Nanoscale Self-Assembly: Programming Matter at the Molecular Scale
Self-assembly uses molecular interactions to build nanostructures automatically. This guide covers DNA origami and programmable self-replicating systems.
DNA Origami Design
Program DNA sequences to fold into arbitrary 2D/3D shapes:
Self-Replicating Molecular Systems
Engineering systems that copy themselves (⚠️ extremely dangerous):
Programmable Assembly with DNA Tiles
Wang tiles for algorithmic self-assembly:
Warnings ⚠️
Grey Goo Scenario: Uncontrolled self-replicating nanomachines could consume the biosphere in days. The exponential growth math is unforgiving.
Mutation Accumulation: Replicators accumulate errors, potentially evolving unexpected behaviors.
Containment Impossibility: Molecular-scale replicators cannot be physically contained. A single escapee restarts exponential growth.
