| 摘要 |
The invention provides methods and compositions for detecting binding or unbinding of a molecule to a substrate. The molecule comprises a luminophore and the substrate comprises a semiconductor which acts as a luminescence quencher to provide distance-dependent quenching of the luminophore. Binding or unbinding of the molecule, which may be covalent or noncovalent, is detected as a decrease or increase, respectively, of the detectable luminescence of the luminophore.
