Abstract: A system for gas sensing of a biological specimen can include a chamber, such as to receive the biological specimen therewithin. The system can also include a gas sensing unit to be coupled to the chamber and separated therefrom by a moveable separator. A gas sensor included in the gas sensing unit can be selectively exposed to a fluid headspace of the first chamber, such as a gas environment associated with the biological specimen, upon modification or moving of a separator.

Abstract: An incubation system for gas detection of a biological specimen can include a gas or optical sensor. The sensor can be arranged to be placed in communication with at least one biological specimen vessel for generating an electrical response signal indicating a chemical characteristic associated with the specimen. The specimen can be incubated in a temperature-controlled chamber, such as within a shelf defining a plurality of receptacles. Processing circuitry can be included or used such as to place the sensor and at least one biological specimen vessel in communication with each other.

Abstract: A target gas composition, such as within ambient gas in an environment, can be detected using a gas chemical detector. A functionalized region of the gas chemical detector can be exposed to the ambient gas. The functionalized region can include an optical property indicative of the target gas composition. An optical response signal can be generated based on the optical property and indicative of the target gas composition within the ambient gas in the environment using the functionalized region. An electrical property can be electrochemically transduced, the electrical property indicative of the target gas composition into an electrical response signal. Both the electrical and optical properties can be used together to determine a presence or other characteristic of a target gas in an ambient environment, such as can be produced by a bacteria or infectious agent of interest.

Abstract: An imaging unit can be configured for biological specimen sensing inside an incubator. Such an imaging unit can include an imager in communication with one or more biological specimen vessels for generating a corresponding specimen image of a specimen. Processing circuitry can control the imager to generate the specimen image. This can include controlling at least one of the imager and the individual vessel to locate the vessel in a field of view of the imager for obtaining the specimen image. The specimen image can be image-processed such as to determine an indication of a biological characteristic associated with the specimen.
