👉 The reporter fluid, a key component in DNA-based nanotechnology, is a synthetic polymer that facilitates the detection and visualization of DNA interactions. It acts as a reporter by undergoing a detectable change, such as a color shift or fluorescence emission, when it binds to specific DNA sequences or hybridizes with complementary strands. This property makes reporter fluid invaluable for real-time monitoring of DNA processes, enabling researchers to track and analyze complex molecular interactions with high precision and sensitivity.
