Salmonella Detection Performance Data for a Rapid Chromogenic Assay

A 1.1 MB document details a label-free, equipment-free detection method for Salmonella spp. The assay, developed by Chang Liu and uploaded in 2026, achieves a limit of detection of 12 CFU/ml within 1 hour and shows no cross-reactivity with four non-target bacterial species.

Use Cases

• Benchmarking new rapid detection methods based on the reported 12 CFU/ml limit of detection.
• Evaluating assay specificity based on the described non-reactivity with Shigella flexneri, Enterobacter cloacae, Listeria monocytogenes, and Escherichia coli.
• Designing portable biosensor platforms based on the described RPA and G-quadruplex/hemin DNAzyme integration method.
• Assessing time-to-result efficiency for food safety monitoring based on the 1-hour completion time.

Strengths

• Specific performance metrics are provided, including a 12 CFU/ml limit of detection and a 1-hour process time.
• Assay specificity is validated against four named non-target bacterial species.
• The method is described as label-free and equipment-free, suggesting potential for field use.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The data is contained in a 1.1 MB DOCX file, which may require conversion for analysis.
