(a) Synthesis route of mP3/4HB-acrylate and its preparation of mP3/4HB-g-bPEI copolymer by Michael addition. Confocal microscopy images of the A549 cell uptake of (b) free siRNA and (c) P3/4HB-g-bPEI/siRNA complexes. (d) Lipofectamine and (e) bPEI were employed as the control. Cy3-labeled siRNA appeared red fluorescence and the cell nuclei were stained blue using DAPI. Adapted with permission from reference 53 (2012 Elsevier).
