“…In the last decade, DNA/RNA molecules have been used as programmable soft materials, and have contributed to the construction of elaborate nano/micrometer-sized selfassembled systems such as 2D/3D nanostructures 92 94 , molecular robots 95,96 , molecular computing devices 97 100 , etc. Programmability of DNA/RNA can be achieved by base sequence design, and the stability of internal and hybridized structures of DNA/RNA molecules can be predicted by thermodynamic calculation of base pairing hydrogen bonding .…”

“…Recently, molecular devices fabricated by taking advantage of DNA base sequences have been much investigated, because molecular programming can be performed by utilizing DNA [11][12][13][14][15][16]. With DNA base sequences, 2D and 3D DNA nanostructures in solution based on rigid motifs including several DNA junctions and building blocks can be designed.…”

This review introduces the self-oscillating behavior of two types of nonthermoresponsive polymer systems with Ru catalyst moieties for the BelousovZhabotinsky (BZ) reaction: one with a poly-vinylpyrrolidone (PVP) main chain, and the other with a poly(2-propenamide) (polyacrylamide) (PAM) main chain. The amplitude of the VP-based self-oscillating polymer chain and the activation energy for self-oscillation are hardly affected by the initial concentrations of the BZ substrates. The influences of the initial concentrations of the BZ substrates and the temperature on the period of the swelling-deswelling self-oscillation are examined in detail. Logarithmic plots of the period against the initial concentration of one BZ substrate, when the concentrations of the other two BZ substrates are fixed, show good linear relationships. The period of the swellingdeswelling self-oscillation decreases with increasing temperature, in accordance with the Arrhenius equation. The maximum frequency (0.5 Hz) of the poly(VP-co-Ru(bpy) 3 ) gel is 20 times that of the poly(NIPAAm-co-Ru(bpy) 3 ) gel. It is also demonstrated that the amplitude of the volume self-oscillation for the gel has a tradeoff with the self-oscillation period. In addition, this review reports the self-oscillating behavior of an AM-based self-oscillating polymer chain as compared to that of the VP-based polymer chain.

Abstract. We will begin with a simplified view of systems biology and synthetic biology. Systems biology extracts information from life, while synthetic biology converts information to reality. This cycle allows the coevolution of life and information, and accelerates the evolution of both. Additionally, the field of molecular robotics has recently emerged. This field is attempting to implement artificial life using biological molecules. We foresee that molecular robots will interface information and life, and the distinction among information, life and artificial life will eventually become a blur. Once molecular robots gain the ability to evolve, then co-evolution of the three will lead to a new stage of intelligence.
