Preservation of Extracellular Vesicle Integrity and Cargo Using Spiral Microfluidic Chip‐Based Separation

Advanced Materials Technologies, EarlyView.
A spiral microfluidic chip is compared with ultrafiltration for the separation of extracellular vesicles (EVs). The method preserves miRNA cargo and membrane integrity more effectively, resulting in intact vesicle morphology and consistent surface biomarker expression.

Cap‐oPMN: Oral Inflammatory Load Quantification Using Capillary Microfluidics and Automated Image Processing

Advanced Materials Technologies, EarlyView.
ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...
