The values for the equilibrium constants (K2, K3) were estimated from the relevant Eo values. The simulated voltam-

PVC membrane electrodes that are selective and sensitive to copper(l1) have been developed. The best electrode, based on 13,14-benzo-I ,5-tetrathiacyclopentadecane and 2-nitrophenyl octyl ether solvent mediator w i t h a potassium tetrakis(p-chloropheny1)borate anion excluder, exhibits a linear response in the range 10-1-10-6 M over the pH range 2.9-6.7 and has a Nernstian slope of 28-29 m V per decade at 25 "C. The response time is 10 s.

Coordination polymer (CP) nanoparticles (NPs) formed by a self-assembly of organic ligands and metal ions are one of the attractive materials for molecular capture and deliver/release in aqueous media. Control of particle size and prevention of aggregation among CP NPs are important factors for improving their adsorption capability in water. We demonstrate here the potential of a liposome incorporating an antibiotic ion channel as a vessel for synthesizing Prussian blue (PB) NPs, being a typical CP. In the formation of PB NPs within liposomes, the influx rate of Fe ions into liposome encapsulated [Fe(CN)] through channels was fundamental for the change of NPs' sizes. The optimized PB NP-liposome composite showed higher adsorption capacity of Cs ions than that of aggregated PB NPs that are prepared without liposome in aqueous media.

The synthesis of a luminescent coordination polymer (Tb-BTC) within the confined environment of a liposome allowed for the anisotropic growth of nanosized Tb-BTC crystals. Consequently, the resulting composite Tb-BTC@Lipo exhibited a higher fluorescence sensitivity to fluoride anions in aqueous media compared to the independent Tb-BTC in bulk.

CREB dysfunction, mediated by PKA and iPLA2 suppression, may be involved in the deteriorated liver regeneration in the cirrhotic rats.
