This infographic gives researchers and assay developers a practical guide to selecting the right membrane for their lateral flow test (LFT)—so you can optimize sensitivity, speed, and signal clarity at every stage of development.
What you will learn about:
-
- How LFTs work: How sample migration, capillary action, and antibody binding come together to deliver a rapid result
- The membrane variables that matter: Capillary flow rate, surface quality, and polymer composition—and how each drives assay performance
- Sample type = membrane selection: A decision framework matching water, serum, saliva, whole blood, and urine to the right membrane grade (HF075–HF180)
- Application-specific optimization: Real-world examples across COVID-19, cardiac markers, food safety, environmental monitoring, and more
- Complete system optimization: How membranes, conjugate particles, pad materials, and capture antibodies work together for peak assay performance

Lateral flow tests depend on more than antibody selection—the membrane is where chemistry meets performance. This infographic, produced in partnership with Merck, walks diagnostic developers through membrane selection for lateral flow assays: how capillary flow time (CFT) affects sensitivity and speed, why nitrocellulose composition matters for protein binding, and how surface quality affects line sharpness. A decision framework maps five common sample types to recommended membrane grades, with mini case studies spanning pregnancy testing, cardiac markers, food safety, and environmental monitoring.
