Crispr/Cas-Based In Vitro Diagnostic Platforms For Cancer Biomarker Detection
ANALYTICAL CHEMISTRY(2021)
Abstract
Timely diagnosis is of great benefit to improve the survival rate of cancer patients. Body fluid cancer biomarker detection is a critical kind of noninvasive method for cancer diagnosis. Nevertheless, traditional methods for cancer biomarker detection always rely on a large-scale instrument and involve sophisticated operation. Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas)-based in vitro diagnosis can simplify the detection procedures and improve sensitivity and specificity, holding great promise as the next-generation molecular diagnostic technology. In this Feature, we introduce the working mechanisms of different kinds of CRISPR/Cas systems for biosensing and CRISPR/Cas-mediated detection strategies for different kinds of cancer biomarkers including nucleic acids, proteins, and extracellular vesicles. In addition, the perspective and challenges of CRISPR/Cas-based strategies for cancer biomarkers are discussed.
