The projections have a height, cross-section and a distance between one another that defines a capillary space between the projections capable of generating capillary flow parallel to the substrate surface; and a sink in fluid communication with the capture zone having a capacity to receive liquid sample flowing from the capture zone. The sample receiving zone, the capture zone and the sink define a fluid flow path. Preferably, the rhombus-shaped cross-section is a square or a diamond."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Assay device having rhombus-shaped projections","description":"An assay device includes: a liquid sample receiving zone; a capture zone in fluid communication with the sample receiving zone having capture elements bound thereto, the capture zone having a substrat","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9651489","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
