Abstract
Acrylamide (AA), an odorless and colorless organic small-molecule compound found generally in thermally processed foods, possesses potential carcinogenic, neurotoxic, reproductive, and developmental toxicity. Compared with conventional methods for AA detection, bio/chemical sensors have attracted much interest in recent years owing to their reliability, sensitivity, selectivity, convenience, and low cost. This paper provides a comprehensive review of bio/chemical sensors utilized for the detection of AA over the past decade. Specifically, the content is concluded and systematically organized from the perspective of the sensing mechanism, state of selectivity, linear range, detection limits, and robustness. Subsequently, an analysis of the strengths and limitations of diverse analytical technologies ensues, contributing to a thorough discussion about the potential developments in point-of-care (POC) for AA detection in thermally processed foods at the conclusion of this review.

Abstract
As a toxic substance on human health produced in food thermal treatment, simple analytical approaches are highly desired for the detection of acrylamide (ACR) in foods. With the aid of exonuclease III (Exo III), a simple fluorescence sensor was proposed based on carboxyfluorescein-labeled double-stranded DNA (FAM-dsDNA) and a cationic conjugated polymer (PFP). Fluorescence resonance energy transfer (FRET) efficiency between FAM and PFP was changed with and without ACR. When ACR was present, ACR and single-stranded DNA (P1, ssDNA) formed an adduct, allowing free FAM-labeled complementarity strand DNA (P2, FAM-csDNA) to appear in the solution and avoiding the digestion of P2 by Exo III. After the addition of PFP, the interaction of PFP and FAM induced strong FRET. Under optimized conditions, ACR was detected with a limit of detection (LOD) of 0.16 μM. According to this biosensor, a LOD of 1.3 μM in water extract samples was observed with a good recovery rate (95-110 %).

Abstract
Acrylamide is toxic aliphatic amide formed via the Maillard reaction between asparagine and reducing sugars during thermal processing of food. Herein, a specific nanobody termed Nb-7E against the acrylamide derivative xanthyl acrylamide (XAA) was isolated from an immunized phage display library and confirmed to be able to detect acrylamide. First, an indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) was established for acrylamide with a limit of detection (LOD) of 0.089 μg/mL and working range from 0.23 to 5.6 μg/mL. Furthermore, an enhanced electrochemical immunoassay (ECIA) was developed based on the optimized reaction conditions. The LOD was as low as 0.033 μg/mL, threefold improved compared to that of ic-ELISA, and a wider linear detection range from 0.39 to 50.0 μg/mL was achieved. The average recoveries ranged from 88.29 to 111.76% in spiked baked biscuits and potato crisps. Finally, the analytical performance of the ECIA was validated by standard ultraperformance liquid chromatography tandem mass spectrometry (UPLC-MS/MS).

Abstract
Purification of antibodies has become a critical factor in antibody production. A high-purity specific antibody against antigens, especially small molecules, seems to be difficult to obtain, even with the help of a protein A affinity column, which is a conventional and broadly used ligand for the separation of antibody and non-antibody proteins. Therefore, it is urgent to develop a cheap, simple, efficient, and stable method to separate the specific antibody from other antibodies. In this study, to improve the sensitivity and accuracy of immunoassay results, enrofloxacin (ENR) was grafted onto polyethylenimine (PEI) by the abundant amino groups and then the whole ligand (ENR-PEI) was conjugated to CNBr-Sepharose 4B to prepare the affinity column for the purification of the specific antibody against ENR from polyclonal antibodies. Scanning electron microscopy and Fourier transform infrared spectroscopy verification showed that Sepharose 4B was successfully modified by ENR-PEI with excellent uniformity. The capacity of the prepared column could reach to 6.15 mg of specific antibody with high purity per milliliter resin due to the high coupling ratio (49.3:1) of ENR on PEI, and the IC50 value of the antibody after purification was 47.58 ng/mL with a lowest limit of detection (IC10) of 1.099 ng/mL-18 times lower than those of the antibody purified through the protein A column. All the results showed that this new kind of resin could be used as the potential ligand in the purification of the trace-specific antibody against antigens in complex mixtures with high efficiency and specificity.

Hapten Design and Monoclonal Antibody to Fluoroacetamide, a Small and Highly Toxic Chemical. Biomolecules 2020; 10:biom10070986.

Abstract
Fluoroacetamide (FAM) is a small (77 Da) and highly toxic chemical, formerly used as a rodenticide and potentially as a poison by terrorists. Poisoning with FAM has occurred in humans, but few reliably rapid detection methods and antidotes have been reported. Therefore, producing a specific antibody to FAM is not only critical for the development of a fast diagnostic but also a potential treatment. However, achieving this goal is a great challenge, mainly due to the very low molecular weight of FAM. Here, we design two groups of FAM haptens for the first time, maximally exposing the fluorine or amino groups, with the aid of linear aliphatic or phenyl-contained spacer arms. Interestingly, whereas the hapten with fluorine at the far end of the hapten did not induce an antibody response to FAM, the hapten with an amino group at the far end and phenyl-contained spacer arm triggered a significantly specific antibody response. Finally, a monoclonal antibody (mAb) named 5D11 was successfully obtained with an IC50 value of 97 μg mL−1 and negligible cross-reactivities to the other nine functional and structural analogs.

Abstract
Objective To produce, purify, and characterize a polyclonal antibody against acrylamide (anti-AA) for an application to immunochromatographic strip tests for AA. Materials and Methods Polyclonal anti-AA was prepared by injecting N-acryloxysuccinimideconjugated bovine serum albumin hapten-antigen into New Zealand white rabbits. The antibody was purified using protein A, characterized using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and conjugated with gold nanoparticles (AuNP). The conjugated antibody was then characterized using UV-Vis and FTIR spectroscopy and transmission electron microscopy (TEM). Immunochromatographic strip tests were performed using sample pads, conjugated pads, test zones, control zones, and absorbent pads. Strip tests were finally validated using standard AA solutions followed by the application of various concentrations of coffee samples. Results Using SDS-PAGE, the purified anti-AA antibody was resolved at 50 and 25 kDa, indicating the presence of heavy and light chains, respectively. The conjugation of anti-AA with AuNP was confirmed using wavelength shifts in UV-Vis and FTIR spectra, and TEM analyses revealed increased diameters of AuNPs after conjugation. The immunochromatographic strip test was sensitive to 1 mgml-1 standard AA. Various concentrations of coffee samples resulted in red color differences in the test zone. High and low coffee concentrations produced thick and thin red lines, respectively. Conclusion Purified anti-AA can be conjugated with AuNP to produce strip tests for detecting AA in coffee samples. The present immunochromatographic strip tests quantitatively showed increasing intensities of red lines with increasing AA concentrations.

Abstract
Since the discovery of high-level acrylamide (Acr) contamination in food, extensive international studies have focused on its toxicity and detection. By using a novel antigen synthetic strategy, we have successfully obtained a specific antibody towards acrylamide (Acr-Ab). Herein, the Acr-Ab and its interactions with Acr were characterized. Enzyme-linked immunosorbent assay (ELISA) and dynamic light scattering (DLS) investigations revealed that the conformational structure of Acr-Ab was sensitive to buffers. It showed a satisfied immunoreactivity in phosphate buffered saline (PBS), but denatured in water. In natural state, Acr-Ab had a trend of getting aggregation through their complementarity determining regions (CDRs). Adding Acr leaded to their disassembling. While mixed with Acr, Acr-Ab exhibits not only a fast, high-specific, and reversible non covalent binding (by surface plasmon resonance, SPR), but also a covalent alkylation with Acr through cysteine and histidine residues on its surface, as demonstrated by high-performance liquid chromatography (HPLC). Neither of the two reactions involves conformational change in secondary or tertiary structures as shown in circular dichroism spectra (CD). These special properties of Acr-Ab and the entirely new interaction mode with Acr will extend our knowledge of Acr related biosystem and facilitate the development of new detection strategies for Acr.

Abstract
The high level of acrylamide in widely consumed processed foods poses a potentially significant risk to human health, which has led to an increasing demand for rapid, simple, and selective analytical methods. In the present work, several haptens for acrylamide were designed in an attempt to prepare antibodies with acrylamide affinity, but they failed their purpose. However, a polyclonal antibody was produced against 4-mercaptophenylacetic acid (4-MPA)-derivatized acrylamide, which showed high binding affinity to the derivative. As acrylamide easily reacted with 4-MPA at high derivation yield, a competitive indirect enzyme-linked immunosorbent assay (ciELISA) for acrylamide via a preanalysis derivatization was developed. The derivatization and ELISA conditions were fully optimized to produce a method for acrylamide assay that exhibited an IC50 of 2.86 μg/kg, limit of detection at 0.036 μg/kg, and linear range of 0.25-24.15 μg/kg. The results of preanalysis recovery tests of acrylamide-spiked food samples and screening of blind food samples by both ciELISA and HPLC-MS/MS indicated the proposed ciELISA's good accuracy and reliability. This method was thus deemed suitable for routine acrylamide screening in food samples at low cost.

Abstract
The analytical performance and evaluation of a kit-based ELISA for the determination of acrylamide in fried potato and corn chip samples are described. The sample homogenate is subjected to clean-up using SPE, followed by analyte derivatization and ELISA detection. Accuracy, precision and linearity of the ELISA procedure have been validated using spiked samples. Analytical recovery ranged from 91.8% to 96.0% with coefficients of variation below 15%. Good linearity over a wide range of dilution and minimal assay drift was observed within a microtiter plate. IC50 value of the calibration curve was 110 ng/mL, with the limit of detection about 5 ng/mL and dynamic range from 10 to 1000 ng/mL. The high specificity of the ELISA was demonstrated by cross-reactivity study using 11 potential cross-reactants. A good correlation between the results obtained from the ELISA and GC-MS within the concentration range 120-1500 μg/kg was found in the chip samples (r=0.992, n=120). The data demonstrate that the evaluated and validated ELISA has a potential utility in a quick, simple and reliable acrylamide screening analysis for the medium- and large-sized food companies, as well as for residue laboratories and the food industry dealing with improving the chemical safety of foods available to the consumer.

Abstract
Methods applied in acrylamide quantification in foods have been reviewed in this paper. Novel analytical techniques like capillary electrophoresis (CE), immunoenzymatic test (ELISA) and electrochemical biosensors, which can replace traditional methods like high performance liquid chromatography (HPLC) and gas chromatography (GC) were presented. Short time of analysis and high resolution power of electrophoretic techniques caused that they became routinely used in food analysis apart from high performance liquid chromatography and gas chromatography. Application of modern chromatography methods like ultra performance liquid chromatography (UPLC) in acrylamide quantification considerably shortened the time of analysis and decreased the consumption of indispensable reagents. The most promising approaches to acrylamide quantification in foods are electrochemical biosensors and immunoenzymatic tests. In contrast to chromatography and electrophoretic methods they require neither expensive equipment nor time consuming sample preparation and allow for fast screening of numerous samples without the usage of sophisticated apparatuses. Because of many advantages such as miniaturization, rapid and simple analysis, and high sensitivity and selectivity, biosensors are thought to replace conventional methods of acrylamide quantification in food.

In this work, a polyclonal antibody for acrylamide (AA) was obtained by immunization of rabbits with N-acryloxysuccinimide (NAS) and keyhole limpet hemocyanin (KLH) conjugate. A direct enzyme-linked immunosorbent assay (ELISA) based on this antibody was developed with enhanced chemiluminescent (ECL) detection of AA in food samples. Assay conditions, such as concentrations of antibody and enzyme conjugate and competition time, were optimized. The effects of ionic strength and pH value were investigated. The optimized ECL-ELISA system allowed AA determination in a linear working range of 26.3-221.1 ng mL(-1) with an IC(50) value of 60.6 ng mL(-1) and a limit of detection of 18.6 ng mL(-1). Good recoveries with spiked food samples were obtained with a recovery range from 74.4 to 98.1%, and these results correlated well with those obtained using an HPLC method. This indicates that ECL-ELISA is applicable to the specific detection and routine monitoring of AA in food samples.
