“…Theoretical aspects have been largely developed and discussed in previous papers. 14,19,20 In summary, the viscoelastic response of an interfacial film submitted to a dilatational mechanical strain was studied using a theoretical approach based on two-dimensional rheology. 21 This approach consists of realizing two types of continuous and monotonic compression of the equilibrated surface layer of a pendant drop: a slow compression and fast compression.…”

We have studied the formation of water-CO(2) interfaces in the presence of different concentrations of ovalbumin (OVA) by tensiometry and by means of interfacial rheological measurements to obtain some information on the capacity of protein film to stabilize H(2)O in CO(2) emulsion. The formation of pure water-CO(2) interface can be described as a two-step phenomenon.(1) The CO(2) molecules adsorb onto the water surface and then a reorganization of the interface creates a H(2)O-CO(2) cluster network. This organization occurs at a temperature (40 degrees C) higher than the higher temperature limit (10 degrees C) allowing the formation of crystalline structure called CO(2) clathrate.(2) Our results show that ovalbumin adsorption from bulk concentrations higher than 0.0229 g/L inhibits the cluster formation for a CO(2) pressure less than 80 bar. However, for lower concentrations, the more the CO(2) pressure is close to 80 bar, the more OVA adsorption is reduced by the H(2)O-CO(2) cluster network. Moreover, from a pressure of 90 bar, the affinity of OVA for the interface increases and mixed films made of protein molecules and clusters are obtained for the OVA concentrations lower than 1 g/L.

“…Imparting more hydrophilicity on PLLA and PLLA/CHAp microsphere surface may benefit the cell attachment. The mechanism of PVA binding has been proposed to be due to the interpenetration of PVA and PLLA molecules during microspheres formulation (Boury, Ivanova et al 1995;Sahoo, Panyam et al 2002). The hydrophobic segments of PVA penetrate into the oil phase and remain entrapped into the polymeric matrix of the microspheres.…”

This study demonstrates the potential of confocal laser scanning microscopy (CLSM) as a characterization tool for different types of microparticles. Microparticles were prepared by various methods including complex coacervation, spray drying, double emulsion solvent evaporation technique, and ionotropic gelation. Protein drugs and particle wall polymers were covalently labeled with a fluorescent marker prior to particle preparation, while low molecular weight drugs were labeled by mixing with a fluorescent marker of similar solubility properties. As was demonstrated in several examples, CLSM allowed visualization of the polymeric particle wall composition and detection of heterogeneous polymer distribution or changes in polymer matrix composition under the influence of the drug. Furthermore, CLSM provides a method for threedimensional reconstruction and image analysis of the microparticles by imaging several coplanar sections throughout the object. In conclusion, CLSM allows the inspection of internal particle structures without prior sample destruction. It can be used to localize the encapsulated compounds and to detect special structural details of the particle wall composition.
