Abstract
The precipitation of calcium oxalate monohydrate (COM) at phospholipid monolayers has been observed in-situ by Brewster angle microscopy (BAM). A monolayer of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) compressed to a LC state over a calcium oxalate subphase shows the growth of COM as very bright spots. The identity of COM was confirmed in a transferred film by scanning electron microscopy. BAM can also be used to determine where COM precipitates when the monolayer has two phases at equilibrium. Monolayers of DPPC and 1,2-dipalmitoyl-sn-glycero-3-[phospho-rac-(1-glycerol)] (DPPG) crystallize COM at phase boundaries. In addition, phase separated binary phospholipid mixtures of DPPC and 1,2-dimiristoyl-sn-glycero-3-phosphocholine (DMPC) have been prepared and monitored by BAM. The crystal growth in this case is confined to domains of DPPC due to its ability to form a liquid condensed phase.
