A fluorometric and electrochemical dual-mode method is described for sensitive and specific detection of tetracycline (Tc). A novel nanoprobe was designed that is making use of a Tc-specific aptamer (apta), carbon nitride quantum dots (CNQDs) and silver nanoparticles (AgNPs). The aptamer was linked to the CNQDs which then were used as templates to synthesize the apta-CNQD@AgNP nanocomposites. The blue fluorescence of the nanocomposites (with excitation/emission maxima at 365/440 nm) is quenched....

The transfer set in calibration transfer can be further refined by backward refinement (BR) method. The BR includes many loops, in each of which the sample can be removed which reduces the RMSEV best. Then, this procedure can be repeatedly executed many times so that many subsets of samples can be obtained. Finally, the sample subset with a small value of RMSEV can be chosen as the best sample subset. Two batches of datasets including corn and wheat datasets have been applied to testing this met...

Abstract Amine-responsive bilayer films were developed by using agar (AG), anthocyanins (AN), gellan gum (GG) and TiO2 nanoparticles for visual monitoring of meat spoilage. The AG-AN layer worked as the sensing layer to volatile amines, while GG-TiO2 layer served as the light barrier layer and simultaneously the conducting layer to improve the illumination stability and electrochemical writing ability of the AG-AN layer, respectively. The Scanning electron microscopy (SEM) images and X-ray diffr...

Abstract Currently, the detection of pesticide is critical for food safety assurance, but it is still challenging due to the presence of biological interferents from complex food matrix. In this study, we developed an optical anti-interference surface-enhanced Raman scattering (SERS) aptasensor system for trace detection of acetamiprid. 4-(Mercaptomethyl) benzonitrile (MMBN) containing C N bond was used as Raman tag to provide a sharp peak (2227 cm−1) in the Raman-silent spectral window (1800-28...

Abstract A novel ratiometric fluorescence sensor based on fluorescence resonance energy transfer (FRET) between MoS 2 QDs and AuNCs was developed for nitrite detection in sausages. The MoS 2 QDs-AuNCs nanocomposite exhibited dual emission peaks at 430 nm and 615 nm under 365 nm excitation. With addition of nitrite, the fluorescence of AuNCs was quenched due to the agglomeration of AuNCs, whereas the emission of MoS 2 QDs increased for the blocked FRET. With this strategy, nitrite was detected in...

Abstract This study was performed to develop a low-cost smart system for identification and quantification of adulterated edible bird's nest (EBN). The smart system was constructed with a colorimetric sensor array (CSA), a smartphone and a multi-layered network model. The CSA were used to collect the odor character of EBN and the response signals of CSA were captured by the smartphone systems. The principal component analysis (PCA) and hierarchical cluster analysis (HAC) were used to inquiry the...

A smart handheld device based on colorimetric sensor array and smart cellphone was constructed to discriminate geographical origins of edible bird’s nest (EBN). Three hundred and twenty EBN samples were collected from Malaysia and Indonesia. The colorimetric sensor array consists of chemo-response dyes and was used to capture the odor molecule. The smart cellphone was used to obtain images and to extract red, green and blue colors using in-house software before and after contact with each sample...

Abstract An electrode modified with pyridine functionalized gold nanoparticles and three-dimensional graphene was prepared and employed for the voltammetry determination of hexavalent chromium. Graphene oxide was electrochemically reduced on glassy carbon electrode. Gold nanoparticles were electrodeposited on the surface of graphene under constant potential. Pyridine group anchored on gold nanoparticles by self-assembly. The modified materials were characterized by scanning electron microscopy, ...

The present work aimed at evaluating the efficacy of gum Arabic–based edible coating enriched with red and white roselle extracts, on the postharvest quality of blueberry fruits during storage at 4 ± 0.5 °C. Physicochemical, phytochemicals, antioxidant capability, decay percent, and microbiological analyses of coated and uncoated blueberries were performed. The change rates of polyphenol oxidase (PPO) and guaiacol peroxidase (POD) activity were also measured. The coatings (gum Arabic with or wit...

The feasibility of rapid identification of Lactobacillus species using near-infrared spectral features coupled with chemometrics was investigated. First, bacterial colonies of 11 Lactobacillus strains covering four species (Lactobacillus casei, Lactobacillus reuteri, Lactobacillus brevis, and Lactobacillus fermentum) were cultured using the spread-plate technique. Near-infrared spectra data of the Lactobacillus species were collected directly from the bacterial colonies. Second, 10 wavenumbers w...
