ClearScreening for subvisible particles in pharmaceutical formulations – a case study
This study applied flow imaging microscopy to detect and characterize subvisible particles in pharmaceutical formulations — a quality control challenge that shares methodological overlap with microplastic detection. Improved particle characterization methods in the pharmaceutical sector can also advance techniques for identifying nanoplastics in biological and environmental samples.
Removal of Microplastics and Performance of a Developed Ceramic Filter
Researchers developed a ceramic filter from clay and waste glass with varying porogenic agent content and firing temperatures, then evaluated water permeability, element leaching, and microplastic removal efficiency. The formulation without a porogenic agent achieved the highest microplastic removal rate of nearly 99.8%, demonstrating that optimizing porosity and filtration pressure is key to effective and affordable microplastic filtration.
Investigations on the Particle Fouling and Backwash Efficiency During Microplastic Microfiltration–Particle Size Aspects
Researchers characterised polystyrene microplastic microfiltration through cellulose acetate membranes, testing particle and pore sizes in comparable ranges to challenge dead-end filtration. Particle size relative to pore size strongly influenced fouling behaviour, and backwashing efficiency varied with particle characteristics, informing filtration system design for MP removal.

A strategy for quantifying microplastic particles in membrane filtration processes using flow cytometry
Researchers demonstrated that flow cytometry can rapidly quantify plastic microbead concentrations (1-5 µm) in water with or without added humic acid, and applied the method to evaluate two microfiltration membranes.
