Snippet: A practical colorimetric assay was developed for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For this purpose, magnetic γ Fe(2)O(3) nanoparticles were synthesized and used as a peroxidase-like mimic activity molecule. In the presence of γ Fe(2)O(3) nanoparticles, the color change of H(2)O(2) included 3,3′,5,5′-tetramethylbenzidine was monitored at the wavelength of 654 nm when spike protein interacted with angiotensin-converting enzyme 2 receptor.

Document: A practical colorimetric assay was developed for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For this purpose, magnetic γ Fe(2)O(3) nanoparticles were synthesized and used as a peroxidase-like mimic activity molecule. In the presence of γ Fe(2)O(3) nanoparticles, the color change of H(2)O(2) included 3,3′,5,5′-tetramethylbenzidine was monitored at the wavelength of 654 nm when spike protein interacted with angiotensin-converting enzyme 2 receptor. This oxidation-reduction reaction was examined both spectroscopically and by using electrochemical techniques. The experimental parameters were optimized and the analytical characteristics investigated. The developed assay was applied to real SARS-CoV-2 samples, and very good results that were in accordance with the real time polymerase chain reaction were obtained.
