Detection of SARS-cov-2 using the Crisper/Cas system. (1) The Crisper/Cas9 system binds to specific sequences using gRNA. (2) If we remove the cutting effect from this system and (3) add a fluorescent dye, we can bind it to the desired sequences. When it is bound to the desired sequence, it will produce a green color. (4) With this ability of the CRISPR/CAS9 system, many SARS-CoV-2 samples can be detected in a short time.
