Table 1.

IC₂₀ values of QD-encoded microcapsules.

Time interval, h	IC20, microcapsules/cell
24	NA
48	37.4 ± 8.5*
72	44.4 ± 7.4*

The results are mean ± SD for three independent measurements.

^*Non-significant differences between the IC₂₀ values (p > 0.05 according to Student's t-test); NA, data not available; IC₂₀, the concentration of the QD-encoded microcapsules at which the cell viability is 80%.
