An Ultrasensitive Single-Particle Collision Electrochemical Immunoassay at Subfemtogram-per-Milliliter Levels via Cascaded Hybridization Chain Reaction Amplification
{{output}}
Herein, we developed an ultrasensitive single-particle collision-based electrochemical immunosensing platform for detecting a total prostate-specific antigen (tPSA) as a model target. It relies on the collision events resulting from the enzyme-catalyzed, in si... ...
