Figure 8.
The fluorescence images of TRA-imprinted artificial antibody for targeting and labeling the CTCs in mimetic CTCs model. (a–d) nuclear staining with Hoechst, respectively; (e–h) artificial antibody-loaded cells, respectively; (i–l) merged image of (a,e,b,f,c,g,d,h), respectively. Four sets of parallel experiments were employed. The white blood cells are marked in red circles. The concentration of the artificial antibody is 10 μg/mL.
