Lattice-like 3-dimensional DNA nanostructure-based bioseparation strategy for highly accurate quantification of low-abundance cancer biomarker via mass spectrometry
Chemical Engineering Journal(2022)
Abstract
•A 3-dimensional DNA tetrahedron carrier was used for precise antibody arrangement.•The composites exhibited ideal performance in the capture of low-abundance HSP90α.•The novel strategy has great potential in quantification of other protein biomarkers.
