Here, we review a broad range of traditional and novel techniques that have been utilized for developing advanced biosensing tools including colloidal nanoparticles (NPs)-based systems to well-engineered arrays of meta-atoms and metamolecules. By describing some of the important and practical label-free biosensing methods based on subwavelength plasmonic technology, we discuss the emerg","authors_text":"Arash Ahmadivand, Burak Gerislioglu","cross_cats":["physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2018-09-13T12:48:24Z","title":"Toroidal Plasmonic Meta-Biosensors: Benchmarking against Classical Plasmonic Biosensors and Transducers"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1809.05602","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5b240459bd771eb66cde9f2a6d790b2866812bc404675d53fd65eccf80b8f59d","target":"record","created_at":"2026-05-18T00:05:40Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"a85d572b80af40f8161da0e2506b66eb0bceeb065347529b86fc1847ea2d2861","cross_cats_sorted":["physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2018-09-13T12:48:24Z","title_canon_sha256":"fbe005768f582bd9782a4faf38728dde64c45e7caec6c61bbab4f3be210a043e"},"schema_version":"1.0","source":{"id":"1809.05602","kind":"arxiv","version":1}},"canonical_sha256":"36b4a94e77e3e16182b527e59e7adc46f7d6053baa8e7456652bcc12e3ecbef6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"36b4a94e77e3e16182b527e59e7adc46f7d6053baa8e7456652bcc12e3ecbef6","first_computed_at":"2026-05-18T00:05:40.556074Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:05:40.556074Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"TfgRdf3DDI7mNkHIpojbWbg8Ufgzz+b9M67NscJb05AxKL0mj+CzfdS07/piIVmH38c5NIw32XNeASQLLgSNCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:05:40.556685Z","signed_message":"canonical_sha256_bytes"},"source_id":"1809.05602","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5b240459bd771eb66cde9f2a6d790b2866812bc404675d53fd65eccf80b8f59d","sha256:c340128afc27b4325d7246e67ee8cab0eb89cf2ee4736954e5a46f51dbba97df"],"state_sha256":"ffb2073e7e8983c621473dd0bcb0cd9d2bc66b331a714784c6b378c37d9767cd"}
