“…Moreover, with advances in genomics, proteomics and the new understanding of RNA, nucleic acid-based nanotechnology has been widely studied [ 177 ]. Additionally, nucleobases (the small molecules that constitute DNA and RNA), are useful as moieties for the ecological synthesis of various organic and organic-inorganic materials [ 178 , 179 , 180 ]. In this review we will show some relevant examples of structures and materials with optical properties and metamaterial characteristics made with DNA and RNA.…”

Metamaterials are broadly defined as artificial, electromagnetically homogeneous structures that exhibit unusual physical properties that are not present in nature. They possess extraordinary capabilities to bend electromagnetic waves. Their size, shape and composition can be engineered to modify their characteristics, such as iridescence, color shift, absorbance at different wavelengths, etc., and harness them as biosensors. Metamaterial construction from biological sources such as carbohydrates, proteins and nucleic acids represents a low-cost alternative, rendering high quantities and yields. In addition, the malleability of these biomaterials makes it possible to fabricate an endless number of structured materials such as composited nanoparticles, biofilms, nanofibers, quantum dots, and many others, with very specific, invaluable and tremendously useful optical characteristics. The intrinsic characteristics observed in biomaterials make them suitable for biomedical applications. This review addresses the optical characteristics of metamaterials obtained from the major macromolecules found in nature: carbohydrates, proteins and DNA, highlighting their biosensor field use, and pointing out their physical properties and production paths.

“…In recent decades, cadmium sulfide (CdS) has garnered significant attention in the field of optoelectronics, with applications in quantum dot luminescence, − solar cell power, − lasers cooling, , and photocatalysis. , Particularly, the photocatalytic activation of carbon–hydrogen (C–H) bonds to form carbon–carbon (C–C) bonds enables the rapid diversification of simple and widely available starting materials. This technique is also valuable for modifying complex molecular structures at later stages. , A noteworthy example is the study by Wang et al, which elucidated the mechanism of selective C–H activation through photoexcited holes in CdS nanorods, resulting in the high-efficiency synthesis of ethylene glycol with 90% selectivity .…”

Photoexcitation polarons in semiconductor materials play a crucial role in various fields, such as enhancing electrical conductivity, influencing chemical selectivity, and improving reaction efficiency in semiconductor photocatalysis. To comprehensively understand the properties of polarons, time-resolved mid-infrared, near-infrared, and visible transient absorption spectroscopies were employed to investigate the photogenerated carriers in cadmium sulfide (CdS) single crystals. We have determined the midgap energy levels of defect states by transient infrared absorption-excitation energy scanning spectra. Furthermore, we observed the formation of both the electron and hole polarons, where the electron polarons are coupled to the longitudinal acoustic phonons, while the hole polarons are coupled to both optical and longitudinal acoustic phonons. The photogenerated free electrons were trapped by the S-vacancies at 0.14 eV below the minimum of the conduction band, leading to the formation of electron polarons with a trapping time constant of 4.5 ps, while hole polarons are formed at Cd vacancies located at 0.04 eV above the maximum of the valence band with a time constant of 2.9 ps. Our determined midgap energy levels of the trapped states together with dynamical properties of electron and hole polarons provide insights into optimizing the photocatalytic property of CdS.

“…[26] Despite the promising features of PEDOT:PSS, its high hygroscopicity and acidity, anisotropic charge injection, and batch-to-batch variation in electrical and physical properties are known to limit the large-scale fabrication of PSC modules and compromise the long-term stability of the operational devices. [18] At present, more and more researchers are beginning to realize the fact that the sophisticated device structures with the deposition of multiple interface layers [17,19,33] processed by various conditions and technologies limit their prospects for commercial applications, even though the interface layer has a crucial impact on the overall device performance of PSCs. [16,18,34] More recently, some studies demonstrated the comparable or better photovoltaic performance of devices through the simplifications of device structures and processing techniques.…”

Despite the tremendous development of different high-performing photovoltaic systems in non-fullerene polymer solar cells (PSCs), improving their performance is still highly demanding. Herein, an effective and compatible strategy, i.e., binary-solvent-chlorinated indium tin oxide (ITO) anode, is presented to improve the device performance of the state-of-the-art photoactive systems. Although both ODCB (1,2-dichlorobenzene) solvent-and ODCB:H 2 O 2 (hydrogen peroxide) co-solvent-chlorinated ITO (ITO
