“…The largest values have been obtained very recently by investigating DNA in thin solid films 38 . The values reported for n 2 are in the range 10 −13 –10 −11 cm 2 /W, that is at least three orders of magnitude smaller than the one we report here.…”

Throughout the whole history of liquid crystals science, the balancing of intrinsic elasticity with coupling to external forces has been the key strategy for most application and investigation. While the coupling of the optical field to the nematic director is at the base of a wealth of thoroughly described optical effects, a significant variety of geometries and materials have not been considered yet. Here we show that by adopting a simple cell geometry and measuring the optically induced birefringence, we can readily extract the twist elastic coefficient K22 of thermotropic and lyotropic chiral nematics (N*). The value of K22 we obtain for chiral doped 5CB thermotropic N* well matches those reported in the literature. With this same strategy, we could determine for the first time K22 of the N* phase of concentrated aqueous solutions of DNA oligomers, bypassing the limitations that so far prevented measuring the elastic constants of this class of liquid crystalline materials. The present study also enlightens the significant nonlinear optical response of DNA liquid crystals.

“…Based on these properties, research has developed around exploiting DNA films as optical memory materials and optical amplifiers . For example, DNA films show favorable characteristics as a saturable absorber, a material whose absorbance decreases at higher light power, and as such have been used to passively mode‐lock a fiber laser cavity . Another successful application of DNA films is as an electron blocking layer in organic light‐emitting diodes .…”

Rapid development of DNA technology has provided a feasible route to creating nanoscale materials. DNA acts as a self‐assembled nanoscaffold capable of assuming any three‐dimensional shape. The ability to integrate dyes and new optical materials such as quantum dots and plasmonic nanoparticles precisely onto these architectures provides new ways to exploit their near‐ and far‐field interactions. A fundamental understanding of these optical processes will help drive development of next‐generation photonic nanomaterials. This review is focused on latest progress in DNA‐based photonic materials and highlights DNA scaffolds for rapidly assembling and prototyping nanoscale optical devices. Three areas are discussed including intrinsically active DNA structures displaying chiral properties, DNA scaffolds hosting plasmonic nanomaterials, and fluorophore‐labeled DNAs that engage in Förster resonance energy transfer and give rise to complex molecular photonic wires. An explanation of what is desired from these optical processes when harnessed sets the tone for what DNA scaffolds are providing toward each focus. Examples from the literature illustrate current progress along with a discussion of challenges to overcome for further improvements. Opportunities to integrate diverse classes of optically active molecules including light‐generating enzymes, fluorescent proteins, nanoclusters, and metal–chelates in new structural combinations on DNA scaffolds are also highlighted.

“…shown, from some verses having scientific signs (Chaabani 2006;2013;2018) The structures of DNA and clay minerals were both revealed mainly thanks to X-ray diffraction principle applied according to X-ray crystallography techniques developed particularly from about 1920 to 1953 (e.g., see Watson and Crick 1953;Larson and Wherry 1925;Endell et al 1933). Researchers have continued to investigate the different proprieties of these two elements and their utility until nowadays (e.g., Khazaeinezhad, R. et al 2017, Schakenraad et al 2017Schoonheydt and Johnston 2011;Krupskaya et al 2017).…”

The miraculous dynamism of the Qur’an: An example of a modern reading reveals a DNA designation

The major miracle of the Qur"an would reside in its ability to be virtuous, valid and worthwhile for all humans living at all times and everywhere. Here, I propose three major processes which would provide the basis for this dynamism peculiar to the Qur"an. A detailed example of one of these processes related to the scientific signs is presented. It starts from a verse that can represent a metaphor whereby DNA is designated Salsal (Arabic word refers to the swelling-expanding clay minerals). I have supported this metaphor showing that DNA and swelling-expanding clay minerals have really evident features in common. Moreover I have demonstrated the marvelous analogy that, coupled to this metaphor, permits to test its suitability by specifying that some DNA forms are similar to some potteries. Hence, according to my interpretation, this verse represents a wonderful painting that, elevated to an unusual pinnacle of creation, outlines information at the highest degree of scientific accuracy wearing a dress of superb Arabic rhetorical modes that only the light of knowledge and wisdom can penetrate it. The different research stages on this verse and other related ones show that the dynamic processes in question is not merely a dynamic progressive revelation of scientific signs during successive modern epochs, but also, if deeply analyzed, a dynamic grounding constructive for the scientific research. The present modern reading provides original interpretations based, among other things, on the making and the application of a modern approach that would permit to reach a rigorous academic level in the interpretation of the Qur"an text in general, and the allegorical verses related to scientific subjects in particular. In conclusion, the present research will advance our understanding on the dynamism of the Qur"an that should be shaped and implemented by re-reading Qur"an at all times and everywhere and trying continually to correct previous erroneous interpretations due mainly to a personal and socio-cultural-political influence and/or a limited scientific knowledge of the exegetes at a given epoch.
