Abstract: The present disclosure discloses a 1-carboxy-2-hydroxy-3-iminopropane and an extraction method thereof, and belongs to the technical fields of food, health food and medicine.

Abstract: The present disclosure belongs to the technical field of analytical chemistry, in particular to synthesis and application of a nanomaterial for removal of patulin (Pat). The present disclosure adopts 2-Oxin as a substitute template, AM as a functional monomer, and synthetic Fe3O4@SiO2@CS-GO magnetic nanoparticles as a carrier, for preparing a magnetic MIP specific for Pat adsorption by surface imprinting. The addition of Fe3O4 makes the finally prepared molecular imprinted adsorbent material magnetic, thereby facilitating separation of a material from a matrix, eliminating complicated operation steps such as filtration and centrifugation, and facilitating recovery of materials.

Abstract: The present invention discloses a time-resolved immunoquantitation test strip for detecting tetrodotoxin (TTX) in shellfish food, which belongs to the technical field of rapid detection of time-resolved immunoassay. In the present invention, fluorescent microspheres are adopted to replace the traditional colloidal gold; the fluorescent microsphere is used for labeling a TTX antibody complex; by utilizing a competitive immunization method, the fluorescent microsphere, serving as a fluorescent probe, is used for immunochromatography; and by reading the fluorescence value of a detection line on a fluoroimmunoassay instrument, the TTX in shellfish samples can be analyzed quantitatively and rapidly. The time-resolved immunoquantitation test strip of the present invention can be used for detecting the content of the TTX in various types of shellfish food quantitatively and rapidly and is strong in specificity and high in sensitivity, wherein when the concentration of the TTX is 0.

Abstract: The disclosure provides a single-cell-based electrochemical sensor based on a functionalized nano-probe and an application thereof, and belongs to the technical fields of electrochemical sensors and toxin detection. The single-cell-based electrochemical sensor of the disclosure combines a nano-probe and an electrochemical cell-based sensor, conducts functional modification on the nano-probe using Prussian blue, and conducts current signal analysis on a single cell by a micro-operating platform. The disclosure constructs a reliable, easy to operate and highly repeatable single-cell-based electrochemical detection platform, and the current value is determined by electrochemical chronoamperometry to determine damage of a single cell stimulated by toxins, thereby quickly and effectively evaluating the cytotoxicity of fungal toxins, and further enabling application of the fungal toxin toxicity in real-time monitoring and nano-environmental detection in living cells.
