By rationally employing enzymes for signal amplification, an ultrasensitive aptasensor was developed and successfully tested in a system designed to detect lysozyme with a detection limit of 0.1 fM. This detection limit is nearly three orders of magnitude lower than those of any previously reported DNAzyme-based aptasensors.
