Raman spectroscopic study of boundary lipid in 1,2-dipalmitoylphosphatidylcholine/apolipoprotein A—I recombinants

Characterization of progesterone loaded biodegradable blend polymeric nanoparticles

“…This behavior is clearer for PCL and PHBV/PCL nanoparticles. EDWARDS et al (1993) point out that such behavior indicates an increase in the crystallinity degree of the alkyl side chain of lecithin.…”

FT-IR Investigation of the Urea State in AOT Reversed Micelles

“…The value of A (1.11) of all the investigated urea/AOT/CCl 4 solutions indicates that AOT is in micellar form. Moreover, the CH stretching band shape does not change with R urea , emphasizing that urea encapsulation in the micellar core does not significantly affect the lateral packing order of surfactant chains and their conformational dynamics (33).…”

Spectral characterization and colloidal properties of 1-hexadecylpyridinium chloride in aqueous binary mixtures of different glycols

“…4a, assigned to anti symmetric -CH 2 stretching mode for CPyCl in water. The -CH 2 anti symmetric stretching mode is a good probe of state of surfactant alkyl chain because it is sensitive to their lateral packing order and conformational dynamics [28]. This peak shows a significant height increase, peak sharpening and shift slightly towards the lower frequency with the incorporation of glycols in water media.…”
