The shape of the pressure traces in Fig. suggest that alginate deposition occurs faster with high concentration solutions than at low concentrations. That is, the slope of ∆P (t) during deposition is steeper for higher concentration conditions. Further, fitting ∆P (t) to a diffusively driven deposition model allows estimation of deposition efficiency as a function of system parameters . A larger percentage of the flowing alginate gel deposits at higher concentrations of components. However, deposition is less efficient at low concentrations. Because high component concentrations are associated with stiffer gels, it follows that stiffer gels deposit more efficiently.
