Abstract: A gating mechanism that uses a capillary stabilized liquid as a reversible, reconfigurable gate that fills and seals pores in the closed state, and creates a non-fouling, liquid-lined pore in the open state is disclosed. Theoretical modeling and experiments demonstrate that for each transport substance, the gating threshold—the pressure needed to open the pores—can be rationally tuned over a wide pressure range. This enables realizing in one system differential response profiles for a variety of liquids and gases, even letting liquids flow through the pore while preventing gas from escaping. These capabilities allow dynamic modulation of gas-liquid sorting and to separate multi-phase mixtures, with the liquid lining ensuring sustained antifouling behavior.

Abstract: In a general aspect, a system includes a plurality of diamond nanowires disposed on the surface of a diamond substrate, at least some of the nanowires including a color center. The system also includes a light source configured to illuminate at least one of the plurality of nanowires with excitation light at a wavelength corresponding to an excitation wavelength of the color center included in the illuminated nanowire; and an optical receiver configured to receive a fluorescence emitted from the color center included in the illuminated nanowire in response to the excitation light.
