Nanoseparations: Strategies for size and/or shape-selective purification of nanoparticles

This paper reviews techniques currently available for size- and shape-selective purification of nanoscopic objects. The methods discussed range from variants of familiar chromatographic, centrifugation, or filtration techniques, to purification schemes deriving from nanoscale-specific phenomena, inc...

Description
Summary:This paper reviews techniques currently available for size- and shape-selective purification of nanoscopic objects. The methods discussed range from variants of familiar chromatographic, centrifugation, or filtration techniques, to purification schemes deriving from nanoscale-specific phenomena, including shape-selective reactivity, or propensity to form organized superstructures. This work reviews techniques currently available for size- and shape-selective purification of nanoscopic objects. The methods discussed range from variants of familiar chromatographic, centrifugation, or filtration techniques, to purification schemes deriving from nanoscale-specific phenomena, including shape-selective reactivity, or propensity to form organized superstructures. [Display omitted] ► Review of the methods of nanoparticle separation and purification. ► Overview of analytical techniques for the size- and shape-selective nanoseparations. ► Purification schemes deriving from nanoscale-specific phenomena.
