AI Article Synopsis
- A microfabricated Fabry-Pérot interferometer features nanochannels with heights ranging from 6 to 20 nm, allowing for precise examination of liquid behavior.
- Through multiple beam interferometry, the device studies liquids like ethanol and water without the need for fluorescent markers.
- An unusual filling mode for partially wetting water was identified, possibly due to significant gas entrapment within the nanochannels.
Article Abstract
We describe a microfabricated Fabry-Pérot interferometer with nanochannels of various heights between 6 and 20 nm embedded in its cavity. By multiple beam interferometry, the device enables the study of liquid behavior in the nanochannels without using fluorescent substances. During filling studies of ethanol and water, an intriguing filling mode for partially wetting water was observed, tentatively attributed to the entrapment of a large amount of gas inside the channels.
