Abstract

A label-free and enzyme-free colorimetric sensing platform for the amplified detection of fibronectin was developed based on an ingenious combination of catalytic hairpin assembly and a base stacking hybridization-based gold nanoparticle aggregation strategy. The detection limit of 2.3 pM is at least one order of magnitude lower than that of established fibronectin biosensors.
