This paper proposes and evaluates link fracturing as an approach for error tolerance in self-assembly by utilizing a DNA chain as a link between two blocks of molecules. Through the use of restriction enzymes, link fracturing breaks the connecting DNA chain between two blocks if an incorrect assembly has occurred due to the erroneous growth of tiles. Two error tolerant techniques are proposed by fracturing...
This paper presents a study of errors that occur in DNA self-assembly using synthesized tile sets for template manufacturing. It is shown that due to the reduced size, aggregates assembled by a synthesized tile set are not error-free as those assembled by maximum-sized (referred to as a trivial tile set) as well asnon-synthesized tile sets. Compared with non-synthesized tile sets, aggregates assembled...
Error detection/correction techniques have been advocated for algorithmic self-assembly. Under rectilinear growth, it requires only two additional tiles, generally referred to as Isolation tiles. This process can be effectively utilized for checkpointing and is analyzed in this paper self-assembly. Initially, the physical framework (and related features) for the removal of the erroneous sections of...
This paper proposes the control of monomer concentration as a novel improvement of the kinetic tile assembly model (kTAM) to reduce the error rate in DNA self-assembly. Tolerance to errors in this process is very important for manufacturing highly dense ICs; the proposed technique significantly decreases error rates (i.e. it increases error tolerance) by controlling the concentration of monomers....
