The present disclosure belongs to the technical fields of nanoscience and fluorescence sensing, and specifically relates to a preparation method of a paper-based sensor for detecting an ammonia gas, and a use of the paper-based sensor. In the present disclosure, Zn(PA)(BPE) is first prepared, and a porous structure on a surface of the Zn(PA)(BPE) is used to adsorb an ammonia gas to improve a reaction sensitivity of the ammonia gas; then a Zn(PA)@CNQD ratiometric fluorescent substance is prepared from Zn(PA)(BPE) and CNQD through embedding, and finally dissolved in ultrapure water (UPW) to obtain a solution; and the solution is added dropwise on a filter paper, and the filter paper is purged with nitrogen, such that the solution is loaded on the filter paper to obtain a ratiometric fluorescent paper-based sensor.

In the present disclosure, a temperature-sensitive inner layer solution, a deformation intermediate layer solution, and a rigid outer layer solution are first prepared and spray-coated layer by layer on a surface of a fruit or vegetable, such that three preservative film layers are produced successively and can be used for the preservation of the fruit or vegetable.

Three-layer fruit or vegetable preservative film with temperature-controlled release under mechanical driving power, and preparation method thereof

A color sorting method for small-grain agricultural products combining an area scanning photoelectric characteristic and a line scanning photoelectric characteristic is provided. The present invention obtains an area scan image of small-grain agricultural product materials on a conveyor belt by using an area scan camera, which can accurately extract area array features of the materials and realize accurate identification of the unqualified materials. At the same time, the present invention can provide key parameters for accurate positioning during free falling of the materials while identifying the unqualified materials by using the area scan image, and can cooperate with the line scan positioning camera and the pneumatic nozzle to achieve high-speed elimination of the unqualified materials.
