“…It is worth mentioning that the potential interaction between magnetic materials and light within magnetic fields, such as the magneto‐optical effect, optical signals, particularly polarized ones may undergo distortions. [ 119,120 ] The AMN systems in general are relatively less susceptible to magneto‐optical effects. It remains a concern worthy of consideration in future developments due to the inherent interaction of light with magnetic materials.…”

Magnetically responsive optical modulation has emerged as a promising application in various fields such as smart windows, anti‐counterfeiting, and colorimetric sensors, due to its unique advantages in remote and nondestructive control, as well as precise and high‐contrast response. Compared to isotropic counterparts, anisotropic magnetic nanostructures (AMNs) take advantage of the interplay among magnetic dipoles, magnetocrystalline anisotropy, shape anisotropy, and crystal facets to control diverse dimensions of light propagation. By manipulating frequency, amplitude, polarization, and plasmonic resonance, AMNs can provide a variety of functional applications. A comprehensive overview of recent developments in optical modulation based on AMNs with a focus on their emerging applications and design strategies is presented. It starts with a brief introduction of typical AMN building blocks, highlighting various optical modulation modes, including tunable transmission, diffraction, polarization, and plasmonic resonance. The primary focus is to discuss design strategies for various applications, i.e., smart windows, anti‐counterfeiting labels, colorimetric sensors, and multifunctional‐driven devices. It concludes with the challenges and perspectives for magneto‐optical modulation based on anisotropic structures. Overall, this review provides in‐depth insight into building blocks, magnetic modulation strategies, and optical property modulation of AMNs, thereby accelerating practical applications of these structures in functional devices.

“…The utilization of magneto-optic modalities presents two primary effects contributing to the generation of electricity for illuminating light sources: the piezoelectric effect and the magnetostrictive effect [268,269] (Figure 10d). The piezoelectric effect occurs within specific materials like piezoelectric ceramics and polymers, including ferroelectrics.…”

Optogenetic modulation of brain neural activity that combines optical and electrical modes in a unitary neural system has recently gained robust momentum. Controlling illumination spatial coverage, designing light‐activated modulators, and developing wireless light delivery and data transmission are crucial for maximizing the use of optical neuromodulation. To this end, biocompatible electrodes with enhanced optoelectrical performance, device integration for multiplexed addressing, wireless transmission, and multimodal operation in soft systems have been developed. This review provides an outlook for uniformly illuminating large brain areas while spatiotemporally imaging the neural responses upon optoelectrical stimulation with little artifacts. Representative concepts and important breakthroughs, such as head‐mounted illumination, multiple implanted optical fibers, and micro‐light‐delivery devices, are discussed. Examples of techniques that incorporate electrophysiological monitoring and optoelectrical stimulation are presented. Challenges and perspectives are posed for further research efforts toward high‐density optoelectrical neural interface modulation, with the potential for nonpharmacological neurological disease treatments and wireless optoelectrical stimulation.

Repair of large bone defects caused by trauma or disease poses significant clinical challenges. Extensive research has focused on metallic materials for bone repair because of their favorable mechanical properties, biocompatibility, and manufacturing processes. Traditional metallic materials, such as stainless steel and titanium alloys, are widely used in clinics. Biodegradable metallic materials, such as iron, magnesium, and zinc alloys, are promising candidates for bone repair because of their ability to degrade over time. Emerging metallic materials, such as porous tantalum and bismuth alloys, have gained attention as bone implants owing to their bone affinity and multifunctionality. However, these metallic materials encounter many practical difficulties that require urgent improvement. In this article, we systematically reviewed and analyzed the metallic materials used for bone repair, providing a comprehensive overview of their morphology, mechanical properties, biocompatibility, and in vivo implantation. Furthermore, we summarized the strategies and efforts made to address the short‐comings of metallic materials. Finally, we identified and discussed perspectives for the development of metallic materials to guide future research and advancements in clinical practice.This article is protected by copyright.
