• medicine. In general, biological samples have only negligible magnetic susceptibility. Thus, using magnetic nanoparticles for biosensing not only enhances sensitivity but also effectively reduces sample preparation needs. This review focuses on the use of magnetic nanoparticles for in vitro detection of

• molecular measurements into clinical settings, however, an assay would need to 1) provide high sensitivity and specificity, 2) minimize sample preparation and sample volume, and 3) ideally allow concurrent detection of diverse target moieties through multiplexed measurements. Biosensing strategies based on

• their longitudinal relaxivities (r1), T2 is used for NMR-based biosensing applications. With a higher r2 relaxivity, fewer numbers of nanoparticles are required to produce detectable T2 changes. Within an ensemble of MNPs, magnetic relaxation properties depend on more than simply the particles

In recent years, researchers have paid much more attention to the construction of electrochemical enzyme biosensors for the analysis of amino acids [5][6][7], and several electrochemical biosensing systems for L-proline and D-proline determination have been reported
