title: Homogeneous bioluminescence detection of biomolecules using target-triggered hybridization chain reaction-mediated ligation without luciferase label.
abstract: We develop a new homogeneous method for sensitive detection of various biomolecules on the basis of bioluminescence monitoring the released AMP from the target-triggered hybridization chain reaction-mediated ligation. The introduction of hybridization chain reaction not only improves the sensitivity of DNA assay, but also facilitates the sensitive detection of proteins by designing specific aptamer triggers, providing a universally amplified platform for simultaneous detection of different kinds of biomolecules. Importantly, this bioluminescence assay employs the target-dependent ATP from the ligation byproduct of AMP as the reporter without the requirement for the sophisticated luciferase manipulation, complicated immobilization, and separation steps. The proposed method has significant advantages of simplicity, high sensitivity, low cost, and high throughput, and holds a great promise for practical point-of-care applications.
