The cell channels (20) comprise a respective obstruction (25) designed to prevent the target cells from passing the respective obstruction (25) and into the flow output channel (40). The microfluidic device (1) also comprises a pre-filter (50) with a filter channel (60) in fluid connection with a first filter port (61) and pre-filter channels (70) adapted to accommodate the target cells. A respective first end (72) of the pre-filter channels (70) is in fluid connection with the filter channel (60) and a respective second end (74) of the pre-filter channels (70) is in fluid connection with the flow input channel (30)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Microfluidic device","description":"A microfluidic device (1) comprises a substrate (10) having a flow input channel (30) in fluid connection with a first fluid port (31) and a flow output channel (40) in fluid connection with a third f","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11946029","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.
