“…The fluorescence intensity of the Alq 3 molecules is uniform along the longitudinal axis of particles doped with DNA (Fig. 1b ) while that of the sides of particles is slightly higher due to the optical waveguide effects of crystals toward the edges 16 , 29 , 30 . The fluorescence intensity of the Alq 3 molecules on the center of particles doped with DNA-Cy3 becomes lower (Fig.…”

“…However, compared to fluorescent enhancement, optical waveguide phenomena reveal similar loss coefficient values for T 20 and A 20 and G 20 and C 20 . For the optical waveguide phenomena, light propagation is mainly affected by the surface of the Alq 3 crystal 16 , whereas PL enhancement after treatment with complementary DNAs originates from the surface and inner core of the Alq 3 particles. The molecular distribution of doped DNA with different base moieties at the Alq 3 surface is shown in Supplementary Fig.…”

“…The unique physical and chemical properties make nucleic acid-associated materials the focus of numerous studies. For example, a nucleic acid molecule is generally complexed with π-conjugated organic semiconductors and serves as (i) an efficient receptor element for recognizing biological/chemical targets 5 – 7 , (ii) a template for the assembly and polymerization of organic semiconductors 8 – 10 , (iii) a walking component in a light-driven artificial nanomachine 11 , 12 , (iv) a wide-bandgap material in organic light-emitting diodes enhancing their luminescence efficiency 2 , 13 , 14 , (v) a molecular gadget for tuning organic semiconductor crystals bio-active when properly hybridized 15 , and (vi) a biological moiety of organic hybrid crystals for remote sensing via optical waveguide effects 16 .…”

Molecular doping of nucleic acids into light emitting crystals driven by multisite-intermolecular interaction

We reveal the fundamental understanding of molecular doping of DNAs into organic semiconducting tris (8-hydroxyquinoline) aluminum (Alq3) crystals by varying types and numbers of purines and pyrimidines constituting DNA. Electrostatic, hydrogen bonding, and π-π stacking interactions between Alq3 and DNAs are the major factors affecting the molecular doping. Longer DNAs induce a higher degree of doping due to electrostatic interactions between phosphate backbone and Alq3. Among four bases, single thymine bases induce the multisite interactions of π-π stacking and hydrogen bonding with single Alq3, occurring within a probability of 4.37%. In contrast, single adenine bases form multisite interactions, within lower probability (1.93%), with two-neighboring Alq3. These multisite interactions facilitate the molecular doping into Alq3 particles compared to cytosines or guanines only forming π-π stacking. Thus, photoluminescence and optical waveguide phenomena of crystals were successfully tailored. This discovery should deepen our fundamental understanding of incorporating DNAs into organic semiconducting crystals.

“…The application of light-harnessing approaches has been extended to flexible strain sensors, [126] optoelectronic devices, [127] diffraction gratings, [128] and biophotonic sensors. [129] In this regard, various types of optical sensing strategies were introduced based on different substrates (e.g., PDMS) fabrication methods (e.g., nanostructured wrinkles), and light-harnessing mechanisms (surface plasmon polariton (SPP), localized surface plasmon resonance (LSPR), and infrared (IR)). [128] In one study, using the multispectral capabilities, Xu et al [49] developed an adaptive camouflage platform inspired by wrinkled cephalopods (Figure 13a).…”

“…DNA‐lipid complexes have widely been studied for their excellent optical properties, in particular their optical transparency. [ 14a,89 ] Similarly to silk fibroin and cellulose‐based films, DNA‐lipid complexes are excellent host materials for optical dyes. Interestingly, DNAs, as well as the DNA‐based phosphors, are very promising optical materials for bio hybrid LEDs to realize eco‐friendly and rare‐earth phosphor‐free LEDs.…”

side effects such as air pollution, climate change, declines in natural resources, and technological inequality. The new responsibility of scientists and engineers is to develop a new sustainable technology that is sustainable and that does not further deplete the planet's natural resources. Specifically, silicon-based electronics and optoelectronic devices have short lifespans. For example, the average lifespans for mobile phones and laptops are less than four years on average, [1] and some sensing devices have even shorter lifespans, generating waste after a short time period. Therefore, environmental issues, such as the depletion of scarce resources and production of toxic byproducts, became an area of increased concern. Technological advances in photonics and electronics, in particular, are now facing the issue of depletion of oil, the foremost source of organic materials. The generation of chemical and inorganic wastes during the process of photonic and electronic device production is also a pressing problem. In addition, costly devices may increase the inequality gap between developed and developing countries, which is a pressing problem, particularly in the area of medical applications. Therefore, it is an essential task for researchers to investigate potential material candidates that are readily degradable without any harmful byproducts, and that are also abundant in nature, thus reducing their cost. Many materials of biological origin have been investigated with the goal of achieving sustainable technology so far. In this review, we summarize recent technological achievements based on the most widely investigated materials: silk and paper. Silk, which was initially deployed mainly for the clothing industry, is a natural eco-friendly material with unique properties. Due to its exceptional characteristics of being fully biodegradable and eliciting no immune response, silk has now become one of the most promising materials for biomedical applications such as biomedical implantable devices. Together with excellent optical transparency in the visible range of light, the exceptional biocompatibility of silk has inspired many outstanding developments of optical devices for biomedical sensing applications. Silk has also attracted attention for its use in electronic devices. It has been shown that silk is particularly beneficial for organic thin-film transistors (OTFTs) applications as it can improve the crystal quality of organic semiconductors. There has also been much interesting research done on silk-based transient electronic devices and carbonized silk-based electrical sensors. [2] Meanwhile, paper, one of the oldest and most familiar bio-based materials in human history, has also shown its advantages of outstanding optical and mechanical properties with the promise Photonic and electronic devices currently face challenges in terms of improved efficiency of energy harvesting and light emission, renewable energy and materials, and the development of eco-friendly materials. Owing to the emergence of worldwid...
