Abstract
The present invention is related to an electrochemical reactor (1) and a microfluidic platform (20) comprising this reactor (1), controlling pH in a closed environment, wherein this reactor (1) comprises at least one cell (2), wherein each cell (2) containing at least one micro-well (3a) able to contain a liquid and reagents and a cap (7) to close the said cell (2) and wherein the cell (2) further comprises at least one working electrode (5) producing reversible REDOX reactions.
Claims21
An electrochemical reactor controlling pH over at least one pH unit, in a closed environment, said reactor comprising:
- one or more cell(s), each cell containing two connected micro-wells separated by a diffusion barrier, wherein the first micro-well comprises a working electrode functionalized with reversible REDOX molecules deposited upon the working electrode and the second micro-well comprising a counter electrode,
- a cap which is configured to open and close said cell and
- a proton membrane covering the working electrode.
An electrochemical reactor controlling pH over at least one pH unit in a closed environment said reactor comprising:
- one or more cell(s) each cell containing two connected micro-wells separated by a diffusion barrier, wherein the first micro-well comprises a working electrode functionalized with reversible REDOX molecules deposited upon the working electrode and the second micro-well comprising a counter electrode, and
- a cap which is configured to open and close said cell
- wherein the cap comprises a flat rigid substrate or semi-rigid substrate, coated with a hydrophobic layer, and wherein the flat rigid substrate or the flat semi-rigid substrate comprises a hydrophilic polyethylene glycol layer and wherein the hydrophobic layer is a self-assembled monolayer of silanes, polymeric organosilicone, or lipidic nanoparticles.
An electrochemical reactor controlling pH over at least one pH unit, in a closed environment, said reactor comprising:
- one or more cell(s), each cell containing two connected micro-wells separated by a diffusion barrier, wherein the first micro-well comprises a working electrode functionalized with reversible REDOX molecules deposited upon the working electrode and the second micro-well comprising a counter electrode, and
- a cap which is configured to open and close said cell
- wherein the cap comprises a flat rigid substrate or semi-rigid substrate, coated with a hydrophobic layer, and wherein the hydrophobic layer is made of one or more layer(s) of colloidal nanoparticles obtained from lipid droplets, further stabilized by a surfactant selected from the group consisting of polyethoxylated surfactant, lecithin, and a mixture thereof.
