This chapter deals with the layer-by-layer (LbL) assembly of polyelectrolyte multilayers of polypeptides (poly L-ly sine/poly L-glutamic acid) and polysaccharides (chitosan/dextran suliate) onto soft and porous thermo-responsive poly (N-isopropylacrylamide-co-methacrylic acid) (P(NiPAM-co-MAA)) nanogels. The formation of the LbL structures and characterization of hydro-dynamic radius, electrophoretic mobility, bilayer thickness and stability over time of the systems will be comparatively discussed. Further, the assembly of biopolymers onto similar microgels will be analyzed. The results presented demonstrate that the structure and properties of biocompatible multilayer films can be finely tuned by confinement onto soft and porous gels, which provides new perspectives for biomedical plications, particularly storage and controlled release of biomolecules.

Hawkins and Brash investigated some aspects of the biosynthesis of 11R-and 12R-HETE in eggs of S. purpuratus [192,194]. Based on experiments using octadeuterio-AA they showed that the 11- or 12-keto intermediate is not involved. Isolation and characterization of both HR- and 12R- hydro-peroxyeicosatetraenoic acids from incubations of desalted ammonium sulfate fractions of the egg homogenate with arachidonic acid support involvement of a lipoxygenase. 

The characterization of the rhodium complexes formed under hydro-formylation conditions by NMR techniques and in situ IR spectroscopy showed that there is a relationship between the structure of the [RhH(CO)2 (P-P)] (P-P = 4, 19-23) species and their enantiodiscriminating performance. In general, enantioselectivity was highest with ligands that have a strong bis-equatorial (ee) coordination preference, while an equilibrium of... 

In summary, it can be stated that the characterization of sorption of hydro-phobic compounds to the organic matter of solid phase particles by Koc values is a useful model for solids with a high organic carbon content and negligible...

Chromatographic approaches have been also used to separate nanoparticles from samples coupled to different detectors, such as ICP-MS, MS, DLS. The best known technique for size separation is size exclusion chromatography (SEC). A size exclusion column is packed with porous beads, as the stationary phase, which retain particles, depending on their size and shape. This method has been applied to the size characterization of quantum dots, single-walled carbon nanotubes, and polystyrene nanoparticles [168, 169]. Another approach is hydro-dynamic chromatography (HDC), which separates particles based on their hydro-dynamic radius. HDC has been connected to the most common UV-Vis detector for the size characterization of nanoparticles, colloidal suspensions, and biomolecules [170-172]. 

An additional problem arises with the difficult analytical characterization of the cyclic peptide libraries. This is preferably performed by mass spectrometry, although there are limitations with the ionization method. In fact, FAB-MS leads to overexpression of hydro-phobic components by ion suppression, whereas in MALDI-MS preferentially hydrophilic...

The oxidation of a suitable lithium salt precursor leads to isolable and structurally characterized l-hydro-1,3-diphosphete radical 33. The EPR 31P and 13C hyperfine parameters were experimentally determined, simulated, and assigned with the help of theoretical calculations (Figure 2) <2006AGE4341>.
