When life gets physical
The subatomic world is nothing like the world that biologists study. Physicists have struggled for almost a century to understand the wave– particle duality of matter and energy, but many questions remain unanswered. That biological systems ultimately obey the rules of quantum mechanics might be self-evident, but the idea that those rules are the very basis of certain biological functions has n...
متن کاملSelf-assembly, modularity, and physical complexity.
We present a quantitative measure of physical complexity, based on the amount of information required to build a given physical structure through self-assembly. Our procedure can be adapted to any given geometry, and thus, to any given type of physical structure that can be divided into building blocks. We illustrate our approach using self-assembling polyominoes, and demonstrate the breadth of...
متن کاملPhysical principles for DNA tile self-assembly.
DNA tiles provide a promising technique for assembling structures with nanoscale resolution through self-assembly by basic interactions rather than top-down assembly of individual structures. Tile systems can be programmed to grow based on logical rules, allowing for a small number of tile types to assemble large, complex assemblies that can retain nanoscale resolution. Such algorithmic systems...
متن کاملChemical synthesis gets a fillip from molecular recognition and self-assembly processes.
By drawing on nature conceptually, the practice of chemical synthesis can now be broadened in scope to include the supramolecular synthesis of supermolecules and their postassembly covalent modification to form mechanically interlocked molecules, which the chemist can use to build functioning nanosystems after the style of those found in the living world.
متن کاملMapping Virtual Self-assembly Rules to Physical Systems
Throughout nature, decentralized components emerge into complex forms. It is through their interaction that components, governed by simple rules, self-assemble to create specific entities. The programs constituting these entities are based on the rules present in a given system and are executed on the physically and chemically encoded information comprising the components and their environment....
