“…In line with this study, we found here that FeHAs, similarly to undoped non-magnetic CaPs, possess good biocompatibility with cardiac cells and internalize through a clathrin/dynamin-mediated process. The use of low invasive external EMFs for the manipulation of MNPs as well as for field-controlled drug delivery and release applications is nowadays an important topic [7,15,20,40]. One of the most common strategies to activate drug release by alternating EMF, mainly in cancer therapy, consists of the embedding of MNPs in thermo-responsive polymers [8,41].…”

Alternative drug delivery approaches to treat cardiovascular diseases are currently under intense investigation. In this domain, the possibility to target the heart and tailor the amount of drug dose by using a combination of magnetic nanoparticles (NPs) and electromagnetic devices is a fascinating approach. Here, an electromagnetic device based on Helmholtz coils was generated for the application of low-frequency magnetic stimulations to manage drug release from biocompatible superparamagnetic Fe-hydroxyapatite NPs (FeHAs). Integrated with a fluidic circuit mimicking the flow of the cardiovascular environment, the device was efficient to trigger the release of a model drug (ibuprofen) from FeHAs as a function of the applied frequencies. Furthermore, the biological effects on the cardiac system of the identified electromagnetic exposure were assessed in vitro and in vivo by acute stimulation of isolated adult cardiomyocytes and in an animal model. The cardio-compatibility of FeHAs was also assessed in vitro and in an animal model. No alterations of cardiac electrophysiological properties were observed in both cases, providing the evidence that the combination of low-frequency magnetic stimulations and FeHAs might represent a promising strategy for controlled drug delivery to the failing heart.

“…In addition to pressure sensors based on structural materials, strain sensors with high sensitivity to physical strains are another significant family in mechanosensing. − Until now, various strategies, including dimensional changes, − piezoresistivity, − and the tunneling effect, − have been utilized to achieve strain sensors with excellent properties. Recently, spatial separation of conductive elements in conductors, which usually comprise structural nanomaterials, was utilized to realize a highly sensitive strain sensor.…”

Exciting advancements have been made in the field of flexible electronic devices in the last two decades and will certainly lead to a revolution in peoples' lives in the future. However, because of the poor sustainability of the active materials in complex stress environments, new requirements have been adopted for the construction of flexible devices. Thus, hierarchical architectures in natural materials, which have developed various environment-adapted structures and materials through natural selection, can serve as guides to solve the limitations of materials and engineering techniques. This review covers the smart designs of structural materials inspired by natural materials and their utility in the construction of flexible devices. First, we summarize structural materials that accommodate mechanical deformations, which is the fundamental requirement for flexible devices to work properly in complex environments. Second, we discuss the functionalities of flexible devices induced by nature-inspired structural materials, including mechanical sensing, energy harvesting, physically interacting, and so on. Finally, we provide a perspective on newly developed structural materials and their potential applications in future flexible devices, as well as frontier strategies for biomimetic functions. These analyses and summaries are valuable for a systematic understanding of structural materials in electronic devices and will serve as inspirations for smart designs in flexible electronics.

“…The surface of the graphene is very sensitive to strain. 17 Although the lattice mismatch between the cobalt and the graphene is small, it can induce some strains to the graphene surface observable in the Raman measurement. The saturation of the disorder above 1nm thickness of the Co film could be an indication of continuity of Co above 1 nm where the sputtering damage is fully blocked by previously deposited material.…”

Growth of thin cobalt film with perpendicular magnetic anisotropy has been investigated on pristine graphene for spin logic and memory applications. By reduction of the kinetic energy of the sputtered atoms using indirect sputtered deposition, deposition induced defects in the graphene layer have been controlled. Cobalt film on graphene with perpendicular magnetic anisotropy has been developed. Raman spectroscopy of the graphene surface shows very little disorder induced in the graphene by the sputtering process. In addition, upon increasing the cobalt film thickness, the disorder density increases on the graphene and saturates for thicknesses of Co layers above 1 nm. The AFM image indicates a surface roughness of about 0.86 nm. In addition, the deposited film forms a granular structure with a grain size of about 40 nm.
