Abstract
Marbofloxacin (MBF) was once widely used as a veterinary drug to control diseases in animals. MBF residues in animal food endanger human health. In the present study, an immunochromatographic strip assay (ICSA) utilizing a competitive principle was developed to rapidly detect MBF in beef samples. The 50% inhibitory concentration (IC50) and the limit of detection (LOD) of the ICSAs were 2.5 ng/mL and 0.5 ng/mL, respectively. The cross-reactivity (CR) of the MBF ICSAs to Ofloxacin (OFL), enrofloxacin (ENR), norfloxacin (NOR), and Ciprofloxacin (CIP) were 60.98%, 32.05%, 22.94%, and 23.58%, respectively. The CR for difloxacin (DIF) and sarafloxacin (SAR) was less than 0.1%. The recovery rates of MBF in spiked beef samples ranged from 82.0% to 90.4%. The intra-assay and interassay coefficients of variation (CVs) were below 10%. In addition, when the same authentic beef samples were detected in a side-by-side comparison between the ICSAs and HPLC‒MS, no statistically significant difference was observed. Therefore, the proposed ICSAs can be a useful tool for monitoring MBF residues in beef samples in a qualitative and quantitative manner.

Abstract
An ultrasensitive and broad-specific monoclonal antibody recognising cyproheptadine hydrochloride and six phenothiazines was produced. The 50% inhibition concentration against cyproheptadine hydrochloride was 0.036 ng/mL, and the cross-reactivities for six phenothiazines were from 6.33% to 63.16%. Based on the developed monoclonal antibody, an immunochromatographic strip was established, with the visual detection limits (cut-off values) of seven drugs ranging from 5 to 100 ng/g in feedstuffs. With the strip reader, the 50% inhibition concentration of the developed immunochromatographic strip for seven drugs ranged from 0.570 to 7.750 ng/g. The intra-assay recoveries were from 79.8% to 103.4% with the highest coefficient of variation of 11.3%. The inter-assay recoveries were from 79.0% to 96.6% with the highest coefficient of variation of 12.7%. In summary, the proposed immunochromatographic strip was considered suitable for simultaneously monitoring cyproheptadine hydrochloride and phenothiazines in feedstuffs.

Abstract
An immunosensor for the assay of toxic biological warfare agents is a biosensor suitable for detecting hazardous substances such as aflatoxin, botulinum toxin, ricin, Shiga toxin, and others. The application of immunosensors is used in outdoor assays, point-of-care tests, as a spare method for more expensive devices, and even in the laboratory as a standard analytical method. Some immunosensors, such as automated flow-through analyzers or lateral flow tests, have been successfully commercialized as tools for toxins assay, but the research is ongoing. New devices are being developed, and the use of advanced materials and assay techniques make immunosensors highly competitive analytical devices in the field of toxic biological warfare agents assay. This review summarizes facts about current applications and new trends of immunosensors regarding recent papers in this area.

Abstract
Abstract
Objectives
Fluoroquinolones (FQs) are widely used in aquaculture, and their residues have caused many problems threatening human health. Here, this study aims to develop a colloidal gold immunochromatographic strip based on gold-labeled microwells to screen the residues of FQs on site.
Materials and Methods
The Protein A Magarose Beads affinity chromatography method was adopted to purify the ascites against FQs. By using a strategy of heterologous coating antigen, different coating antigens are applied to detect FQs. The gold-labeled microwell immunochromatographic assay was used to improve the sensitivity of the test strip by the advanced reaction of antigen and antibody.
Results
The antibodies were verified to be of high purity up to 99%, and the titer reached 1:1,024,000. The combination (enoxacin-OVA and the antibody) detected the 4 banned FQs (pefloxacin, PEF; norfloxacin, NOR; lomefloxacin, LOM; ofloxacin, OFL) with IC50 values ranging from 1.3 to 2.1 ng/mL and cross-reactions ranging from 67.3 to 106.1%. The analysis of spiked crucian carp, silver carp, grass carp, and shrimp samples showed that the limit of detection for PEF, NOR, LOM, and OFL was 4 µg/kg. A comparative study with LC–MS/MS demonstrated that the assay provides an effective screening tool for the rapid detection of FQs residues.
Conclusions
The results indicated that the test strip can realize full coverage recognition of the 4 banned FQs and has good accuracy, specificity, reproducibility, and stability; therefore, they are more suitable for rapid detection of FQs in aquatic products.

Abstract
A signal-enhanced LFIA based on tyramine (TYR)-induced AuNPs aggregation has been developed for the sensitive detection of danofloxacin (DAN). In the model, the hydroxyl radical produced by HRP catalyzing H2O2 can trigger the TYR-AuNPs to aggregate on the T or C line for enhancing the detection signal. The linear range of TYR-AuNPs LFIA was 0.25-5 ng mL-1 with the limit of detection (LOD) of 0.032 ng mL-1, and the LOD was 8-fold lower than that of the traditional AuNPs LFIA (0.26 ng mL-1). The TYR-AuNPs LFIA could be used with the naked eyes to qualitatively detect DAN with a cut-off limit of 2.5 ng mL-1, which was 4-fold lower than that of the traditional AuNPs LFIA (10 ng mL-1). The recoveries of TYR-AuNPs LFIA were 86.04-105.14% and 92.41-110.19%, with the coefficient of variation of 1.71-2.05% and 4.42-5.89% in chicken and pork, respectively.

Abstract
INTRODUCTION The plant Pueraria candollei var. mirifica (Airy Shaw & Suvat.) Niyomdham (PM), known by its common Thai name as white Kwao Krua, is sometimes misidentified because it presents similar botanical characteristics to those of Butea superba (red Kwao Krua). The phytochemicals in PM are phytoestrogens in the class of isoflavonoids, but Butea superba contains flavonoids that exhibit androgenic and antiestrogen effects. OBJECTIVES This research aims to develop a simple analytical method for identification and to differentiate PM from red Kwao Krua and other Pueraria species. METHODS A gold nanoparticle-based immunochromatographic assay (ICA) was developed for the detection of kwakhurin (Kwa), a unique compound found in PM. The parameters, including sensitivity, accuracy, precision, and specificity, were validated. All samples were analyzed using ICA and high-performance liquid chromatography with UV detector (HPLC-UV). The results of the two methods were compared for consistency checking. RESULTS The cutoff limit of Kwa detection was 160 ng/mL, which was lower than in the HPLC-UV method. The repeatability and reproducibility of the ICA preparation and assembly showed high precision. The cross-reactivity to related isoflavonoids was less than 0.32%, which implied high specificity of the ICA for Kwa. Moreover, false-positive and false-negative results from other plant extracts were not observed. CONCLUSION The developed ICA is applicable for distinguishing PM from red Kwao Krua and other Pueraria species. This simple analytical method can be applied for the identification of raw PM materials in the industrial and agricultural sectors.

Abstract
Salmonella and Shigella genera are common pathogens that contaminate foods and beverages. Lateral flow assays (LFA) are commonly used to detect these pathogens. However, most of the developed LFAs are for single detection. Simultaneous detection of pathogens is required to reduce cost and time. In this work, 40 nm gold nanoparticles (AuNPs) were synthesized using the seeding growth method as labeling agent. The AuNPs were characterized and conjugated with mouse anti-Gram negative endotoxin antibody. The nitrocellulose membrane HF135 was immobilized with anti-mouse IgG antibody as a control line and two separate test lines with either anti-Shigella or anti-Salmonella antibody, respectively. Color intensity of test lines was observed for positive samples. A milk sample was used as proof of concept to mimic actual contamination. The limit of detection of the LFA was 3.0 × 106 CFU/mL for multiplex detection of Shigella flexneri and Salmonella Typhi and for both single detections. The result was comparable with the enzyme-linked immunosorbent assay (ELISA) analysis. The produced LFA could differentiate between Shigella flexneri, Shigella boydii, Salmonella Enteritidis, and Salmonella Typhi. The developed LFA was able to identify Shigella flexneri and Salmonella Typhi with good sensitivity in milk samples, thus, beneficial to ensure the safety of food before entering the market.

Abstract
Valnemulin (VAL) and tiamulin (TIA) are pleuromutilin antibiotics used primarily for treating bacterial infections in swine or other food animals. Furthermore, VAL and TIA are also employed as feed additives to promote animal growth. However, the illegal use of VAL and TIA could cause a series of hazards to consumers. Here, VAL was designed to be conjugated with bovine serum protein to prepare immunogen. A highly sensitive monoclonal antibody that recognized both VAL and TIA has been successfully produced. Moreover, an immunochromatographic strip assay for rapidly screening VAL and TIA in porcine liver was established with visual detection limits (cutoff values) of 50 and 25 ng/g, respectively. The IC50 values calculated from the equation of the standard curve were 6.06 and 3.45 ng/g and the limits of detection were 0.96 and 0.29 ng/g for VAL and TIA. According to the recovery experiment results, the test strip exhibited acceptable accuracy and precision. Generally, the proposed strip provided a practical tool for the detection of VAL and TIA. PRACTICAL APPLICATION: We produced a highly sensitive monoclonal antibody and developed an immunoassay strip for simultaneously monitoring TIA and VAL. Additionally it was preliminarily confirmed that the rapid detection tool was suitable for screening TIA and VAL in porcine liver.
