Dual-nanogold-linked bio-barcodes with superstructures for in situ amplified electronic detection of low-abundance proteins.
A novel and nonenzyme immunosensing protocol is proposed for ultrahighly sensitive detection of low-abundance-proteins (carcinoembryonic antigen as a model) using dual nanogold-linked complementary bio-barcodes with superstructures for in situ amplified electronic signals.
