Abstract:
The present invention relates generally to molecular printing techniques for use in sensors, arrays, and integrated optics and electronics. The invention features described give rise to the ability to immobilize biological probes by force-induced patterning, while still maintaining the conductivity of the graphene substrate. Most particularly, the present invention relates to covalent patterning of graphene surface using a force-accelerated reaction.
Abstract:
Improved methods of forming a patterned self-assembled monolayer on a surface and derivative articles are provided. According to one method, an elastomeric stamp is deformed during and/or prior to using the stamp to print a self-assembled molecular monolayer on a surface. According to another method, during monolayer printing the surface is contacted with a liquid that is immiscible with the molecular monolayer-forming species to effect controlled reactive spreading of the monolayer on the surface. Methods of printing self-assembled molecular monolayers on nonplanar surfaces and derivative articles are provided, as are methods of etching surfaces patterned with self-assembled monolayers, including methods of etching silicon. Optical elements including flexible diffraction gratings, mirrors, and lenses are provided, as are methods for forming optical devices and other articles using lithographic molding. A method for controlling the shape of a liquid on the surface of an article is provided, involving applying the liquid to a self-assembled monolayer on the surface, and controlling the electrical potential of the surface.
Abstract:
The invention relates to a method for transferring a nano-layer (1) from a first substrate (5, 105) to a second substrate (30, 130), wherein the nano-layer (1) comprises a self-aggregating monolayer with cross-linked phenyl units and/or a mono-atomic graphite layer (graphene), wherein the method comprises the following steps: a. applying a transfer medium (20, 120) onto nano-layer (1), wherein in this step or afterwards the transfer medium (20, 120) is transformed from a liquid or gaseous phase in a solid phase; b. separating the transfer medium (20, 120) and the nano-layer (1) from the first substrate (5, 105); and c. applying the transfer medium (20, 120) and the nano-layer (1) onto the second substrate (30, 130); and d. removing the transfer medium (20, 120).
Abstract:
A method for controllably forming zinc oxide nanostructures on a surface via an organic template, which is formed using a stamp prepared from pre-defined relief structures, inking the stamp with a solution comprising self-assembled monolayer (SAM) molecules, contacting the stamp to the surface, such as Ag sputtered on Si, and immersing the surface with the patterned SAM molecules with a zinc-containing solution with pH control to form zinc oxide nanostructures on the bare Ag surface.
Abstract:
A deformable stamp for patterning a surface. The stamp can be placed in contact with an entire 3-dimensional object, such as a rod, in a single step. The stamp can also be used to pattern the inside of a tube or rolled over a surface to form a continuous pattern. The stamp may also be used for fluidic patterning by flowing material through channels defined by raised and recessed portions in the surface of the stamp as it contacts the substrate. The stamp may be used to deposit self-assembled monolayers, biological materials, metals, polymers, ceramics, or a variety of other materials. The patterned substrates may be used in a variety of engineering and medical applications.
Abstract:
An automated process for microcontact printing is provided, comprising the steps of providing a substrate and a stamp; automatically aligning the substrate and stamp so that the stamp is aligned relative to the substrate to impart a pattern to the substrate at a desired location and with a desired orientation on the substrate; applying an ink to the stamp, the ink including a molecular species adapted to form a self-assembling monolayer (SAM) on the substrate; contacting the stamp and the substrate; and separating the stamp from the substrate.
