DNA-based membranes for potential applications

Nile red and Nile blue are highly fluorescent and photostable organic dyes from the benzo[a]phenoxazine family. They have been used as histological stains for imaging lysosomes and lipids in vitro. The dyes' high quantum yields and solvent-dependent optical properties make them ideal scaffolds for the development of pH probes and local polarity indicators. Reviews of the literature in this area are scarce with only one review ever published in 2006. It has been 10 years since and the field has evolved. This review aims to expand upon topics covered by the previous reviewers and to report on recent advances in the literature. As authors, we hope to convey a sense of scope and to spark renewed interest in this useful niche of dye chemistry.

“…As consequence, the presence of some dyes in DNA leads to already colored membranes. However, the ECD with WO 3 /DNA-NB/CeO 2 -TiO 2 configuration is different of other ECDs because it starts to display a transmittance difference at about 700 nm, which in the range of 780 to 1100 nm is about 16% between color and bleached states [44]. Finally, comparing the transmittance results of ECDs with DNA-CTMA-PEDOT and DNA-PEDOT electrolytes one can observe a slightly larger difference in transmittance between the colored and the bleached states in the case of ECD with DNA-PEDOT membrane.…”

Natural macromolecules are very promising row materials to be used in modern technology including security and defense. They are abundant in nature, easy to extract and possess biocompatibility and biodegradability properties. These materials can be modified throughout chemical or physical processes, and can be doped with lithium and rare earth salts, ionic liquids, organic and inorganic acids. In this communication samples of DNA and modified DNA were doped with Prussian Blue (PB), poly(ethylene dioxythiophene) (PEDOT), europium and erbium triflate and organic dyes such as Nile Blue (NB), Disperse Red 1 (DR1) and Disperse Orange 3 (DO3). The colored or colorless membranes were characterized by electrochemical and spectroscopic measurements, and they were applied in electrochromic devices (ECDs) and dye sensitized solar cells (DSSC). ECDs change the color under applied potential, so they can modulate the intensity of transmitted light of 15 to 35%. As the electrochromic materials, WO 3 or Prussian blue (PB), are usually blue colored, the color change is from transparent to blue. DNA, and the complexes: DNA-CTMA, DNA-DODA and DNA-PEDOT:PSS were also investigated as either hole carrier material (HTM) or polymer electrolyte in dye-sensitized solar cells (DSSC). The DNA-based samples as HTM in small DSSCs revealed a solar energy conversion efficiency of 0.56%. Polymer electrolytes of DNA-CTMA and DNA-DODA, both with 10 wt% of LiI/I 2 , applied in small DSSC, exhibited the efficiencies of 0.18 and 0.66%, respectively. The obtained results show that natural macromolecules-based membranes are not only environmentally friendly but are also promising materials to be investigated for several electrochemical devices. However, to obtain better performances more research is still needed.

“…The vibration of N–H from amide II appeared at 1534 cm –1 . In addition, two strong bands are present at 1230 and 1060 cm –1 ; the first one is attributed to the asymmetric PO 2 – stretching vibration (νPO 2 – asm) and the second corresponds to the symmetric PO 2 – stretching vibration (νPO 2 – sm) , in DNA. Compared to the pristine DNA structure, the peaks of the DCNS/CFC complex presented a light redshift owing to the vibration of the electrons caused by the π–π stacking interactions between the DNA and carbon matrix …”

DNA-Guided Li₂S Nanostructure Deposition for High-Sulfur-Loaded Li–S Batteries

The low areal capacity caused by low sulfur loading (<2.0 mg cm −2 ) and the poor sulfur utilization due to the insulating Li 2 S layer covering the cathode always limit the practical applications of lithium−sulfur batteries (Li−S batteries). Deoxyribonucleic acid (DNA)-controlled nucleation and growth of Li 2 S in the Li−S system were first studied in this work. The negatively charged sugar-phosphate backbone of DNA could attract Li + ions and allow crystalline Li 2 S to grow along the DNA chains. The electrodeposition of Li 2 S with a unique three-dimensional nanostructure during the polysulfide conversion and deposition process was realized, which can not only boost electron and ion transport but also expose and retain more active sites in the cathode. A Li−S battery with ultrahigh sulfur loading of 10 mg cm −2 and a low electrolyte/sulfur ratio of 6.08 delivered a high areal capacity of 8.1 mA h cm −2 , which is more than 2 times that of commercial Li-ion batteries, demonstrating a great enhancement of the Li−S battery compared to other studies. Therefore, this study provides an effective strategy of DNA-guided 3D Li 2 S deposition for achieving high-sulfurloading Li−S batteries.
