444 | HA@Fe3O4@SiO2 | Colorimetric determination of tumor cells | tumor cell | Color | In the presence of HeLa cells, the visible region absorbance sharply decreased up to the cell concentration of 0.25 × 106 cells/mL, with both nanozymes (Fig. 9A). In the concentration range of 0.25–4.0 × 106 cells/mL, the visible region absorbance linearly decreased with the increasing cell concentration, with satisfactorily high correlation coefficients for both nanozymes. However, a sharper linear decrease with almost 1.6 times higher slope was observed with HA@Fe3O4@SiO2 microspheres with respect to Fe3O4@SiO2 microspheres with HeLa cells. | |||||
