The desired device pattern is transferred to a photoresist on a substrate using photolithography; at least two coats of polymer are spin-coated onto the substrate to form a polymer layer, a plurality of polystyrene particles of a desired shape and size are drop-coated on the polymer layer, a nanomeric layer of gold is deposited thereover, the polystyrene particles are removed, the hole-mask is etched, a plasmonic metal is deposited into the holes, and the polymer layer and photoresist are then removed prior to optionally sealing with a cover."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Patterned plasmonic nanoparticle arrays for multiplexed, microfluidic biosensing assays","description":"Methods for fabricating a localized surface plasmon renosance (LSPR) biosensing microfluidic or spot-plate device that combines the techniques photolithography and hole-mask colloidal lithography in a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11280784","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.
