According to the invention there is a further such sensor 9, of substantially identical form but having its sensor structure 14 already conjugated with the biomarker, or otherwise capped, e.g. using a further oligonucleotide strand, so as to act as an internal reference. When a biological sample, e.g. saliva, is applied to the electrodes, the reference enables the discounting of all environmental effects other than the biomarker. The invention provides a simple, cheap and accurate text for one or more biomarkers that can be used in the field without complex equipment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Aptamer coated measurement and reference electrodes and methods using same for biomarker detection","description":"A device for identifying the presence of a specific target molecule or biomarker by the detection of a change in an electrical property includes a measurement sensor 8 comprising a semiconducting sens","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9753031","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.
