title: One-step colorimetric detection of an antibody based on protein-induced unfolding of a G-quadruplex switch.
abstract: A simple colorimetric assay is developed for the sensitive and selective detection of an antibody, which combines a protein binding-induced signaling approach with a novel DNAzyme-based conformational switching strategy.
