We next investigate our control over the deposition/ablation phenomena by adjusting the experimental parameters. We vary the concentration of calcium crosslinker, C Ca 2+ , at fixed concentration of alginate C Alg . We next vary the total gel concentration, C Gel , which is equal to C Alg at a fixed ratio of the calcium crosslinker. Then we vary the flow rates Q T . These variations are captured in each of the three sections of Table .
