Amino-Modified Magnetic Nanoparticles Magnetophoretic Chromatography Combined with Enzyme-Aptamer Colorimetric Photothermal for the Detection of Escherichia coli O157:H7 in Sea Cucumber Peptides

A Convenient Colorimetric Biosensor Based on Immunomagnetic Separation and G-Quadruplex DNAzyme Signal Amplification for Ultrasensitive Detection of Vibrio parahaemolyticus in Seafood

A Novel Bimetallic Nanozyme-Driven Fluorescence–Colorimetric Dual-Mode Platform for the Rapid Detection of Escherichia coli O157:H7 in Meat Products

Foodborne diseases pose a severe threat to human health. As a critical meat-borne pathogen, Escherichia coli O157:H7 (E. coli O157:H7) can trigger severe illnesses such as hemorrhagic enteritis, threatening public safety and causing a huge economic impact on the meat industry. However, previous detection methods have s...

Mannose-engineered Eu-MOF for ratiometric fluorescent/colorimetric dual-detection and inhibition of E. coli.

Reliable detection and fast inhibition of Escherichia coli (E. coli) are critical for public health and food safety, so the detection-inhibition-integrated strategies become critical. Herein, a mannose-engineered 3,5-dicarboxyphenylboronic acid/curcumin dual-ligand Eu-metal-organic framework (Eu-MOF) was designed as dc...

Dual-ligand quantum dot biosensor combining IgY antibodies and DNA aptamers for rapid, on-site detection of staphylococcal enterotoxin A (SEA) in food matrices.

A type of magnetically induced self-assembled electrochemical aptamer nanobiosensor for ultrasensitive detection of hypoxia-inducible factor 1α protein

Background Hypoxia-inducible factor 1α (HIF-1α) protein has been identified as an aggressive malignant phenotype marker for numerous tumors; therefore, the detection of HIF-1α has become increasingly significant. Methods In this work, we developed a type of magnetically induced self-assembled electrochemical aptamer na...

A Monolithic, Thiol-Functionalized Au-Based Bio-CMOS Aptasensor for Rapid, Label-Free Detection of Escherichia coli O157:H7 in Patient-Derived and Hospital-Acquired Specimens

Because the patient-derived and hospital-acquired cohorts were assembled for pilot analytical and matrix-tolerance characterization rather than for diagnostic-accuracy determination, these results establish detectability and matrix robustness in real clinical and environmental specimens rather than clinical diagnostic...
