Biosensing platform for immunoreactions: An electrochemical high-throughput sensing platform for simple, sensitive detection of prostate-specific serum antigen (PSA) based on quantum dot (QD) labels is demonstrated (see figure). The high sensitivity stems from the dual signal amplification via QD labels and preconcentration, allowing for detection of extremely low concentrations while using small sample volumes.
