Graphene oxide, graphdyine and black-phosphorus coated micromotors integrating "three engines" for motion control using different stimuli such as chemical fuel, light, magnetic fields are described. Micromotors can be mass-produced by wrapping gold-sputtered polystyrene microspheres with the 2D nanomaterials, followed simultaneous assembly of Pt or MnO2 nanoparticles (NPs) bubble (catalytic)-engines, Fe2O3 NPs engines, quantum dots (QDs) light engines. The design composition key to get...
Abstract 2D layered molybdenum disulfide (MoS 2 ) nanomaterials are a promising platform for biomedical applications, particularly due to its high biocompatibility characteristics, mechanical and electrical properties, flexible functionalization. Additionally, the bandgap of MoS can be engineered absorb light over wide range wavelengths, which then transformed into local heat applications in photothermal tissue ablation regeneration. However, limitations such as poor stability aqueous...
WS2/Pt and MoS2/Pt bubble propelled micromotors are used as "on-the-fly" sensing platforms in bioassays, using a highly selective affinity peptide probe for "OFF-ON" detection of Escherichia coli model endotoxin.

Propulsion at the microscale has attracted significant research interest. In this work, a numerical simulation to explain speed boost of up 34 % experienced by transition metal dichalcogenides (TMD) based micromotors under effect applied magnetic fields is described. The simulations show that, when an external field applied, flow regime changes from turbulent laminar. This causes increase in residence time fuel over catalyst surface, which enhances oxygen production. more efficient...

Abstract Graphdiyne (GDY), a new kind of two‐dimensional (2D) material, was combined with micromotor technology for “on‐the‐fly” operations in complex biomedia.
