Magnetic Resonance Spectroscopy (MRS) is a powerful, non-invasive method with significant potential in fundamental research, drug development, personalized medicine, and beyond [1-3]. Micro-NMR, an emerging field within NMR, has increased sensitivity and reduced sample volume demands, paving the way for new applications in portable NMR and mass-limited biological samples [4-7]. We present a novel, scalable, and user-friendly micro-NMR probe system featuring a single-chip transceiver, microcoil, and 3D micro-printing [8-9]. This system can be used with standard NMR spectrometers for measurements of samples with volumes between 10 nL and 100 pL at frequencies between 150 MHz and 600 MHz. The CMOS-based design enables simultaneous acquisition from multiple sensor coils on the same device, and additive manufacturing allows customization for various magnets, spectrometer systems, and applications. This presentation will discuss the system architecture, features, and performance, as well as prospects for future developments. We demonstrate the probe's utility in nanoliter-size human 3D cell cultures, early mammalian embryos and oocytes, highlighting its potential for disease monitoring in microscopic cell cultures.
