From soft to hard rod behavior in liquid crystalline suspensions of sterically stabilized colloidal filamentous particles.
The liquid crystalline phase behavior of a colloidal system of sterically stabilized rods is reported. Our colloidal suspensions consist of highly monodisperse, semi-flexible filamentous viruses which have been coated with neutral hydrophilic polymers by irreversibly binding poly(ethylene glycol) (PEG) to the surface of the virus particles. Depending on the size of the grafted polymer, up to th...
متن کاملLiquid crystal phase behavior of sterically-stabilized goethite.
The liquid crystalline phase behavior of sterically-stabilized goethite particles in toluene was studied using small-angle X-ray scattering. The results were compared with those from charged particles in water, with and without magnetic field: similarly rich phase behavior was found. Furthermore, the special magnetic properties were retained after coating the particles with amino-functionalized...
متن کاملCharge - stabilized colloidal suspensions . Phase behavior and effects of confinement *
The Poisson–Boltzmann (PB) equation is used to investigate effective colloid-interface interactions and the phase behavior of charge-stabilized colloidal suspensions. When a colloidal particle, immersed in an electrolyte, approaches an interface, which may be neutral (such as air) or charged (like electrodes, glass, etc.), image charge effects plus the deformation of the colloidal ion atmospher...
متن کاملIntravitreal delivery of oligonucleotides by sterically stabilized liposomes.
PURPOSE The efficacy of sterically stabilized liposomes for delivering a model phosphodiester oligonucleotide intravitreally was investigated in the rabbit. METHODS Ocular distribution and clearance from the vitreous humor of a model 16-mer oligothymidylate (pdT16) were evaluated in the rabbit by radioactivity measurements after intravitreal injection of either a solution or liposomes contain...
متن کاملTreatment of visceral leishmaniasis with sterically stabilized liposomes containing camptothecin.
The efficacy of 20(S)-camptothecin (CPT), free and incorporated into sterically stabilized liposomes, has been investigated in vitro against Leishmania donovani promastigotes and in vivo in a murine model of visceral leishmaniasis. Incubation of L. donovani promastigotes with free or liposomal CPT inhibited the growth of parasites in a dose-dependent manner. Tissue distribution studies revealed...
