Figure Lengend Snippet: ( A ) Enzymatic degradation observed under the time-lapse DIC imaging in the presence of trypsin enzyme at a concentration comparable to the pancreatic juice at 37°C. ( B ) An increase in the dimensions of albumin microswimmers during the degradation before the total collapse of the microswimmer fabric. ( C and D ) The biocompatibility of the degradation products of albumin microswimmers assessed by the viability of the exposed haMSCs at 24 hours. (C) Representative calcein acetoxymethyl ester/ethidium homodimer-1–stained fluorescence images of the exposed haMSCs. (D) The viability of the exposed haMSCs assessed based on the quantified intracellular adenosine 5′-triphosphate amount.
Article Snippet: We generated a double-helix microswimmer array printed with varying laser intensities in the range of 7.78 × 10 13 to 1.21 × 10 14 W cm −2 ( ).
