Cover Picture: Programmable Motion and Separation of Single Magnetic Particles on Patterned Magnetic Surfaces (Adv. Mater. 14/2005)

17_14/2005Structured magnetic surfaces enabling programmable motion of single micrometer-sized magnetic particles are reported on p. 1730 by Gunnarsson and co-workers. Patterns of thin-film magnetic elements are tailored to form transport lines with junctions for the separation of individual particles. This method has the potential to improve and generate new applications in biotechnology. The cover shows a schematic of the transportation and separation of magnetic particles functionalized with antibodies capable of selectively capturing the corresponding analytes from a sample.
