摘要
An ultrasensitive DNAzyme-based colorimetric DNA detection strategy was developed by utilizing gold nanoparticles modified with both peroxidase-mimicking DNAzymes and capture DNAs and magnetic nanoparticles modified with another capture DNAs, with a detection limit for a model Chlamydia gene of 50 fM.
