"It has been argued that a central objective of nanotechnology is to make \nproducts inexpensively, and that self-replication is an effective approach \nto very low-cost manufacturing. The research presented here is intended to \nbe a step towards this vision. We describe a computational simulation of \nnanoscale machines floating in a virtual liquid. The machines can bond \ntogether to form strands (chains) that self-replicate and self-assemble \ninto user-specified meshes. There are four types of machines and the \nsequence of machine types in a strand determines the shape of the mesh \nthey will build. A strand may be in an unfolded state, in which the bonds \nare straight, or in a folded state, in which the bond angles depend on the \ntypes of machines. By choosing the sequence of machine types in a strand, \nthe user can specify a variety of polygonal shapes. A simulation typically \nbegins with an initial unfolded seed strand in a soup of unbonded machines. \nThe seed strand replicates by bonding with free machines in the soup. The \nchild strands fold into the encoded polygonal shape, and then the polygons \ndrift together and bond to form a mesh. We demonstrate that a variety of \npolygonal meshes can be manufactured in the simulation, by simply changing \nthe sequence of machine types in the seed."^^ . "2006-07" . . "12" . "3" . .
