We construct a sensitive chemiluminescent biosensor for sensitive detection of cytosine deaminase APOBEC3A based on deamination-triggered exponential signal amplification. This biosensor displays good specificity and high sensitivity, and it can screen APOBEC3A inhibitors and measure endogenous APOBEC3A at the single-cell level, with prospective applications in disease diagnostics and therapy.
