Title
(EN) FABRICATING CALCITE NANOFLUIDIC CHANNELS
(FR) FABRICATION DE CANAUX NANOFLUIDIQUES EN CALCITE
Abstract
(EN)
A method for fabricating calcite channels in a nanofluidic device is described. A porous membrane is attached to a substrate. Calcite is deposited in porous openings in the porous membrane attached to the substrate. A width of openings in the deposited calcite is in a range from 50 to 100 nanometers (nm). The porous membrane is etched to remove the porous membrane from the substrate to form a fabricated calcite channel structure. Each channel has a width in the range from 50 to 100 nm.
(FR)
La présente invention concerne un procédé pour fabriquer des canaux en calcite dans un dispositif nanofluidique. Une membrane poreuse est fixée à un substrat. De la calcite est déposée dans des ouvertures poreuses dans la membrane poreuse fixée au substrat. Une largeur d'ouvertures dans la calcite déposée est comprise entre 50 et 100 nanomètres (nm). La membrane poreuse est gravée pour retirer la membrane poreuse du substrat pour former une structure de canal de calcite fabriquée. Chaque canal a une largeur dans la plage de 50 à 100 nm.
