Summary: A single-step electrochemical procedure for synthesizing a brush-like platform and studying its hysteresis properties and electrochemical response is described in this study. It is demonstrated that the direction of the magnetic easy axis of the brush-like architecture can be tailored, and the coercivity and remanence of the magnetic system can be controlled. The presence of an applied magnetic field enhances the electrode charge-transfer response of the Ni nanobrush, which is attributed to a larger electroactive area.

Summary: 2D layered molybdenum disulfide (MoS2) nanomaterials show high biocompatibility, mechanical and electrical properties, and flexible functionalization for biomedical applications. However, poor stability of aqueous dispersions and low accumulation in affected tissues limit their potential. In this study, multifunctional MoS2-based magnetic helical microrobots (MoSBOTs) using cyanobacterium Spirulina platensis are proposed for therapeutic and biorecognition applications. These cytocompatible microrobots combine remote magnetic navigation with MoS2 photothermal activity, enabling targeted photothermal ablation and on-the-fly biorecognition in minimally invasive cancer treatment.

Summary: In this study, we describe the light-triggered photophoretic motion of WS2 micromotors. These micromotors were prepared using liquid-phase exfoliation of pristine WS2 in water, resulting in a layered material with high photoconversion capability. Under electromagnetic irradiation, the micromotors exhibit positive photophoretic motion and swarming-like behavior. Computational fluid dynamics simulations were used to characterize the photophoretic propulsion mechanism of the micromotors. These novel micromotors can perform collective motion without the need for surfactants or fuels, reaching velocities of up to 6000 μm/s, making them the fastest light-driven micromotor platform to date with potential for cutting-edge applications.
