a Exosomes detection using Au/Ag/silica shell nanorods and magnetic nanoparticles coupled to specific antibodies and SERS measurement. b Circulating cancers cells (CTCs) are detected by magnetic Fe3O4-silicon nanoparticles conjugated to a specific aptamer. The detection was achieved by FITC/FA-labeled BSA. c MiRNA is detected by hybridization to both DNA-conjugated gold and magnetic nanoparticles, while Au concentration is measured by inductively coupled plasma mass spectrometry, after magnetic isolation.
