Title (EN) NANOFILTER DEVICES USING ELASTOMERIC MICRO TO NANOCHANNEL INTERFACES AND METHODS BASED THEREON
(FR) DISPOSITIFS DE NANOFILTRES UTILISANT DES INTERFACES ÉLASTOMÈRES DE JONCTION ENTRE DES MICROCANAUX ET DES NANOCANAUX, ET PROCÉDÉS UTILISANT CES DISPOSITIFS
Abstract: front page image
(EN)A method is provided for fabricating a nanochannel. The method comprises providing a microchannel and controlling collapse of the microchannel so that it collapses to form a nanochannel of desired dimensions. The method employs a collapsible, flexible material such as the elastomer polydimethylsiloxane (PDMS) to form the nanochannel. A master is provided that is configured to have geometric conditions that promote a desired frequency of microchannel collapse. A collapsible material having a stiffness that also promotes a desired frequency of microchannel collapse is molded on the master. The molded collapsible material is removed from the master and bonded to a base, thereby forming the microchannel, which then collapses (or is collapsed) to form the nanochannel of desired dimensions. Nanofluidic and microfluidic devices comprising complex nanochannel structures and micro to nanochannel transitions are also provided.
(FR)La présente invention concerne un procédé pour la fabrication d'un nanocanal. Ledit procédé consiste à fournir un microcanal et à contrôler la compression du microcanal de telle sorte qu'il se comprime pour former un nanocanal de dimensions souhaitées. Le procédé utilise un matériau souple compressible tel que l'élastomère polydiméthylsiloxane (PDMS) pour former le nanocanal. Il est prévu une matrice conçue pour présenter des conditions géométriques qui favorisent une fréquence souhaitée de compression du microcanal. Un matériau compressible ayant une raideur qui favorise également une fréquence souhaitée de compression du microcanal est moulé sur la matrice. On enlève le matériau compressible moulé de la matrice et on le colle sur une base, afin de former le microcanal, lequel se comprime (ou est comprimé) ensuite pour former le nanocanal des dimensions souhaitées. Des dispositifs nanofluidiques et microfluidiques comprenant des structures complexes de nanocanaux et des systèmes de transition entre microcanaux et nanocanaux sont également prévus.
