| Outline of Final Research Achievements |
In this research, we have attempted to develop a DNA nano-tweezers structured (DNA-NT) biosensing molecule for the detection of a desired target in a homogeneous assay format that does not require washing steps.
As a results, we have continuously detected a specific mRNA in living cells with a fluorescence-based DNA-NT biosensing molecule in a homogeneous assay format, we have proved a basic concept to create a new DNA-NT biosensing molecule that detects a desired target, and we have created a split-DNazyme-based DNA-NT biosensing molecule that exhibits an enzymatic activity in response to target recognition.
