(A) Functionalization of micro/nanorobot with different bioreceptors towards biosensing of target analytes, including cells, proteins, and nucleic acids. (B) ssDNA-functionalized microrockets for selective hybridization and isolation of nucleic acids (75). (C) Specific intracellular detection of miRNA in intact cancer cells using ultrasound-propelled nanomotors (80).
