A Rolling Circle-Amplified G‑Quadruplex/Hemin DNAzyme for Chemiluminescence Immunoassay of the SARS-CoV‑2 Protein

Sensitive detection of the SARS-CoV-2 protein remains a great research interest in clinical screening and diagnosis owing to the coronavirus epidemic. Here, an ultrasensitive chemiluminescence (CL) imaging strategy was developed through proximity hybridization to trigger the formation of a rolling c...
