CRISPR/Cas Multiplexed Biosensing: A Challenge or an Insurmountable Obstacle?

Performing multiplex detection is still an elusive goal for molecular diagnostics. CRISPR/Cas-based biosensing has demonstrated potential for multiplex detection. Instead of being an insurmountable obstacle, CRISPR/Cas multiplexed biosensing is a realistic challenge with some recent successful applications. Strategic considerations are required to fully explore its potential in multiplex diagnostics. Performing multiplex detection is still an elusive goal for molecular diagnostics.

CRISPR/Cas Powered Multiplexed BiosensingBruch et al.Trends in BiotechnologyMay 8, 2019In BriefMultiplexed CRISPR/Cas biosensing offers various possibilities for diagnosing different diseases by analyzing many analytes from one single specimen. However, in this relatively new field, nearly no multiplexing approaches exist, as many challenges need to be addressed. We discuss the reasons behind it and possible strategies to push the multiplexing level.

The recent discovery of the collateral RNA cleavage activity of the Cas13a effector has sparked even greater interest in developing novel biosensing technologies for nucleic acid detection and promised significant advances in CRISPR diagnostics. Now, along with the discovery of Cas12 collateral cleavage activities on single-stranded DNA (ssDNA), several CRISPR/Cas systems have been established for detecting various targets, including bacteria, viruses, cancer mutations, and others.
