Abstract: A method for preparing fluorescent-encoded microspheres coated with metal nanoshells is disclosed herein. By using SPG method, metal nano-material modified with a certain ligand is used as a new surfactant in the emulsification process, and different kinds and different amounts of fluorescent materials are doped into polymer microspheres to prepare fluorescent-encoded microspheres with different fluorescent-encoded signals and uniformly coated metal nanoshells in one step. The prepared fluorescent-encoded microsphere comprises a metal nanoshell, a polymer, and a fluorescent-encoded material. The fluorescent-encoded microsphere has a particle size of 1 ?m˜20 ?m, CV of less than 10%, which can be used for protein/nucleic acid detection.

Abstract: The invention provides a detection device, comprising a fluid sample collecting chamber, the collecting chamber including an opening, a testing element is arranged in the collecting chamber, and the testing element is used to test the presence of the analyzed substance in the fluid sample; the detection device further comprises a cover body used to close the opening of the collecting chamber; wherein the cover body includes an elastic card used to engage the opening of the collecting chamber, when the cover body closes the opening of the collecting chamber, the elastic card engages the outer wall of the opening of the collecting chamber, thereby fixing the cover body on the collecting chamber.

Abstract: The invention provides a device and method for distinguishing smoking an e-cigarette from smoking a cigarette. The device includes a test strip used to detect nicotine or its analogues in a sample; and a test strip used to detect glycerine in the sample. The device and method of the invention can be used to effectively distinguish which cigarette a user is smoking, the e-cigarette or a tobacco product. This is conductive to providing more accurate treatment and intervention for nicotine abusers.

Abstract: The present invention relates to the field of biochemical detection, and in particular to a reading apparatus for reading an assay result on a testing element. The reading apparatus comprises a first light-emitting element, a first photodetector and a light blocking element, wherein the first light-emitting element emits light and illuminates one or more corresponding areas of the testing element, the first photodetector receives light from one or more corresponding areas of the testing element, and the light blocking element guides a path of light emitted from a light emitting element and/or from a testing element. The light blocking element separates photodetectors in separate spaces, including a first light blocking element and a second light blocking element, wherein the first light blocking element is located between the first light-emitting element and the first photodetector, to guide the light emitted from the light emitting element to illuminate the testing element.
