PhD Position – Nanoplastic Detection and Characterization The BioNanomaterials Group at the Adolphe Merkle Institute (https://www.ami.swiss/bionanomaterials/en/), led by Prof. Alke Fink and Prof. Barbara Rothen-Rutishauser, is seeking applications for a PhD Position in Nanoplastic Detection and Characterization. Detecting nanoplastics in biological fluids at relevant concentrations (μg/L to ng/L) remains a challenge due to limitations in current analytical techniques. Therefore, there is a need to develop new or modify existing technologies to detect nanoplastics (defined as plastic particles below 1 μm) in biological fluids. The PhD candidate will be tasked with developing analytical strategies to detect and characterize nanoplastics in cell culture media, blood, serum, or plasma. Applicants must hold a master’s degree in chemistry, environmental sciences, or materials science, and have a desire to work within an interdisciplinary research group on a challenging project. Proficiency in well-established nanotechniques (such as dynamic light scattering, nanoparticle tracking analysis, UV-Vis-NIR spectroscopy, Raman, or electron microscopy) and critical thinking skills are essential requirements for the position. Additionally, candidates should possess the ability to work independently as part of a team, excellent communication skills, proficiency in English, and resilience. Previous experience in synthesizing plasmonic nanoparticles is desirable. The Adolphe Merkle Institute offers very attractive employment conditions and provides an outstanding infrastructure within a new research facility. The selected candidate is expected to start in July 2024. Please submit your CV, motivation letter, and contact information for at least two references as a single PDF file via email to ami.applications@unifr.ch with the subject title “ PhD Position – Nanoplastic Detection ”.

Two PhD Positions - Soft Matter Physics Group The Adolphe Merkle Institute's Soft Matter Physics Group (Prof. Ullrich Steiner) invites applications for two PhD positions in the "Strong Localisation of Light through the Controlled Assembly of Amorphous Patchy Colloid Networks” project. In opaque materials, light is multiply scattered before emerging. A long-standing interesting fundamental question arises: I s it possible to design a strongly scattering material from which light never emerges? While theoretically predicted and despite several experimental efforts, this effect has not yet been demonstrated. Our approach follows the theoretical studies, which require an interplay of order and disorder in the arrangement of the scatterers within the material. To this end, we will develop a system of colloidal building blocks that can be assembled into networks, allowing us to adjust the order-disorder interplay of the resulting network. These 3D networks are then replicated into high-refractive index materials (silicon or titania) and optically characterised to achieve strong light scattering. One of the PhD projects concerns the creation of the building blocks, i.e., the synthesis of the colloids and their assembly, while the second will work on replicating the networks as mentioned above. Both students will also use molecular dynamics and optical simulations to predict promising network morphologies, guiding their experiments. Applicants must have a Master’s degree in Chemistry, Materials Science, or Physics and wish to pursue interdisciplinary research in a fast-moving international team. The ability to advance a complex project independently and as part of a team, excellent communication skills, and proficiency in English are key requirements for this position. Experience in polymer or colloid science will be of advantage, and some knowledge of optics is desirable. The Adolphe Merkle Institute offers attractive employment conditions and outstanding infrastructure in a new research facility.The position will be filled as soon as possible. Please send your CV, motivation letter, and contact information of at least two references as one PDF file via E‐mail to ami.applications@unifr.ch with the subject title “PhD Light Localisation”.
