Hydrophilic particles, charging

The pH-dependent properties of the hydrophilic positively charged colloidal particles favor the adsorption of negatively charged nucleic acids at acidic pH and at low salt concentration. However, the desorption is favored at basic pH and at high ionic strength. The concentration process of adsorbed nucleic acid materials was performed via centrifugation [9], filtration, or magnetic separation [10] of the used colloidal particles. [Pg.190]

This assures negligible repulsion between charged (surface active) oligomeric radicals and charged hydrophilic) particle surface with the same charge. [Pg.81]

Virus extraction and detection via hydrophilic and charged magnetic particles. ... [Pg.324]

Whilst organic polymer seeds are quite readily encapsulated by a PDMS shell (due to surface tension issues), PDMS cores need to be crosslinked and the organic polymer layer made hydrophilic by charged monomers such as (meth)acrylic acid, in order safely to achieve the expected core-shell structure. The grafting of styrene/ acrylonitrile (St/AN) onto a poly(butadiene) shell led to a striking change in the structure of the particles, from core-shell to a flocculated, moon-like configuration. [Pg.85]
