The following experiment is conducted to And out the pH at which the polymer will precipitate, and induce drug release from the liposomes, once anchored on the membrane. The phase transition pH is determined at 37°C by measuring the turbidity of the polymer solutions at different pHs. As the polymer undergoes coil-to-globule transition and aggregates, the turbidity of the polymer solution increases. 

In several recent publications, Peden and coworkers inferred that pentacoordinated aluminum ions, which are clearly visible in Al NMR spectra ofY-Al203, determine most of the surface and bulk chemistry of this material. The authors proposed pentacoordinated aluminum ions to act as structural promoters for phase transitions (150), for anchoring of platinum oxide (332), as well as for the sintering of supported platinum metal particles (333). The authors supported their conclusion with calculations based on the nonspinel structural model of Y-AI2O3 by Digne et al. (158) the results indicated that pentacoordinated aluminum adsorption sites may be located on the (100) face. The same group used the (100) and (110) faces of this nonspinel-type structure to model the adsorption of NO (334).
