Abstract: A method of manufacture of a sensor, the method comprising, in a first fabrication facility, forming one or more components of the sensor on a substrate; and in a second fabrication facility depositing a sensor layer, such as a magnetoresistive sensor, onto the substrate or over the one or more components. Otherwise contaminating effects of depositing magnetoresistive materials can thus be confined to the second fabrication facility, permitting more advanced fabrication equipment and techniques to be employed in the first fabrication facility.

Abstract: The present invention describes methods for preparing high quality nanoparticles, i.e., metal oxide based nanoparticles of uniform size and monodispersity. The nanoparticles advantageously comprise organic alkyl chain capping groups and are stable in air and in nonpolar solvents. The methods of the invention provide a simple and reproducible procedure for forming transition metal oxide nanocrystals, with yields over 80%. The highly crystalline and monodisperse nanocrystals are obtained directly without further size selection; particle size can be easily and fractionally increased by the methods. The resulting nanoparticles can exhibit magnetic and/or optical properties. These properties result from the methods used to prepare them. Also advantageously, the nanoparticles of this invention are well suited for use in a variety of industrial applications, including cosmetic and pharmaceutical formulations and compositions.
