Abstract: Disclosed herein are an imaging module bearing device and base, a microscopic image acquisition device and an adjusting method. The imaging module bearing device includes an imaging lens support, an imaging lens clamping base and an adjustment guide base; an imaging lens clamping base bottom portion is movably clamped between the imaging lens support and the adjustment guide base; and the levelness of an upper surface of the imaging lens clamping base bottom portion relative to an imaging lens support bottom portion can be adjusted until a microscopic imaging module fixed to the imaging lens clamping base is orthogonal to the upper surface of the imaging lens clamping base bottom portion, and the microscopic imaging module is fixed to the imaging lens clamping base.

Abstract: The invention relates to the technical field of mechanical compression, and particularly provides a pressing and retaining device for a spring. The invention aims to solve the problems of inconvenient operation and poor compression accuracy in the existing technical solutions for spring pressing and retaining To this end, a pressing and retaining device for a spring of the invention comprises a spring compression assembly and a spring retaining assembly. The spring compression assembly is configured to be capable of compressing the spring into a set state. The spring retaining assembly is configured to be capable of fixing the spring and maintaining a compressed state of the spring when the spring is compressed into the set state, and to be capable of still fixing the spring and maintaining the compressed state of the spring when the spring retaining assembly and the spring are disengaged as a whole from the spring compression assembly.

Abstract: The present invention relates to a method for constructing a chromatography test strip for triazophos based on molecular imprinting and electrospinning. The present invention combines electrospinning, molecular imprinting and the immunochromatography test strip technology. Molecularly imprinted T-line (detection limit) is prepared on an NC membrane by electrospinning, and goat anti-mouse IgG is used as C-line (quality control line). With fluorescence changes occurring when triazophos hapten-murine IgG/fluorescein isothiocyanate conjugate (THBu-IgG-FITC) fluorescent probe directly competes with the target triazophos to bind to the molecularly imprinted binding site, a chromatography-fluorescence detection method for triazophos based on molecular imprinting and electrospinning is established. The functional material adsorbing triazophos provided by the present invention adopts a virtual template to avoid template leakage, and can be used in immunochromatography to replace a biological antibody.
