Contactless NMR spectroscopy on a chip
Contactless NMR spectroscopy on a chip
Inductively coupled planar resonators offer convenient integration of high-resolution NMR spectroscopy with microfluidic lab-on-a-chip devices. Planar spiral resonators are fabricated lithographically either by gold electroplating or by etching Cu laminated with polyimide. Their performance is characterized by NMR imaging as well as spectroscopy. A single-scan limit of detection LODt = 0.95 nmol s1/2 was obtained from sample volumes around 1 ?L. The sensitivity of this approach is similar to that obtained by microstripline and microslot probes.

Abstract
Inductively coupled planar resonators offer convenient integration of high-resolution NMR spectroscopy with microfluidic lab-on-a-chip devices. Planar spiral resonators are fabricated lithographically either by gold electroplating or by etching Cu laminated with polyimide. Their performance is characterized by NMR imaging as well as spectroscopy. A single-scan limit of detection LODt = 0.95 nmol s1/2 was obtained from sample volumes around 1 ?L. The sensitivity of this approach is similar to that obtained by microstripline and microslot probes.
