Optically active spin defects in diamond and hBN are promising solid-state quantum sensors but often fall short for chemical sensing. Here the authors show that BN nanotubes hosting such defects create a nanoporous, omnidirectional quantum “mesh” sensor at room temperature, enhancing chemical detection through high surface area and improved sample accessibility.
