title: Aptamer-tagged DNA origami for spatially addressable detection of aflatoxin B1.
abstract: A DNA origami-based platform for detecting aflatoxin B1 has been constructed with the assistance of aptamer probes and its complementary ssDNA-modified gold nanoparticles. This work may open new horizons for the application of DNA origami in the detection of a variety of small molecules.
