“…In recent years, deoxyribonucleic acid (DNA) and cetyltrimethyl-ammonium chloride-modified DNA (DNA-CTMA) biopolymers, which are naturally abundant and biodegradable, have been applied in various research fields in physics, chemistry, and biology. Because of the significant and unique characteristics of DNA molecules, such as high transparency [1], thermal stability [2], nonlinear optical activity [3][4][5], amplified emission [6][7][8], electron blocking, hole transport nature [9][10][11], enhanced fluorescence [12], hosting of laser dyes [13][14][15], and modification capability [16], they can be used in efficient devices and sensors. By embedding specific nanomaterials, such as dye molecules, metal ions, nanoparticles, proteins, and drugs, into the DNA duplexes, functionalized DNA molecules can improve electrical, magnetic, and optical properties as well as biological capabilities [17][18][19][20][21][22][23][24][25].…”

Although the preparation of DNA thin films with well-defined thicknesses controlled by simple physical parameters is crucial for constructing efficient, stable, and reliable DNAbased optoelectronic devices and sensors, it has not been comprehensively studied yet. Here, we construct DNA and surfactant-modified DNA thin films by drop-casting and spin-coating techniques. The DNA thin films formed with different control parameters, such as dropvolume and spin-speed at given DNA concentrations, exhibit characteristic thickness, surface roughness, surface potential, and absorbance, which are measured by a field emission scanning electron microscope, a surface profilometer, an ellipsometer, an atomic force microscope, a Kelvin probe force microscope, and an UV-visible spectroscope. From the observations, we realized that thickness significantly affects the physical properties of DNA thin films. This comprehensive study of thickness-dependent characteristics of DNA and surfactantmodified DNA thin films provides insight into the choice of fabrication techniques in order for the DNA thin films to have desired physical characteristics in further applications, such as optoelectronic devices and sensors.

“…A stable luminophore improves lasing gain and photonic device stability 10 , 34 – the performance and life time of the device are determined by the non-degradation and photostability of the material. Although a photonic device comprising a Rhodamine-6G-doped DNA complex showed amplified spontaneous emission 35 , replacement of a stable and highly sensitive QD luminophore with DNA might increase the device life time and performance further, facilitating their use in biophotonics.…”

To be useful in optoelectronic devices and sensors, a platform comprising stable fluorescence materials is essential. Here we constructed quantum dots (QDs) embedded DNA thin films which aims for stable fluorescence through the stabilization of QDs in the high aspect ratio salmon DNA (SDNA) matrix. Also for maximum luminescence, different concentration and configurations of core- and core/alloy/shell-type QDs were embedded within SDNA. The QD-SDNA thin films were constructed by drop-casting and investigated their optoelectronic properties. The infrared, UV-visible and photoluminescence (PL) spectroscopies confirm the embedment of QDs in the SDNA matrix. Absolute PL quantum yield of the QD-SDNA thin film shows the ~70% boost due to SDNA matrix compared to QDs alone in aqueous phase. The linear increase of PL photon counts from few to order of 5 while increasing [QD] reveals the non-aggregation of QDs within SDNA matrix. These systematic studies on the QD structure, absorbance, and concentration- and thickness-dependent optoelectronic characteristics demonstrate the novel properties of the QD-SDNA thin film. Consequently, the SDNA thin films were suggested to utilize for the generalised optical environments, which has the potential as a matrix for light conversion and harvesting nano-bio material as well as for super resolution bioimaging- and biophotonics-based sensors.

“…The threshold of ASE is also comparable to standard polymers, such asPMMA, or even lower. Recently it has been shown that theDNA-CTMA complex can be successfully doped with standard laser dyes such asrhodamine 6G, sulforhodamine and DCM, but also with more exotic luminescent dyes such asDCNP, BPF, PicoGreen, photochromic spiropyran and hemicyanine [84][85][86][87][88][89][90][91][92][93][94]. The photochromism of hemicyanine can be applied to switching the ASE efficiency by using thesecond and third harmonics of light generated by aNd:YAG pulse laser separately or simultaneously.…”

Biologically produced or inspired materials can serve as optical gain media, i.e. they can exhibit the phenomenon of light amplification. Some of these materials, under suitable dye-doping and optical pumping conditions, show lasing phenomena. The emerging branch of research focused on obtaining lasing action in highly disordered and highly light scattering materials, i.e. research on random lasing, is perfectly suited for biological materials. The use of biomaterials in light amplification has been extensively reported in the literature. In this review we attempt to report on progress in the development of biologically derived systems able to show the phenomena of light amplification and random lasing together with the contribution of our group to this field. The rich world of biopolymers modified with molecular aggregates and nanocrystals, and self-organized at the nanoscale, offers a multitude of possibilities for tailoring luminescent and light scattering properties that are not easily replicated in conventional organic or inorganic materials. Of particular importance and interest are light amplification and lasing, or random lasing studies in biological cells and tissues. In this review we will describe nucleic acids and their complexes employed as gain media due to their favorable optical properties and ease of manipulation. We will report on research conducted on various biomaterials showing structural analogy to nucleic acids such as fluorescent proteins, gelatins in which the first distributed feedback laser was realized, and also amyloids or silks, which, due to their dye-doped fiber-like structure, allow for light amplification. Other materials that were investigated in that respect include polysaccharides, like starch exhibiting favorable photostability in comparison to other biomaterials, and chitosan, which forms photonic crystals or cellulose. Light amplification and random lasing was not only observed in processed biomaterials but also in living cells and tissues or separated phase systems like phosphatydylcholine liposomes. All of the above-mentioned light amplification possibilities of biomaterials also have potential for several interesting applications in biology, medicine, sensing and imaging, which will be described and discussed in this review.
