Metal nanoclusters (MNCs), including Ag NCs, Cu NCs, and Au NCs, can be used as fluorescent probes for nucleic acid testing. Identification of DNA fragments and trace detection of miRNA (LOD as low as aM) can be achieved.

X-ray powder diffraction data, unit-cell parameters, and space group for N,N-dimethyl-1H-benzo[d]imidazol-2-amine, C9H11N3, are reported [a = 11.379(3) Å, b = 10.227(5) Å, c = 7.151(1) Å, α = 90°, β = 90°, γ = 90°, unit-cell volume V = 832.318 Å3, Z = 4, ρcal = 1.286 g cm−3, and space group P21212]. All measured lines were indexed and were consistent with the P21212 space group. No detectable impurities were observed.
