Figure 4From: A Nanodot Array Modulates Cell Adhesion and Induces an Apoptosis-Like Abnormality in NIH-3T3 CellsSEM images of the used nanodot arrays. Nanodot arrays of 100-nm and 200-nm were cleaned and washed thoroughly after culturing cells. SEM images were taken on the cleaned nanodot arrays of (a,b) 100-nm and (c,d) 200-nmBack to article page
