Here, we report gold nanoparticle-coated starch magnetic beads (AuNP@SMBs) that were prepared by in situ synthesis of AuNPs on the surface SMBs. Upon functionalization with a specific antibody, immuno-AuNP@SMBs found to be effective separating and concentrating target pathogenic bacteria, Escherichia coli O157:H7, from an aqueous sample as well providing hotspot for surface-enhanced Raman scattering (SERS)-based detection. We employed bifunctional linker protein, 4× gold-binding...

Abstract Graphene has emerged as one of the most promising materials for next‐generation gas sensor platforms due to its high flexibility, transparency, and hydrophobicity. However, graphene shows inherent low selectivity in sensing. This led extensive development noble‐metal decoration on modulate surface chemistry enhanced selectivity. While noble metals such Pt, Pd, Au have widely been employed functionalize surface, non‐noble metal remained underexplored. Here, an unprecedented...

The techno-functional properties of ovomucin as a gel-forming agent and its biological are well-known. aim the present study was to investigate antioxidant activity in hydrolysate using radical scavenging assays. Electrophoresis showed that isolated from whole egg well separated. Ovomucin hydrolysis carried out microbial protease according different incubation times. These hydrolysates exhibited 85% measured by 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) assay after 2 h with...

Lactic acid bacteria biofilms can be used to reduce foodborne pathogen contamination in the food industry. However, studies on growth inhibition of pathogens by inducing biofilm formation antagonistic microorganisms abiotic surfaces are rare. We developed a desiccation-tolerant antimicrobial probiotic biofilm. Lactobacillus sakei M129-1 and Pediococcus pentosaceus M132-2 isolated from fermented Korean foods were found exhibit broad-spectrum antibacterial activity against Bacillus cereus,...

Enrofloxacin (ENR) is a veterinary antibiotic used to treat bacterial infections in livestock. It chiefly persists foods and dairy products, which turn pose severe risks human health. Hence it very important detect the ENR products safeguard Herein, we attempted develop single-step detection lateral flow immunochromatographic assay (LFIA) using gold nanoparticles (AuNPs) for rapid on-site of milk samples. An anti-enrofloxacin monoclonal antibody (ENR-Ab) was conjugated with AuNPs specific...

This study aimed to inhibit Escherichia coli (E. coli) O157:H7 artificially contaminated in fresh meat using bacteriophage. Among 14 bacteriophages, the highly lytic bacteriophage BPECO19 strain was selected E. samples. Bacteriophage significantly reduced bacterial load vitro a multiplicity of infection (MOI)-dependent manner. completely inhibited only 10 min by treatment 10,000 MOI BPECO19.

A colorimetric polydiacetylene (PDA) paper strip sensor that can specifically recognize Bacillus thuringiensis (BT) HD-73 spores is described in this work. The target-specific aptamer was combined with PDA, and the aptamer-conjugated PDA vesicles were then coated on polyvinylidene fluoride (PVDF) strips by a simple solvent evaporation method. PDA-aptamer be used to detect target without any pre-treatment. Using strip, presence of BT directly observable naked eye based unique blue-to-red...

Norovirus infections were detected in 114 of 762 children with acute gastroenteritis South Korea from November 2005 to 2006. Seasonality peaks December, March, and October also assessed this study. We identified seven noroviral genotypes (GI-6, GII-2, GII-3, GII-4, GII-5, GII-6, GII-8) a C1-120 strain showing low identity (79.3%) GII-13 GII-17.
