Title: Batch-fabricated gradient and RF coils for submicrometer resolution magnetic resonance imaging and manipulation

Abstract: A batch micro-fabricable array of dimensionally scaled-down Integrated Micro Coil Structure (IMCS) having a plurality of multi-layer gradient coils and a set of RF coils is disclosed for Magnetic Resonance Imaging (MRI). The coil traces are made of electrically conductive material. The key scaled-down parameters include a maximum coil size of about 20 .mu.m in diameter, a minimum layer thickness of about 20 .mu.m, an analysis chamber size of 50 .mu.m and an overall IMCS size of less than 10 mm. Coupled with an external MRI electronic driving and signal acquisition system, the IMCS functions to capture the three dimensional image of a magnetic nano article, located within the IMCS analysis chamber, with a high resolution of less than a .mu.m. Also disclosed is a method of driving a small magnetic object having a magnetic moment, also located within the analysis chamber, by properly energizing the gradient coils.
