Steam sterilization resistance test of PEEK microcarriers which have been hydrothermal treated at 180°C for 8 h. The micrographs (a), size distribution (b) and SEM images (c) of repeated sterilized microcarriers in an autoclave for 1 time (-1), 2 times (-2) and 3 times (-3). The scale bar lengths for a-1 to a-3 and c-1 to c-3 are 500 and 20 μm, respectively
