Low magnification transmission electron microscopy (TEM, Philips CM120) image of the synthesized (a) NPsmall, (e) NPbig&thin, and (i) NPbig&thick; Optical absorption spectra taken from (b) NPsmall, (f) NPbig&thin, and (j) NPbig&thick; Hour-by-hour MB release profiles of (c) NPsmall, (g) NPbig&thin, and (k) NPbig&thick, and cumulative MB release profiles of (d) NPsmall, (h) NPbig&thin, and (l) NPbig&thick from deionized water at 37 °C; Morphological evolution of the NPs by TEM after being immersed in deionized water at 37 °C for (m) 1, (n) 4, (o) 8 and (p) 14 days, and Panc-1 cell at 37 °C for (q) 12, (r) 24, (s) 60 and (t) 74 h. All scale bars were at 100 nm
