High-resolution Nmr Spectroscopy on a Chip by Structural Compensation of Magnetic Susceptibility Mismatch
نویسندگان
چکیده
Microfluidic compensation structures are introduced as a tool to homogenize magnetic field gradients present in microfluidic NMR spectroscopy. Magnetic field distortions are eliminated by compensating the magnetic susceptibility mismatch between the sample fluid and chip material through additional, lithographically defined compensation structures. This strategy will allow high resolution NMR spectroscopy on a chip, enabling a range of metabolomic applications.

Structural shimming for high-resolution nuclear magnetic resonance spectroscopy in lab-on-a-chip devices.
High-resolution proton NMR spectroscopy is well-established as a tool for metabolomic analysis of biological fluids at the macro scale. Its full potential has, however, not been realised yet in the context of microfluidic devices. While microfabricated NMR detectors offer substantial gains in sensitivity, limited spectral resolution resulting from mismatches in the magnetic susceptibility of th...
متن کاملAn optimised detector for in-situ high-resolution NMR in microfluidic devices.
Integration of high-resolution nuclear magnetic resonance (NMR) spectroscopy with microfluidic lab-on-a-chip devices is challenging due to limited sensitivity and line broadening caused by magnetic susceptibility inhomogeneities. We present a novel double-stripline NMR probe head that accommodates planar microfluidic devices, and obtains the NMR spectrum from a rectangular sample chamber on the...

Simultaneous analysis of explosives to identify, determine the purity and eliminate environmental pollution requires rapid, simple and cheap methods. Spectrophotometries method (UV-Vis), high-field proton nuclear magnetic resonance (1H-NMR), Raman spectroscopy and near infrared (NIR) are common methods that are applicable in two ways of direct and indirect in simultaneous analysis. In this poin...
متن کاملA Multidisciplinary Approach to High Throughput Nuclear Magnetic Resonance Spectroscopy
Nuclear Magnetic Resonance (NMR) is a non-contact, powerful structure-elucidation technique for biochemical analysis. NMR spectroscopy is used extensively in a variety of life science applications including drug discovery. However, existing NMR technology is limited in that it cannot run a large number of experiments simultaneously in one unit. Recent advances in micro-fabrication technologies ...
