Synthesis of dual function Fe₃O₄@MnO₂@HKUST-1 magnetic micromotors for efficient colorimetric detection and degradation of hydroquinone

Abstract

Herein, we demonstrated a novel Fe3O4@MnO2@HKUST-1 magnetic micromotors with excellent peroxidase-like activity for highly efficient colorimetric detection and degradation of hydroquinone. Such micromotors had unique flower-like morphology with high exposed...

Nano/Micromotors for Cancer Diagnosis and Therapy: Innovative Designs to Improve Biocompatibility

“…When using nano/micromotors for cancer treatment, the disadvantage of traditional chemical propulsion modes is the unavoidable use of toxic fuel, which hinders their future in vivo application [ 16 , 19 ]. The use of natural enzymes for catalytic bubble production [ 20 , 21 ] and magnetic fields [ 22 , 23 ], ultrasound waves [ 24 , 25 ], or light [ 26 , 27 ] shows great promise in providing a biocompatible method for nano/micromotor propulsion. Another major factor that leads to biotoxicity may be the materials used to produce nano/micromotors.…”
