Geodesic surfactant structures
Article Abstract:
Novel vesicle aggregates have been characterized using freeze-fracture electron monographs that have geodesic spheres or raspberry-like shapes. These multi-niosomes were created through dissolving sorbitan mono-oleate, cholesterol and dicetyl phosphate in chloroform and using oxygen-free nitrogen to dry the lipid film generated after the organic solvent was removed. The vesicle-vesicle interactions in these shapes may help in understanding cell-cell interactions and may serve as useful drug delivery vehicles.

Isolating RNA from whole blood - the dawn of RNA-based diagnosis?
Article Abstract:
Catrimox-14 is a novel cationic surfactant solution that is used in the lysis of cells for RNA and DNA precipitation. Either extraction with hot buffered formamide precipitation, followed by ethanol precipitation, or with guanidinium isothiocyanate followed by extraction at slightly acid pH and isopropanol precipitation is used to recover RNA from the pellet. The method offers an RNA extraction procedure that is simpler than conventional methods.

Dependence of aggregate morphology on structure of dimeric surfactants
Article Abstract:
A series of surfactants linked by a hydrocarbon spacer (CsH2s) are synthesized to study the effects of disturbing the arrangement of polar heads on the properties of surfactants in aqueous solution. The short spacers promoted micelle growth and lead to viscoelasticity in the said surfactants, CsH2s-alpha, omega -(C12H25N+(CH3)2Br-)2. The technique used could be useful in the regulation of ampiphile self-aggregation.
