Methods of serial assembly of DNA bricks into larger structures
First Claim
1. A method comprising the following steps, in combination:
- (a) attaching a first deoxyribonucleic acid (DNA) brick to a solid substrate in a first fluidic flow;
(b) attaching a second DNA brick to the first DNA brick in a second fluidic flow;
(c) then attaching, to a previous DNA brick, an additional DNA brick in an additional fluidic flow,(d) then repeating step (c) at least one more time; and
(e) removing a structure from the solid substrate, which structure comprises the DNA bricks attached to each other in steps (b), (c) and (d);
wherein(i) the previous DNA brick mentioned in step (c) is (I) in the first iteration of step (c), the second DNA brick, and (II) in each subsequent iteration of step (c) pursuant to step (d), the additional DNA brick attached in the previous iteration of step (c),(ii) the fluidic flows are separate from each other and occur in order in a temporal sequence,(iii) attachments between structural units comprise nucleobase pairing, and(iv) during the temporal sequence, a specific attachment permutation is used repeatedly, in separate fluidic flows which occur at different times, to form multiple attachments between structural units in an assembly sequence.

Abstract
In exemplary implementations of this invention, hierarchical, nanometer-precise assembly is performed: A first structural unit is attached to a solid substrate in a first fluidic flow. A second structural unit is attached to the first structural unit in a second fluidic flow, a third structural unit is attached to the second structural unit in a third fluidic flow, and so on, until a target structure comprising the structural units is assembled. The first, second, third and so on fluidic flows are separate and occur in order in a temporal sequence. During the temporal sequence, a specific permutation of nucleobases is used repeatedly, in separate fluidic flows which occur at different times, to form multiple attachments between structural units in an assembly. The assembled target structure is removed from the solid substrate. Attachments between the structural units may be formed by nucleobase pairing.
