Optical characterization of BA, BN, and (BA)0.72(BN)0.28 helical assemblies. When excited by (a) blue and (b, d and f) green light, fluorescence microscopy images of (a, b) BA tubes, (d) BN tubes, and (f) (BA)0.72(BN)0.28 helices. Scale bars, 25 μm in a, b, 50 μm in d, and 20 μm in f. Bright-field optical microscopy images of (c) BN tubes and (e) (BA)0.72(BN)0.28 helices. Scale bars, 50 μm in c and 20 μm in e
