Review and outlook: from single nanoparticles to self-assembled monolayers and granular GMR sensors
Beilstein J. Nanotechnol. 2010, 1, 75–93, doi:10.3762/bjnano.1.10
- interactions is discussed. Keywords: bottom-up particle synthesis; dipolar particle coupling; granular giant magnetoresistance sensor; magnetic nanoparticles; self-assembly; Introduction Magnetic nanoparticles have been thoroughly studied during the last decades due to their many promising applications in
- , nanoparticle fabrication by bottom-up chemical syntheses offer significant advantages: The systematic adjustment of the self-organization process by, e.g., the employment of ligands with different alkyl chain lengths, allows for the independent variation of the particle-matrix volume fraction and the inter
- geometrical configuration. The bottom-up method may be understood as an approach from the opposite direction: A small precursor, commonly an organometal compound or a salt, is decomposed by either thermal or optical excitation, which separates the metal atom from the organic residue, or by a reducing agent
Preparation, properties and applications of magnetic nanoparticles
Beilstein J. Nanotechnol. 2010, 1, 21–23, doi:10.3762/bjnano.1.4
- now both, physics and chemistry related approaches. Furthermore, the meanwhile widely accepted distinction between top down and bottom up preparational methods can be applied to the fabrication of NPs as well. Examples for top down approaches are sculpting NPs out of a previously deposited thin film
- minimizing dewetting process on top of an appropriately chosen substrate [5]. Bottom up approaches mainly can be divided into gas phase condensation [2] or various wet chemical routes [1]. Besides scientific curiosity, the motivation behind all these preparational efforts is certainly to obtain NPs optimized
