A system and method for the real time determination of microbial growth in or on perishable products. The system can predict the extent of microbial growth, e.g., whether food is spoiled, in real time by measuring chemicals released, e.g., CO.sub.2, from the perishable product during microbial growth. The output from a sensor can be correlated to the extent of microbial growth, i.e., spoilage, and provide information about the extent of microbial growth to the user, for example, through their smart devices.

A pathogen detection system includes a pathogen sensing adaptor that detect pathogens present in the breathing circuit associated with a ventilated patient. A pathogen sensing adaptor may include a conduit, removable cartridges with testing strips, an optical sensor, and communication circuitry. Upon detecting a colorimetric change on the testing strip, the optical sensor generates a signal indicative of the presence and/or level of pathogens.

A gas analysis device includes a light source configured to emit laser beam to a target gas, a reflection body which reflects the laser beam, a light reception device that receives the laser beam reflected by the reflection body, a container which contains the light source and the light reception device, and an alignment mechanism that includes an insertion member inserted from outside of the container to inside of the container to move, along a plane intersecting with the irradiation direction of the laser beam, at least any one of the light source and the light reception device.

Analyte collection and testing systems and methods, and more particularly to disposable oral fluid collection and testing systems and methods. Described herein are methods and apparatuses to achieve significant improvements in the detection of fluorescence signals in the reader.

An inspection apparatus is provided that comprises an optical target including a solid host material and a fluorescing material embedded in the solid host material. The solid host material has a predetermined phonon energy HOST.sub.PE. The fluorescing material exhibits a select ground energy level and a target excitation (TE) energy level separated from the ground energy level by a first energy gap corresponding to a fluorescence emission wavelength of interest. The fluorescing material has a next lower lying (NLL) energy level relative to the TE energy level. The NLL energy level is spaced a second energy gap FM.sub.EG2 below the TE energy level, wherein a ratio of the FM.sub.EG2/HOST.sub.PE is three or more.

Disclosed are a detection method and detection system using suspension liquid biochip detection. The detection method using suspension liquid biochip comprises the following steps: an excitation step and a signal acquisition step. In the excitation step, a laser light emitted by a single laser device is used to excite a classification fluorescence of nanocrystalline fluorescent microspheres and a report fluorescence of an object to be detected; and in the signal acquisition step, fluorescence detection signals are obtained through multiple acquisition channels, respectively. In the present invention, the classification fluorescence in the nanocrystalline fluorescent microspheres and the report fluorescence in the object to be detected in a sample are excited by a single laser device, which is convenient for operation and reduces the production cost of the system, thereby reducing the detection cost.

A portable and completely self-contained apparatus(20) for detecting analyte and the methods of use thereof is described. The apparatus (20) includes a microfluidic cartridge driver unit (30), an optical inspection unit (32), and a control unit (28) and a power supply unit, which can run the binding and detection of the analyte without any fluidic interfaces to the instrument.
