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.
