Target analyte detection devices include a housing having a potentiostat and a microcontroller coupled to the potentiostat. The device also includes a substrate having a plurality of electrodes on a first surface of the substrate. A first set of electrodes of the plurality of electrodes defines a first sample detection region. The substrate is removably attachable to the housing such that the first set of electrodes is coupled to the potentiostat upon attaching the substrate to the housing. The device also includes a magnet assembly couplable to a second surface of the substrate. The magnet assembly includes a magnet positioned in the magnet assembly such that a magnetic field from the magnet extends through the substrate and the first set of electrodes into an area above the first sample detection region upon coupling the magnet assembly to the substrate.

Magnetic electrochemical sensing

Described herein are micro-coil hyperpolarized NMR systems and methods for measuring metabolic flux in living and non-living samples. Such systems can perform high throughput measurements (with multiple coils) of metabolic flux without destroying the material, making it useful to analyze tumor biopsies, cancer stem cells, and the like. In certain embodiments, a hyperpolarized micromagnetic resonance spectrometer (HMRS), described herein, is used to achieve real-time, significantly more sensitive (e.g., 10-fold more sensitive) metabolic analyses of live cells or non-living samples. In this platform, a suspension mixed with hyperpolarized metabolites is loaded into a miniaturized detection coil (e.g., about 2 &#x3bc;L), where the flux analysis can be completed within a minute without significant changes in viability. The sensitive and rapid analytical capability of the provided systems enables rapid assessment of metabolic changes by a given drug, which may direct therapeutic choices in patients.
