Glycine concentration in halite crystals (wt%) as a function of the growth duration (days) for crystals grown from 67 mM (blue diamonds) and 133 mM (dark gray squares) glycine–NaCl solutions. All data points represent triplicate averages; 2σ errors are smaller than the symbol size. Shaded regions denote two crystallization regimes: rapid, inclusion-rich hopper growth during the first ∼10 days, and slower, more ordered growth with reduced inclusion incorporation thereafter.
