Abstract
Described are methods and devices for forming patterned lipid multilayer structures on a substrate using a topographically structured stamp and a topographically structured brush.
Claims46
A method comprising the following steps:
- (a) printing one or more lipid inks on a substrate using a topographically structured stamp, and
- (b) removing the stamp from the substrate to form a patterned substrate,
- wherein the stamp comprises one or more recesses containing the one or more lipid inks prior to step (a),
- wherein the one or more recesses have one or more recess patterns,
- wherein the patterned substrate comprises one or more patterned arrays of lipid multilayer structures, and
- wherein the patterned arrays are based on the one or more recess patterns.
3 more elements
A device comprising:
- an ink palette on which is positioned one or more lipid inks,
- a stamp having one or more recesses for receiving the one or more lipid inks from the ink palette and printing the one or more lipid inks as patterned lipid multilayer structures on a substrate,
- an ink palette contacting device for causing the stamp to contact the ink palette, and
- a substrate contacting device for causing the stamp to contact the substrate.
1 more element
A method comprising the following step:
- (a) spreading one or more lipid inks on a substrate using an edge of topographically structured brush to thereby form a patterned substrate comprising a patterned array of one or more lipid multilayer structures on the substrate,
- wherein the brush comprises one or more recesses in a surface of the brush including the edge,
- wherein the one or more recesses extend to the edge, and
- wherein the one or more recesses have a recess pattern that shape the one or more lipid inks to form the patterned array of one or more lipid multilayer structures.
1 more element
A device comprising:
- a brush for spreading one or more lipid inks on a substrate to form a patterned substrate comprising a patterned array of one or more lipid multilayer structures on the substrate,
- wherein the brush comprises an edge and one or more recesses in a surface of the brush including the edge,
- wherein the one or more recesses extend to the edge,
- wherein the one or more recesses have a recess pattern that shape the one or more lipid inks to form the patterned array of one or more lipid multilayer structures, and
- wherein the brush is oriented at an angle of less than 90° with respect to a portion of the substrate on which the one or more lipid inks are present.
