“…In this case, DNA aptamers have an specific structure that binds specifically to the surface of malignant-type cells and, after laser irradiation, strong photothermal and drug delivery, a synergistic anti-cancer effect is observed [ 216 ]. On the other hand, another recent application is in the production of thin films of DNA and CTMA embedded with gold nanorods that were characterized by measurements of photoluminescence, X-ray photoelectron spectroscopy and ultraviolet-visible (UV-Vis) spectroscopy [ 217 ]. These films had potential applications for filters, blocking layers and biosensors, among others.…”

“…Other sources of genomic DNA, such as calf-thymus and salmon (with an average size ∼50 Kbp), have also been used for 1D DNA-templated structures [ 361 , 362 ]. Materials such as nanorod-DNA thin films and DNA-CTMA fibers were fabricated with salmon DNA, providing advantages in the selectivity of dimensionality, solubility in organic and inorganic solvents, and functionality enhancement [ 217 ]. Furthermore, salmon DNA was used in the assembly of films with optoelectronic characteristics and made of synthetic double-crossover (DX) DNA lattices and the doping of double divalent metal ions [ 363 ].…”

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.

“…Deoxyribonucleic acid (DNA) has been the primary material of interest due to its distinct properties, including high dielectric constant, large bandgap and high transparency. Pristine DNA(D) and cetyltrimethylammonium chloride (CTMA) surfactant-modified DNA (CD) can extend utility in inorganic-and organic-based devices and sensor applications [6][7][8][9][10]. Furthermore, DNA can be utilized as an efficient template for hosting drugs, dyes, ions and nanoparticles for enhancing functionality [11][12][13][14][15].…”

The development of flexible DNA thin films embedded with diverse functional nanomaterials might be beneficial for electronic devices and biosensors. In this work, we fabricated two different methods of electrodes (i.e., metal paste spotted electrodes and metal layer electrodes) on flexible drug- and dye-embedded DNA thin films to examine the electrical and capacitance properties for conduction and energy storage, respectively. Enhanced current and reduced capacitance of drug-embedded DNA thin films compared to pristine DNA with Ag paste electrodes were observed due to the intrinsic characteristics of the drugs. We introduced the e-beam deposition process for fabricating relatively large area metal (such as Au and Al) coated electrodes, which ensures the creation of metal layers on both sides of the flexible thin films while improving metal contact. There was a significant current increase in DNA thin films with metal layer electrodes compared to DNA thin films with Ag paste electrodes. Furthermore, capacitances measured from Au/Dg/Au and Al/Dg/Al capacitors were relatively more stable than Ag paste DNA thin films. The physical properties of our samples might easily be controlled by manipulating functional nanomaterials in DNA thin films and various types of metal layer electrodes. Our self-supporting DNA thin films with integrated nanomaterials and durable metal layer electrodes might be employed in flexible electronic devices such as nanogenerators, skin electronics, and biosensors in the future.

Nucleic acids are widely recognized as the most evolved information processing soft material, possessing intrinsic efficiency in transferring and harvesting photon, electron, and energy. Recent developments in semiconductor synthetic biology and nanophotonics have spurred significant research efforts toward modifying and modulating nucleic acid assemblies. Given the rapid advances in using carbon-based hybrid materials for renewable energy, information technology–biotechnology fusion, and medicine, this review highlights recent research on nucleic acid-assembled hybrid materials, their design rationale, and performance modulation according to various application scenarios. Bridging the gap between molecular functionalization and material engineering, this review aims to provide a systematic analysis for researchers, engineers, and end-users to make informed decisions promptly.
