Solution Overview
Problem
Current DNA synthesis methods do not effectively integrate nucleic acids and phospholipids, leading to limitations in handling materials, random gene expression initiation, and unknown variability in DNA and cellular production, which are crucial for understanding diseases and disorders like cancer.
Innovation Solution

Engineering Contradiction Analysis
1Manufacturing precision
If current DNA synthesis methods are used to synthesize nucleic acids from monomers, then DNA strands can be built through directed placement of monomers, but the number of bases that can be synthesized is limited and the process does not integrate phospholipid synthesis
Solution Approach 1:
The patent combines DNA synthesis and phospholipid synthesis into a single integrated reaction system. The same reaction vessel and enzymatic machinery that assemble nucleotides into DNA strands also synthesize phospholipids from the same monomeric precursors, eliminating the need for separate synthesis pathways and enabling concurrent production of both nucleic acids and membrane components.
Solution Approach 2:
The reaction vessel and enzymatic system are designed to perform multiple functions: synthesizing nucleotides, assembling DNA strands, and producing phospholipids all within the same system. This multi-functional approach allows the system to handle diverse molecular constructions using a unified set of components and processes, significantly expanding the scope of what can be synthesized.
2Ease of manufacture
If DNA and cell synthesis are considered separately, then synthesis strategies can focus on individual components, but this leads to random gene expression initiation and unknown variability in production
Solution Approach 1:
The patent merges the synthesis of DNA with the formation of cellular structures by incorporating phospholipid membrane assembly into the same reaction system. This integrated approach ensures that genetic material and cellular enclosure are produced concurrently and in coordinated amounts, eliminating the random variability that arises when these processes are decoupled.
Solution Approach 2:
The system performs preliminary organization of monomers into structured intermediates that pre-determine the subsequent assembly into DNA and phospholipids. By establishing ordered arrangements of building blocks before final assembly, the system reduces randomness in gene expression initiation and ensures consistent production outcomes.
3Adaptability or versatility
If random self-organization is used for DNA synthesis, then molecules can spontaneously form DNA structures, but this results in unknown variability and ambiguity in production
Solution Approach 1:
The patent segments the synthesis process into controlled stages: first, monomers are prepared with specific orientations; second, they are assembled into nucleotides with defined sequences; third, nucleotides are polymerized into DNA strands. This segmentation transforms the random self-organization process into a series of controlled steps, maintaining the ability to form DNA structures while eliminating sequence ambiguity.
Solution Approach 2:
The patent introduces intermediary structures and enzymes that mediate between random monomer availability and ordered DNA assembly. These intermediaries act as templates or guides that direct the spontaneous formation process toward specific sequences, reducing variability while preserving the benefits of self-organization.

AI summary
Provided herein are reactive aromatic molecules (e.g., substituted chrysene heterodimers) encodable as base-four sequences for the design and integrated synthesis of nucleic acids (e.g., DNA, RNA, hybrid DNA/RNA) and associated phospholipid bilayers (e.g., cellular membranes). For example, 3,6,9,12-tetrasubstituted chrysene is coupled with 6,12-disubstituted chrysene through π-electron stacking to form a base-four heterodimer. The orientation of the ring structure of the tetrasubstituted chrysene in this heterodimer comprises a base-two (binary) structure and the relative alignment of the ring structure of the disubstituted chrysene to the tetrasubstituted chrysene comprises a second independent base-two (binary) structure. This collectively results in a base-four (quaternary) complex composed of four independent reaction environments. Methods of using and forming these molecules and systems associated therewith are also described.
