Abstract Here we report on the development of a CRISPR-based assay for sensitive and specific detection antibodies antigens directly in complex sample matrices. The assay, called Molecular Assay based antibody-Induced Guide-RNA Enzymatic Transcription (MAIGRET), is use responsive synthetic DNA template that triggers cell-free vitro transcription guide RNA strand upon recognition target antibody. Such transcribed activates collateral activity Cas12a enzyme, leading to downstream cleavage fluorophore/quencher-labeled reporter thus resulting an increase measured fluorescence signal. We have used MAIGRET six different with high sensitivity (detection limit picomolar range) specificity (no signal presence non-target antibodies). can also be adapted competitive approach antigens. With MAIGRET, significantly expand scope applicability sensing approaches potentially enable measurement any molecular which antibody available.

The absence of sensitive, multiplexed, and point-of-care assays poses a critical obstacle in promptly responding to emerging human respiratory virus (HRV) pandemics. Herein, RECOGNIZER (re-building commercial pregnancy strips via large-size nanoflowers), an innovative one-pot CRISPR assay, is presented that employs commercially available identify several types HRVs. superiority the assay mainly relies on two aspects: (i) DNA nanoflowers possessing high surface-to-volume ratio well-defined surface allow for considerable probe loading density minimized non-specific interaction, achieving impressive signal-to-noise proportion exceeding tenfold at 1 nM target. (ii) design reaction, multi-channel chip, custom-made app enables rapid, sample-to-answer, multiplexed analysis four HRVs 25 min. This demonstrates sensitivity 5.42 pM synthetic SARS-CoV-2 RNA 10 copies µL-1 plasmids after pre-amplification. Finally, proposed approach indicated 100% accuracy 50 clinical swab samples, demonstrating robust performance distinguishing from other versatility scalability renders it user-friendly platform infection monitoring, offering significant potential improving pandemic response efforts.
