Bioinspired 3D hierarchical BSA-NiCo2O4@MnO2/C multifunctional micromotors for simultaneous spectrophotometric determination of enzyme activity and pollutant removal

Motion-based phenol detection and degradation using 3D hierarchical AA-NiMn-CLDHs@HNTs-Ag nanomotors

“…To explore the possible reactive oxygen species (ROS) in the nanomotors + H 2 O 2 + 4-AAP + phenol system, isopropanol (IPA), N 2 and NaN 3 were introduced into the reaction systems as scavengers 46 to capture ˙OH, O 2 ˙ − and 1 O 2 , respectively. As shown in Fig.…”

Smart micro- and nanorobots for water purification

“…For example, Pt-covered pollen grains remove Hg 2+ in H 2 O 2 with a remarkable efficiency (∼80% in 2 h) 145 . As an alternative to membrane-assisted electrodeposition, kapok fibres can be used as a sacrificial template on which to prepare bubble-propelled tubular microrobots for Cu 2+ removal 146 . Similarly, spirulina, an edible alga, has been employed as a scaffold on which to fabricate magnetically actuated microrobots, owing to its peculiar helical structure 147 .…”

Biomass-derived 3D hierarchical Zr-based tubular magnetomotors with peroxidase-like properties for selective colorimetric detection and specific decontamination of glyphosate at neutral pH

“…Our group synthesized several novel multifunctional micromotors with hierarchical structures for the determination and removal of multiple pollutants from wastewater. 31–35 These reports have demonstrated the positive effect of the self-propulsion of dynamic moving devices on the enhancement of detection and isolation performance, especially for the removal of trace contaminants. Joseph Wang and his group reported self-propelled zirconia-based tubular micromotors for powerful capture and isolation of hazardous nerve agents.…”
