using an effector cell to target cell ratio of 10:1.

In this talk, Mark Cragg, presents evidence that different mAb's interact with Fc receptors differently in order to achieve their therapeutic activities.
