Interaction with Synthetic Membranes
The major carotenoid pigment of a psychrotrophic Micrococcus roseus strain was purified to homogeneity from methanol extracts of dried cells by reverse-phase liquid chromatography and was designated P-3. On the basis of the UV-visible, infrared, mass, and 'H nuclear magnetic resonance spectra of P-3, it was identified as bisdehydro-,-carotene-2-carboxylic acid. The pigment interacted with synth...
متن کاملNanomechanical spectroscopy of synthetic and biological membranes.
We report that atomic force microscopy based high-speed nanomechanical analysis can identify components of complex heterogeneous synthetic and biological membranes from the measured spectrum of nanomechanical properties. We have investigated phase separated ternary lipid bilayers and purple membranes of Halobacterium salinarum. The nanomechanical spectra recorded on these samples identify all m...
متن کاملDynamics of lipids in synthetic membranes
Bilayer coliposomes were created from blends of head-group functionalized and non-functionalized synthetic lipids. Functionalized lipids in the outer leaflets of the bilayers were then chemically differentiated from the (unchanged) functionalized lipids of the inner leaflets, thus permitting study of the dynamics of the ensuing reequilibration that occurred via thermally activated transbilayer ...
متن کاملThe Electrical Properties of Synthetic Membranes
By the addition of n-butyl bromide to a 1:19 copolymer of 4-vinylpyridine and styrene, water-insoluble, strong polyelectrolytes can be prepared. The addition of a hydrocarbon plasticizer permits the casting of flexible films in which large polycations are immobilized but in which bromide ions (or other small anions) are free to move. Electrical measurements on these membranes showed that they c...
متن کاملThe Application of Gaussian Processes in the Prediction of Percutaneous Absorption for Mammalian and Synthetic Membranes
Improving prediction of the skin permeability coefficient is a difficult problem, and an important issue with the increasing use of skin patches as a means of drug delivery. In this work, we apply Gaussian Processes (GPs) with five different covariance functions to predict the permeability coefficients of human, pig, rodent and silastic membranes. We obtain a considerable improvement over quant...
