The building blocks self-assemble fully reversibly from complementary single-stranded DNA segments. We compare melting curves from both simulations with the oxDNA2 model and experiments and find excellent agreement. The morphology of the Y-DNA molecules is investigated when several alterations in the design are made. Adding inert nucleotides to the central core region of the Y-DNA molecules has a very minor effect on their overall geometry, whereas palindromic sequences in the sticky ends vi","authors_text":"Erika Eiser, Magdalena Hudek, Oliver Henrich, Yair Augusto Gutierrez Fosado, Zhongyang Xing","cross_cats":["cond-mat.mtrl-sci","physics.bio-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2019-03-11T09:31:02Z","title":"A Numerical Study of Three-Armed DNA Hydrogel Structures"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.04186","kind":"arxiv","version":2},"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":"sha256:31d4ec30ef8d668c2601d557ce11baf6f4ff33eecda3c7c406e9f5d6dc99808b","target":"record","created_at":"2026-05-17T23:49:32Z","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":"777fad1057501423619b6735a242f612e21950d3879d88b7874f702e3e64d484","cross_cats_sorted":["cond-mat.mtrl-sci","physics.bio-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2019-03-11T09:31:02Z","title_canon_sha256":"8de3d05541b4b4ab0e16dc9e6272d41d8b047a59fa5fc5ef0223a6e4ae49f16c"},"schema_version":"1.0","source":{"id":"1903.04186","kind":"arxiv","version":2}},"canonical_sha256":"ca7e20f395f47c9dee4d6642c92620dca909c4d437f1d7f7e099e48fdc25aed7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ca7e20f395f47c9dee4d6642c92620dca909c4d437f1d7f7e099e48fdc25aed7","first_computed_at":"2026-05-17T23:49:32.735378Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:49:32.735378Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"I/MJy0th4KoOU8HlqbHuwl9sYeMoZIWKeHDp5J6uatCb1LFio1zFJT10V2E2CzQ+kFmDTk6lKiI0CUGXSXcvBg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:49:32.735855Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.04186","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:31d4ec30ef8d668c2601d557ce11baf6f4ff33eecda3c7c406e9f5d6dc99808b","sha256:07f72299c43e49b679722c8a2bd4c4120a043dc65ae8812afe5a6aecc599af1a"],"state_sha256":"46a85997c261ac47e00799f2b7dbdae78b0b09b11e6d4ed7f3c684e83fba1522"}
