Figure 2.

Displacement of magnetic particles within 2 mg/mL and 5 mg/mL collagen hydrogels. Confocal images of 0.5 wt% magnetic particles in 2 mg/mL collagen hydrogels (A) prior to polymerization and (B) post polymerization (20-seconds between images) (n = 115). Fluorescent images of 0.5 wt% magnetic particles in 5 mg/mL collagen hydrogels (C) prior to polymerization and (D) post polymerization, (n = 115). Cyan = without magnetic field, magenta = with magnetic field of 2500-Oe. Scale = 50-μm. (E,F) Quantification of bead displacement in response to a magnetic field in 2 mg/mL and 5 mg/mL collagen hydrogels. (G) Box plots of bead displacement. *p < 0.05
