Oliver Germershaus
Professor for Pharmaceutical Technology of Macromolecular Drugs
Oliver Germershaus is Professor of Pharmaceutics of Macromolecular Drugs and Head of the Institute of Pharmaceutical Technology and Biotechnology at the University of Applied Sciences Northwestern Switzerland. His research focus areas include formulation and processing of biologics, development of drug delivery systems, and parenteral packaging and device development. In recent years, he has placed special emphasis on developing novel particle standards designed to match the appearance and behavior of inherent particles.
Germershaus is co-founder and chief scientific officer of Partiris, a Swiss startup that focuses on developing and manufacturing specialized pharmaceutical standard materials, such as particle standards for manual and automatic visual inspection.
DAY 2: September 29th, 2026
SESSION: Precision-Designed 3D Printed Inherent Particle Mimics for Visual Inspection System Qualification
◆ Conventional standards (polystyrene spheres, glass beads) poorly represent real parenteral particles in refractive index, morphology, and suspension behavior.
◆ Two-photon 3D printing enables precise tuning of particle size, shape, and optical properties to create more realistic standards.
◆ Standards can be tailored to mimic product-specific particles such as protein aggregates or cell clumps.
◆ Case study 1: protein-like model particles developed to qualify automated visual inspection instruments.
◆ Case study 2: cell clump mimics and suspension surrogates designed for cell therapy product inspection.
◆ Probability-of-detection studies were performed across varying particle sizes and matrices.
