This work introduces improved performances of self-propelled tubular micromotors based on radio frequency (RF)-rotating plasma-prepared graphene oxide-poly(aniline) (GO-PANI), graphene oxide/poly(ethylaniline) (GO-PEANI), and graphene oxide/poly(fluoroaniline) (GO-PFANI) composites as outer layer and platinum (Pt) as the catalytic inner layer. Scanning electron microscopy energy-dispersive X-ray (SEM-EDX), X-ray diffraction (XRD) analysis, Fourier-transform infrared spectroscopy (FTIR), and electrochemical cyclic voltammetry (CV) techniques were utilized to characterize the RF-rotating plasma-modified graphene oxide-based composites. Incorporating the impressive features of graphene oxide (GO) and PANI or its substitute derivatives, the composite micromotors offer an efficient performance in dye-labeled single-stranded DNA immobilization due to changes in the fluorescence intensity and speed of micromotors.
