Normalized photofluorescence from CT26 mucin cells treated with chemical endocytosis inhibitors for 1 h and incubated with 50 μg/mL a bare core-shell NPs and b nanobody-tagged NPs at 37 °C in 5% CO2 for 30 min. Inhibitors with a statistical effect on the internalization (Student’s t test, p (*) < 0.05 and p (**) < 0.01) are marked with black asterisks
