We present nanoscale nuclear magnetic resonance (NMR) measurements performed with nitrogen-vacancy (NV) centers located down to about 2 nm from the diamond surface. NV centers were created by shallow ion implantation followed by a slow, nanometer-by-nanometer removal of diamond material using oxidative etching in air. The close proximity of NV centers to the surface yielded large H-1 NMR signals of up to 3.4 mu T-rms, corresponding to similar to 330 statistically polarized or similar to 10 fully polarized proton spins in a (1.8 nm) 3 detection volume.
