The present disclosure relates to a device including a reagent portion in which a chemiluminescent indicator and a chemiluminescent substrate for the indicator are disposed, and a base on which the reagent portion is formed. The chemiluminescent indicator and the chemiluminescent substrate are disposed independently from each other in the reagent portion in such a manner that the chemiluminescent indicator and the chemiluminescent substrate can react with each other when a sample is supplied to the reagent portion. The present disclosure also relates to a remote diagnosis system including an imaging terminal for detecting a luminescent signal generated when a reagent is supplied to the device and an information processing unit for processing luminescent signal data obtained by the imaging terminal. The imaging terminal and the information processing unit can bi-directionally communicate with each other via a network.

A method for preparing a chemiluminescent hydrogel is disclosed, belonging to the field of luminescent materials. The method for preparing a chemiluminescent hydrogel includes the steps of: slowly adding chitosan to an acetic acid solution, stirring at room temperature until completely dissolved, adding a cobalt chloride solution, followed by a polyvinyl alcohol (PVA) solution, sufficiently stirring, ultrasonically defoaming, and subjecting a resulting mixture to an alkaline bath treatment with an alkaline solution, adding N-(4-aminobutyl)-N-ethylisoluminol (ABEI), and stirring with a hydrogen peroxide solution to obtain the chemiluminescent hydrogel. The synthesized hydrogel has the advantages of high luminous intensity and long duration. In the process, a high-water-cut polymer with a three-dimensional network structure obtained by chemical crosslinking with the addition of PVA features excellent biocompatibility, high elasticity, and nontoxicity, and is one of biomedical materials with application potential.

Graphene quantum dots are functionalized by covalently bonding a corrosion inhibitor molecule thereto. In a useful method, a corrosion inhibitor compound is blended with a graphene quantum dot-tagged corrosion inhibitor compound, and the blend is applied to a metal surface, such as the interior of a carbon steel pipe. The blend inhibits corrosion arising from contact with produced water generated by hydrocarbon recovery from one or more subterranean reservoirs. The produced water having the blend dispersed therein is irradiated with a source of light having a selected first range of wavelengths, and the luminescent emission of the graphene quantum dot-tagged corrosion inhibitor is measured at a selected second range of wavelengths, thereby providing for real-time measurement of corrosion inhibitor concentration within the pipe.
