(a) Fluorescence microscopy images of Hoechst 33342 staining cell nucleus, DiO staining cell membrane, and merged images of Hoechst 33342 and DiO for the captured 5-8F cells on the PLL-coated sintered SiO2 beads, PDA@SiO2 beads, and C@SiO2 beads, respectively. The insert bar is 500 μm. (b) Different exposure-time-obtained fluorescence signal-to-noise ratios between Hoechst 33342 staining cell nucleus (i), DiO staining cell membrane (ii), and merged images of Hoechst 33342 and DiO (iii) of the captured 5-8F cells with the PLL-coated sintered SiO2 beads, PDA@SiO2 beads, and C@SiO2 beads, respectively.
