    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: 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: A contact pin printhead for microfluidic array spot printing can include a printhead chassis with a plurality of micro-pins insertable within respective sockets in the printhead chassis. An individual micro-pin can include a micro-pin tip that can be individually biased in a distal direction toward a target substrate via an elastic mechanical biaser associated with the micro-pin. An individual micro-pin can deposit fluid carried within a cavity therein and onto a target substrate during physical contact therewith at a micro-pin tip. Also, an individual micro-pin can retain fluid carried within the cavity, without depositing, absent physical contact at the micro-pin tip.
