Point-of-Care Pathogen Detection with CRISPR-based Programmable Nucleic Acid Binding Proteins.

The contemporary discovery of extremely versatile engineered nucleic acid-binding proteins has transformed a brave new world in the genome-editing scientific area. Clustered regularly interspaced short palindromic repeats (CRISPR)-mediated programmable nucleic acid-binding proteins have brought about a revolution in diagnostic platforms. The groundbreaking finding that bacteria and archaea that harbored prokaryotes have transmitted adaptive immunity through CRISPR and CRISPR-associated (Cas) proteins has driven revolutionary advances in molecular biology. Importantly, advances in gene editing focus how expanding visions in CRISPR-Cas biology are revolutionizing the area of molecular diagnostics for identifying DNA and RNA in emerging microbiological pathogens, for single nucleotide polymorphism (SNP) identifications, and for cell-free mutation. Recent advances, such as improvements in multiplexing and quantitative capabilities as well as instrument-free detection of nucleic acids, will potentially leverage the introduction of these novel technologies to detecting bacteria and viruses at the point of care (POC). In this review, we highlight the fundamental features of CRISPR/Cas-based molecular diagnostic technologies and summarize a vision of the next applications for identifying pathogens in POC settings.
