Establishment and optimization of a system for the detection of Candida albicans based on enzymatic recombinase amplification and CRISPR/Cas12a system

Abstract

This study established a two-step method through optimization, compared its sensitivity, and then combined the specific detection capabilities of ERA and CRISPR/Cas12a. Furthermore, a one-step method was developed based on the two-step method, creating a one-step system for the detection of Candida albicans . This system does not require the lid to be opened during the reaction process, reducing aerosol contamination and minimizing the risk of false positives. This method does not require advanced instruments or equipment and shows strong specificity without being affected by other pathogens. It can serve as a new method for the detection of Candida albicans and has significant practical application prospects.
