Introduction Nanotechnology is the creation and utilization of materials, devices and systems through the control of the properties and structure of matter at the nanometric scale. Nanobiotechnology is a new and exciting field of research, in which recent advances in nanotechnology are integrated into the biology realm, in particular into molecular biology and cell biology. ‘Nano’ usually refer...

Recently, biochemical systems have been shown to possess interesting computational properties. In a parallel development, the chemical computation metaphor is becoming more and more frequently used as part of the emergent computation paradigm in Computer Science. We review in this contribution the idea behind the chemical computational metaphor and outline its relevance for nanotechnology. We s...

Self-assembly and aggregation of guanine rich sequences can provide useful insights into DNA nanotechnology and telomeric structure and function. In this paper, we designed a guanine rich sequence d(GGCGTTTTGCGG). We found that it can form stable structure in appropriate condition and it exhibits an anomalous CD spectra. This structures can be imaged in ambient environment with a Nanoscope III ...

With the rapid development of nanotechnology in the recent decade, novel DNA and RNA delivery systems for gene therapy have become available that can be used instead of viral vectors. These non-viral vectors can be made of a variety of materials, including inorganic nanoparticles, carbon nanotubes, liposomes, protein and peptide-based nanoparticles, as well as nanoscale polymeric materials. The...

DNA origami represents a class of highly programmable macromolecules that can go through conformational changes in response to external signals. Here we show that a two-dimensional origami rectangle can be effectively folded into a short, cylindrical tube by connecting the two opposite edges through the hybridization of linker strands and that this process can be efficiently reversed via toehol...

Like DNA, RNA can be designed and manipulated to produce a variety of different nanostructures. Moreover, RNA has a flexible structure and possesses catalytic functions that are similar to proteins. Although RNA nanotechnology resembles DNA nanotechnology in many ways, the base-pairing rules for constructing nanoparticles are different. The large variety of loops and motifs found in RNA allows ...

Nanotechnology is the most promising technology field in 21st century, providing benefits and scientific advances to global development. New nanotechnological devices, platforms, production systems have shown a wide range of applicability, especially for nanoparticle applied microorganism detection/diagnosis, treatment, drug delivery. This review aims point main area through several publication...

DNA nanotechnology is a rapidly-growing field, with many potential applications in nanoscale manufacturing and autonomous in vivo diagnostic and therapeutic devices. As experimental techniques improve it will become increasingly important to develop software tools and programming abstractions, to enable rapid and correct design of increasingly sophisticated computational circuits. This is analo...

Journal of Futures Studies, February 2008, 12(3): 71 82 The realm of nanotechnology is in its pioneering stage, similar to what quantum science was in the 1920's and 1930's (Atkinson, 2005, p.34). Like our scientific discoveries of the atom, nuclear fission, DNA, space travel, and the human genome, science has extended human consciousness, enabling humans to ponder in new ways their relationshi...

Branched DNA constructs have found wide application in DNA based nanotechnology. Several reports describe the generation of branched DNA structures with variable numbers of arms to self assemble with pre designed architectures. Branched DNA is generated by using designed rigid crossover DNA molecules as building blocks. Alternatively, branched DNAs can also be generated by using synthetic branc...
