“…As a result, there is no non-linear effect in the electrical signal as we checked, which occurs, by contrast, in DNA-gold composite. 17 We have confirmed that the I-V of our gold-coated DNA-composited fiber is linear, which is important for appropriately applying the TET technique.…”

“…Only a few have recently began to study the thermal conduction in DNA. The thermal conductivity of a DNA-gold composite has been measured to be 150 W/m · K, 17 comparable to 317 W/m · K for the thermal conductivity of pure gold at 300 K. 18 In contrast, a Peyrard-Bishop-Dauxois (PBD) modeling result suggests that the thermal conductivity of the DNA double helix is 1.8 × 10 −3 W/m · K, 19 and a 3-D coarse-grained modeling estimates that the thermal conductivity of a uniform (polyG-polyC) DNA is no more than 0.3 W/m · K. 20 Both modeling results indicate that the DNA molecule is a poor heat conductor with a low thermal conductivity. However, it is still a mystery whether the DNA molecule is a good heat conductor or insulator experimentally, as is the thermal conduction mechanism along DNA chain bases, which needs to be figured out entirely.…”

Simple convergent-nozzle aerosol injector for single-particle diffractive imaging with X-ray free-electron lasers Structural Dynamics 2, 041717 (2015) This work reports on the synthesis of crystalline DNA-composited films and microfibers, and details the study of thermal energy transport in them. The transient electro-thermal technique is used to characterize the thermal transport in DNA composite microfibers, and the photothermal technique is used to explore the thermal transport in the thickness direction of DNA films. Compared with microfibers, the DNA films are found to have a higher thermal transport capacity, largely due to the carefully controlled crystallization process in film synthesis. In high NaCl concentration solutions, the bond of the Na + ion and phosphate group aligns the DNA molecules with the NaCl crystal structure during crystallization. This results in significant enhancement of thermal transport in the DNA films with aligned structure. C 2014 Author(s

“…The thermal conductivity of DNA and DNA-CTMA measured 0.82 W/mK and 0.6 W/mK, respectively. Compared with the thermal conductivity of PMMA, 0.12 W/mK, reported in the literature (11) , we find that the thermal conductivity of DNA is 7X higher than the thermal conductivity of PMMA and the thermal conductivity of DNA-CTMA is 5 times higher. This suggests that if DNA is introduced into the device, the potential exists for removing heat from the device more efficiently than using other polymer materials.…”

In this paper, a logic computing model was constructed using a DNA nanoparticle, combined with color change technology of DNA/Au nanoparticle conjugates, and DNA computing. Several important technologies are utilized in this molecular computing model: DNA self-assembly, DNA/Au nanoparticle conjugation, and the color change resulting from Au nanoparticle aggregation. The simple logic computing model was realized by a color change, resulting from changing of DNA self-assembly. Based on this computing model, a set of operations computing model was also established, by which a simple logic problem was solved. To enlarge the applications of this logic nanocomputing system, a molecular detection method was developed for H1N1 virus gene detection. In the area of computing research, molecular computing has gradually grown from pure theory to experimental realization. In particular, DNA computing has become a leader in molecular computing, because of its advantages in nanotechnology operations. At the beginning of DNA computing, scientists attempted to solve certain difficult mathematical problems, such as the satisfiability problem, the graph coloring problem, the maximal clique problem, and the maximum independent set problem [1][2][3][4]. Despite the difficulty in comparing DNA computing, with traditional electronic computing, its potential in huge parallel computing remains an attractive focus. In the area of information science, logic computing is a basic unit of computing. Thus, it is important to utilize molecules to implement logic computing, in which the molecules play a significant role. Many kinds of materials could be used to construct to logic gates, such as nucleic acids, and enzymes [5][6][7][8][9][10][11]. Logic systems based on DNA have attracted the most attention [12][13][14][15]. Recently, the combination of DNA self-assembly and nanoparticles has become a research hot spot [16][17][18][19]. A nanoparticle is a type of tiny particle at the nanometers scale. Commonly used nanoparticles are Au, Ag, and semi-conductor quantum dots. Importantly, the most widely used is the gold nanoparticle (AuNP), which is stable, uniform, and has strong chemical binding ability.In this paper, a logic computing model was constructed using DNA nanoparticles, combined with the color change technology of the DNA/Au nanoparticle conjugates and DNA computing.
