Highlight 1. We developed a new DLS immunosensing technology for the rapid and sensitive detection of glycoprotein NT-proBNP. 2. The boronate affinity recognition amplified nanoparticle aggregation was designed to enable highly sensitive DLS transduction. 3. The fabricated DLS immunosensor exhibited ultrahigh sensitivity with an LOD of 7.4 fg mL−1, fast response time (< 20 min), and small sample consumption (1 μL). 4. This boronate affinity amplified-DLS immunosensor has broad prospects for field or point-of-care testing of cis-diol-containing molecules.
