bPEI‐AuNPs function as drug carriers and enhance contractility of cardiomyocytes in 3D engineered tissues. a) MUSCLEMOTION‐based quantitative analysis of contractility of engineered cardiac tissues at different days post‐fabrication (n = 3). b) Examples of projections of confocal images of hiPSC‐derived cardiomyocyte‐laden tissue constructs at 7 or 16 days post‐fabrication stained for the cardiomyocyte‐specific marker sarcomeric‐α‐actinin and troponin I. Data are mean ± SD and compared based on a two‐way ANOVA and Bonferroni's multiple comparison test. Scale bars: yellow: 25 µm and white: 4 µm.
