In addition, a nanogap is formed by an ultrasmall void having no limitation in diffusion between metal cores through Van der Waals interaction between the metal core particles, as the etching proceeds. It is possible to enhance a near-field significantly around the nanogap structure."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Nanogap structure having ultrasmall void between metal cores and molecular sensing apparatus and method using the same, and method for preparing the nanogap structure by selective etching","description":"By forming a monolayer of metal core-shell nanoparticles, transferring the monolayer to various substrates and removing the shells surrounding the particles by way of selective etching, it is possible","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10520442","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.
