Summary: We developed a versatile biosensing platform, SCENT-Cas (Silver nanoCluster Empowered Nucleic acids Test using CRISPR/Cas12a), for ultrasensitive detection of pathogenic bacteria. This platform used the isothermal amplification of the invA gene of Salmonella typhimurium to trigger trans-cleavage of CRISPR/Cas12a. The trans-cleavage was then utilized to degrade single-stranded DNA and create a ratiometric fluorescence biosensing platform. This method enabled the detection of 1 CFU/mL S. typhi with a dynamic range from 1 to 108 CFU/mL, and showed promise for real food sample testing.

Summary: This article reviews recent fabrication methods for surface-enhanced Raman spectroscopy (SERS) substrates, focusing on advanced nanoarchitecture based on noble metals, nanolayered 2D materials, and nanoarchitecturing with organic molecules. The use of SERS has been extensively investigated for its enhanced signal intensity and the ability to detect a very small number of molecules. Nanoarchitecture strategies are crucial in the development of SERS substrates. The article discusses recent achievements in the morphology of metallic nanostructures and outlines future directions for reproducible preparation and well-controlled nanoarchitecture.

Summary: This study demonstrates the chemically enhanced trans-cleavage activity of Cas12a and Cas13a nucleases, leading to improved performance of CRISPR/Cas biosensors. Sulfhydryl reductants and non-ionic surfactants were found effective in enhancing the trans-ssDNA cleavage of Cas12a and trans-ssRNA cleavage of Cas13a, respectively. The mechanism of enhancement was identified to be a conformational change of the ribonucleoprotein, resulting in a significant increase in the relevant intramolecular distance. These chemical enhancers were easily integrated into existing CRISPR/Cas biosensing protocols without additional modifications. The detection of Helicobacter Pylori DNA and SARS-CoV-2 RNA showed significantly reduced reaction time and increased sensitivity.
