Summary: In this study, a strategy (MPT-Cas12a/13a) was developed that combines CRISPR/Cas12a and Cas13a for simultaneous detection of CaMV35S and T-nos. This strategy utilizes multiplex PCR and transcription to achieve simultaneous detection with different signals in the same space. The MPT-Cas12a/13a showed excellent sensitivity, with detection limits as low as 11 copies of T-nos and 13 copies of CaMV35S, and demonstrated outstanding specificity and anti-interference ability in actual sample analysis. Therefore, it has the potential to be used for the detection of GM crops.

Summary: Developing assays that combine CRISPR/Cas and isothermal nucleic acid amplification is a growing research area, with potential for point-of-care applications. Current research mainly focuses on appending different CRISPR/Cas effectors to isothermal nucleic acid amplification methods, but few studies have integrated both components into single-step assays. We conducted a systematic investigation and found that adding CRISPR/Cas12a enhances signal amplification but hinders recombinase polymerase amplification (RPA). We developed a PAM-free CRISPR/Cas12a-assisted RPA assay that outperforms other assays in design, signal, sensitivity, and speed. Our study provides new insights and can facilitate further advances in CRISPR/Cas-based assays.

Summary: Electrochemical biosensors have the potential to be cost-effective diagnostic tools for point-of-care testing. However, the sensitivity of directly analyzing complex biological fluids such as plasma has been limited due to biofouling. This study demonstrates a method for creating nanostructured and nanoporous gold electrodes, which greatly increases the surface area and improves detection sensitivity. The surfactant-based electrochemical etch-deposit interplay for nanostructure/nanopore growth (SEEDING) process enhances the sensitivity and antibiofouling capabilities of biosensors, enabling direct analysis of tumor-derived extracellular vesicles in complex biofluids.
