Centrifugal Field Flow Fractionation hyphenated with Raman Microspectroscopy: Size-resolved Chemical Analysis of Nanoplastics About the lecture The comprehensive physicochemical analysis of nanoplastics is of increasing importance to environmental scientists and toxicologists. Especially centrifugal field flow fractionation facilitates the analysis of complex mixtures and polydisperse samples due to its higher resolution compared to asymmetrical flow field flow fractionation. Chemical information is gained by vibrational (Raman) fingerprint spectra. A flow cell is used for the hyphenation which is enabled by single-beam optical trapping with the laser used for Raman spectroscopic analysis. Overall, hyphenation of field flow fractionation and Raman microspectroscopy allows for size-resolved chemical identification of mineral and plastic particles in the size range of 100 – 5000 nm. About the speaker M. Huber is a PhD student at the Institute of Water Chemistry at the Technical University of Munich in the Raman and SEM group headed by PD Dr. Natalia P. Ivleva. His research is focused on method development for nanoplastic analysis via field flow fractionation incl. combination with various detectors such as multi-angle light scattering, UV and Raman microspectroscopy. |

Detection, characterization and model studies of nanoplastic particles About the lecture This talk will focus on nanoplastics; plastic particles smaller than 1µm in size. First, it will be addressed where they come from, and how we detect them in varying complex matrices. Then, micro-spectroscopic and mass-based techniques will be presented that can characterize small amounts and/or numbers of nanoplastics with large accuracy. Finally, some examples are shown of model studies on nanoplastics, and how they might behave towards organisms and/or human cells. About the speaker Laurens Mandemaker is a researcher at Utrecht University, both in the Institute of Sustainable and Circular Chemistry, and in the Institute for Risk Assessment Sciences, focusing on micro- and nanoplastics. Laurens did his PhD research in the group of Bert Weckhuysen, focusing on developing micro-spectroscopic techniques, such as AFM-IR, IR microscopy but also ToF-SIMS to catalytic thin film model systems. As a Postdoc, he applied this toolbox of techniques to the detection and characterization of nanoplastics. Since then, Laurens has been involved in several large European research initiatives to understand micro- and nanoplastics and their potential risk on (human) health and the environment. |

Developing concepts for safe circular urban food systems About the lecture Large cities in the Netherlands have a big challenge. By 2030, nutrient losses from the agrifood system (-50%), and the use of fertilizers in agrifood production (-20%) must be reduced [1] while Member States must recycle or prepare at least 60% of their municipal waste for reuse [2]. However, biowastes may be contaminated with human pathogens, and in a full circular agrifood system persistent organic and/or inorganic chemical contaminants may accumulate in soil or food. Therefore, we aim to:

Surface Protein Immunocoupling using Ramp Imaging Technology About the lecture Technologies for personalized and cost-effective diagnostic of infectious diseases can greatly enhance our quality of life. Here, a crucial aspect is the rapid and accurate quantification of biomolecular interactions (for example between proteins, viruses), for which Surface Plasmon Resonance imaging (SPRi) is a promising diagnostic tool. SPRi is a label-free, photonic-based technique carried out on biofunctionalized surfaces, used for investigation of biomolecular interactions. It generates thousands of datapoints because every camera pixel corresponds to an individual SPR sensor, while each datapoint generates a sensorgram that could be potentially used for highthroughput diagnostics. During the COVID-19 pandemic, researchers at UT and Interfluidics applied SPRi for realtime and label-free antibody screening of patients, measuring thousands of serum samples. It was found that a patient who will develop severe COVID-19 possesses high antibody concentrations in combination with overall worse quality of the antibodies (weak binding strength). However, such accurate measurements required a high level of expertise and time to extract and analyze the generated data, which hampers widespread use of this technology. To advance SPRi towards high-throughput and point-of-care applications, while decreasing analysis costs and facilitating its adoption in the clinics, novel functional materials and efficient analysis methods for SPRi are urgently needed. In SPIRIT, a new SPRi biosensing method will be developed towards dual measurement of concentration and binding strength of biomolecular interactions. We will i) develop protocols for smart coatings of SPRi substrates, ii) develop protocols for efficient data analysis, and iii) validate the method for diagnostics using a COVID-19 cohort. If successful, SPRi measurements will become “plugand- play”, paving the way for more accessible solutions for personalized diagnostics. |

About the lecture Within the NWA-ORC project OBSeRVeD, a broad consortium is working towards a cheap, low-power and smart very sensitive VOC sensor platform, based on micro- or nanotechnology for making it sufficiently sensitive and scalable, coated with affinity layers.
About the speaker Cas Damen obtained his PhD from the University of Twente under the supervision of Dave Blank and Horst Rogalla in the field of High-Temperature superconductors. Damen is co-founder of Twente Solid State Technology BV, a company specialized in thin layer deposition equipment and currently part of Demcon Holding. Since 1 March 2014, Cas Damen has been appointed professor in Applied Nanotechnology at Saxion University of Applied Sciences in Enschede. Within his research group, research is being conducted into the implementation of chip technology (with a focus on photonic sensor devices) for medical, environmental and food safety applications. |
