Rezumat: This paper reports the design, the fabrication and preliminary tests of planar microcoils used as Nuclear Magnetic Resonance radio-frequency detection coils. The magnetic coupling between a RF coil and a sample is maximized by physically designing the coil as small as possible as to just accommodate the sample. Maximum coupling corresponds directly to an optimal sensitivity for the signal reception. Designed for a biological application, these coils have to be as less invasive as possible and they must allow studying small quantities of metabolites surrounding the microcoil. NMR micro-spectroscopy experiments have been performed in water and butter samples using a 5001000 µm² planar microcoil tuned and matched at 85.13 MHz (proton’s frequency at 2 T). | |||||||
