Peroxidase-like two-dimensional DNA/Fe3O4 networks were constructed by the hybridization chain reaction and applied to detect microRNA down to the aM level.
Designing antibody-powered DNA nanodevice switches is crucial and fascinating to perform a variety of functions in response to specific antibodies as regulatory inputs, achieving the highly sensitive detection by integrating...
Upon adding THBV, the self-assembly of THBV with H1 allows the rest of the DNA sequence of H1 to accelerate H1–H2 complex formation. The G-quadruplex at the end of the H1–H2 complex could catalyze TMB into a colored product.
A new electrochemical biosensor based on the hybridization chain reaction and layered molybdenum selenide (MoSe2) stacked nanorod for dual-signal amplification is developed for the highly sensitive detection of the DNA sequences of Human Immunodeficiency Virus type 1 (HIV-1).
