Title: Label-free optical sensing and characterization of biomolecules by d8 or d10 metal complexes
Usefulness: Label-free optical sensing and characterization of biomolecules by d8 or d10 metal complexes
Summary: For detecting and characterizing a multiply-charged biomolecule, e.g. single-stranded nucleic acid, protein or polypeptide, in a sample (claimed). Also useful for detecting structural changes of target single-stranded nucleic acid and detecting mutation in a target single-stranded nucleic acid.
Novelty: Composition for detecting charged biomolecule comprises charged metal complex with 8 or 10 electrons in d-orbital, which electrostatically binds to biomolecule to induce aggregation and self-assembly via metal-metal and pi-pi interactions
