“…Detailed reviews of applications based on flexible 2D materials are given in some papers that recently appeared in the literature. [228][229][230][231][232] In the following, we briefly review some of those applications where the mechanical and optical properties of the employed materials (i.e., TMDs) enable new opportunities. As a first example, TMDs have been found to be among the most promising 2D materials for skin-mountable electronics because of their high flexibility, robustness, and moderate bandgap energy (in the range of 1.1-2.5 eV), which provides unique optical and electrical property combinations that are hardly found even in the archetypal 2D material, graphene.…”

[ 226 ] Ideal materials for skin‐mountable devices need to have a high flexibility—besides an accurate mechanical design of the device itself—to be fabricated and operated on unusual substrates like skin, as well as for achieving good sensing capabilities and stable device operation under high‐strain conditions.…”

While static methods are often essential to make a material suited to a specific application, by permanently altering its properties, dynamic ones potentially enable their real-time modulation, paving the way for the development of reconfigurable devices.Within this context, strain engineering has historically been regarded as a "static" tuning method, which exploited the crystal deformations induced by the juxtaposition of materials with different lattice constants to manipulate the properties of semiconductor heterostructures [1] and improve the performance of electronic devices (e.g., CMOS-based logic technologies [2] ). In recent years, however, strain-engineering paradigms have begun to shift, leading to the development of new devices, capable of generating a dynamic modulation of the mechanical deformations induced in the active materials (and, thus, of their optoelectronic properties).Micro-and nano-electromechanical systems (MEMS and NEMS), for example, have long been used for sensing applications, thanks to their ability to transduce external stresses (e.g., applied pressure/weights, molecule adsorption,...) into electrical signals. In the opposite regime they are, at least in principle, 2D materials, such as graphene, hexagonal boron nitride (hBN), and transition-metal dichalcogenides (TMDs), are intrinsically flexible, can withstand very large strains (>10% lattice deformations), and their optoelectronic properties display a clear and distinctive response to an applied stress. As such, they are uniquely positioned both for the investigation of the effects of mechanical deformations on solid-state systems and for the exploitation of these effects in innovative devices. For example, 2D materials can be easily employed to transduce nanometric mechanical deformations into, e.g., clearly detectable electrical signals, thus enabling the fabrication of high-performance sensors; just as easily, however, external stresses can be used as a "knob" to dynamically control the properties of 2D materials, thereby leading to the realization of strain-tuneable, fully reconfigurable devices. Here, the main methods are reviewed to induce and characterize, at the nm level, mechanical deformations in 2D materials. After presenting the latest results concerning the mechanical, elastic, and adhesive properties of these unique systems, one of their most promising applications is briefly discussed: the realization of nano-electromechanical systems based on vibrating 2D membranes, potentially capable of operating at high frequencies (>100 MHz) and over a large dynamic range.The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/admi.202102220.

Carbon Nanomaterials (CNMs) and Enzymes: From Nanozymes to CNM-Enzyme Conjugates and Biodegradation

Carbon nanomaterials (CNMs) and enzymes differ significantly in terms of their physico-chemical properties—their handling and characterization require very different specialized skills. Therefore, their combination is not trivial. Numerous studies exist at the interface between these two components—especially in the area of sensing—but also involving biofuel cells, biocatalysis, and even biomedical applications including innovative therapeutic approaches and theranostics. Finally, enzymes that are capable of biodegrading CNMs have been identified, and they may play an important role in controlling the environmental fate of these structures after their use. CNMs’ widespread use has created more and more opportunities for their entry into the environment, and thus it becomes increasingly important to understand how to biodegrade them. In this concise review, we will cover the progress made in the last five years on this exciting topic, focusing on the applications, and concluding with future perspectives on research combining carbon nanomaterials and enzymes.
