Abstract

dSynthetic sugar-, peptide-, and nucleobase-appended bolaamphiphiles generally self-assemble in aqueous media to form nanoscale or mesoscale high-axial-ratio microstructures (HARMs), such as fibers, tubes, and rods. Aiming at examining fine morphologies and hierarchical structures of these organic HARMs under in situ conditions, we employed confocal laser scanning microscopy (LSM), energy-filtering transmission electron microscopy (EF-TEM), cryo-TEM, atomic force microscopy (AFM), and dark-held light microscopy (DFLM). As a result, we were able to obtain well-resolved microscopic images that reflected the original forms, without damaging or changing the morphologies. Here we describe a variety of HARM images and their characteristics. The images obtained include (1) a cross-section profile of a twisted fibrous HARM observed;ed using LSM, (2) direct LSM observation in water of fibrous HARM with a width of less than 1 mu m, (3) EF-TEM observation of twisted HARMls without the need for prior staining, (4) boundary water on surfaces of fibrous HARM observed using cryo-TEM, (5) thickness evaluation of st microtube membrane using AFM, and (6) effective DFLM observation of double-helical rapes.
