This assay detects telomerase activity in cells, indicating a new approach for cancer diagnostics.
A simple, low-cost, amplification-free and ultrasensitive assay was developed to detect telomerase via telomerase self-extension, exonuclease III cleavage, and peroxidase-like activity of AuNPs with detection limit of ∼0.3 MCF-7 cell.
