Abstract

We report on use of coverslip-based microwave antenna as an experimental platform for quantitatively characterizing NV spin properties of different types of fluorescent nanodiamonds (NDs). This coverslip antenna provides as-designed magnetic field of microwaves for spin excitation, thereby precisely determining NV spin relaxation times (T1, T2) of conventional type-Ib NDs and 12C-enriched NDs. Furthermore, we demonstrate measurements of the spin relaxation times inside live cells (HeLa and HepG2). We discuss potential applications of 12C enriched nanodiamonds for biologicals sensing with our coverslip antenna devices.
