Ion-imprinted MnO₂/CoFe₂O₄ Janus magnetic micromotors synthesized by a lotus pollen template for highly selective recognition and capture of Pb(ii) ions

Abstract

Micromotors that combine the merits of micro-devices with specific functions and autonomous motion have numerous applications in environmental remediation. However, their practical application is blocked by low productivity, complex preparation...

Intelligent micro/nanorobots based on biotemplates

“…14B, Han et al developed a novel Janus micromotor based on the combination of ion-imprinted recognition cavities and self-propelling motion for the sensitive recognition and removal of Pb( ii ) ions from water. 90 Ion-imprinted MnO 2 /CoFe 2 O 4 Janus micromotors inherit the porous structure of lotus pollen grains and reveal sensitive recognition and capture for Pb( ii ) ions and magnetic recovery capability. This study provides a new strategy for the highly selective removal of metal contaminating ions from water.…”

Construction of Sustainable Biomass Bubble Propulsion Micromotor and Selective Recognition/Separation of Shikimic Acid with Open 3D Target Imprinting Cavity

“…8,9 Thus far, researchers have been devoted to exploring alternatives to traditional noble metals as a catalytic medium, and manganese-based substances (MnO 2 , Mn 3 O 4 ) that prompt the decomposition of H 2 O 2 to generate O 2 have attracted a lot of attention because of the merits of abundant resources, low cost, simple preparation, and high catalytic activity. 10,11 Furthermore, the decomposition of H 2 O 2 leaves only green O 2 and H 2 O in the surrounding environment, facilitating the application of manganese-based nano/micromotors in the separation field. On the one hand, the adsorbent material can significantly increase the contact with the target molecule when moving forward with O 2 propulsion, resulting in the enhancement of the adsorption and separation efficiency.…”
