Abstract
Systems for biological sensing that include, in one implementation, a sensor, a filter, a pump, and a flow channel. The sensor is configured to test a gas sample. The sensor includes an optical cavity. The filter is configured to filter the gas sample. The flow channel is formed by at least the optical cavity, the filter, and the pump. The pump is configured to generate a negative pressure differential inside the flow channel.
Claims17
A system for biological sensing, the system comprising:
- a sensor configured to test a gas sample, wherein the sensor including an optical cavity,
- wherein the sensor is configured for cavity ring-down spectroscopy;
- a filter configured to filter and release the gas sample;
- a pump;
- and
- a flow channel formed by at least the optical cavity, the filter, and the pump,
- wherein the pump is configured to generate a negative pressure differential inside the flow channel, and
- wherein the filter is positioned at an end of the flow channel.
