Enhancement of the peroxidase-like activity of aptamers modified gold nanoclusters by bacteria for colorimetric detection of Salmonella typhimurium

Qingmei Chen et al.

Summary: A colorimetric aptasensor was developed for selective and sensitive detection of Salmonella typhimurium, utilizing dual aptamers modified bovine serum albumin stabilized-gold nanoclusters. The aptasensor showed a wide linear response to S. typhimurium with a low detection limit, and was successfully applied for detection in egg samples.

Cell-based fluorescent microsphere incorporated with carbon dots as a sensitive immunosensor for the rapid detection of Escherichia coli O157 in milk

Yong Zhao et al.

Summary: The study developed a highly sensitive fluorescent immunosensor using CDs-microspheres for the specific detection of Escherichia coli O157:H7 in milk, showing strong fluorescence intensity, good stability, and high uniformity in fluorescence. The immunosensor had a detection limit of 2.4 x 10(2) CFU/mL and could detect spiked E. coli O157:H7 in milk within 30 minutes with good repeatability. Additionally, the method could detect trace amounts of E. coli O157:H7 in real milk samples with 100% accuracy after bacterial enrichment, demonstrating its potential as a rapid and sensitive tool for pathogen detection in milk and other foods.

A novel smartphone-based colorimetric aptasensor for on-site detection of Escherichia coli O157:H7 in milk

Tao Yang et al.

Summary: A smartphone-based colorimetric aptasensor was developed for the detection of E. coli O157:H7 in milk, showing good reproducibility with no cross-reaction for other bacteria. The sensor could detect a concentration of 8.43 x 10^3 cfu/mL of E. coli O157:H7 in pure culture and 5.24 x 10^2 cfu/mL in artificially contaminated milk after 1 hour of incubation.

A highly selective ratiometric fluorescent probe for doxycycline based on the sensitization effect of bovine serum albumin

Lu Ding et al.

Summary: Fluorescent probes with in-situ visual feature have gained attention for detecting doxycycline (DC), a widely used tetracycline antibiotic in animal husbandry. Bovine serum albumin-capped gold nanoclusters (BSA-AuNCs) were used as a ratiometric fluorescent probe to selectively detect DC among tetracycline antibiotics. BSA-AuNCs showed the highest response toward DC, with simple synthesis, short response time (1 min), and low detection limit. This work proposes an efficient strategy for designing fluorescent probes to selectively detect DC among tetracycline antibiotics.
