Abstract:
A method of assembly of micro-scale objects includes forming a pattern of a first functional moiety on a surface of a substrate, contacting the surface of the substrate with a first liquid suspension including first micro-scale feedstock elements functionalized with a second functional moiety, complimentary to the first functional moiety, on first portions of the first micro-scale feedstock elements and functionalized with a third functional moiety on second portions of the first micro-scale feedstock elements, aligning the first portions of the first micro-scale feedstock elements with the surface of the substrate, and facilitating bonding the second functional moieties to the first functional moieties to form a first microstructure pattern of the first micro-scale feedstock elements on the surface of the substrate.
Abstract:
A mold for casting a micro-scale dry adhesive structure includes an upper surface including a first cavity having a first depth, a negative pattern for an array of micro-scale structures defined in a surface of the first cavity, and at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures, the at least one second cavity defining a negative pattern for a standoff of the micro-scale dry adhesive structure.
