Anticancer effects in monolayer HCT116 colon cancer cells observed by field emission scanning electron microscopy (FE-SEM). The cells were treated with 200 µL of HAPs and HAP-Ps and select nanoformulations. Cells were incubated for 72 h. Untreated cells were used as controls and visualized at different magnifications, from 5 to 25 KX. Scale bar = 1 and 2 µm in control cells. Treated cells were visualized at a magnification of 5KX. Scale bar = 2 µm.
