“…We prepared two DTPA-bisamides that can react with styrene via chain transfer reactions via hydrogen abstraction from the benzylic carbon of the DPTA-bisbenzylamide (DTPA-BAm 2 ) or the allylic carbon , of DTPA-bisallyamine (DTPA-ALAm 2 ). The results were compared with those obtained in the co-polymerization with DPTA-bis-4-vinylbenzylamide (DTPA-VBAm 2 ), where the 4-vinylphenyl group would be expected to have a reactivity similar to that of styrene. − The resulting products were characterized by 1 H NMR to confirm their structures.…”

Mass cytometry (MC) is an emerging analytical technique in which an inductively coupled plasma time-of-flight mass spectrometer is employed to analyze the signals of isotopic labels on cell and microbead samples. Bead-based applications in mass cytometry require one to label the microbeads with various metal ions that can be individually identified by MC. This paper describes a novel approach to encoding microbeads with controlled levels of metal ions by introducing polymerizable metal complexes of the structure M(DTPA-VBAm2) in two-stage dispersion polymerization reactions. Using this method, the incorporation of various metal ions is effective and consistent in the investigated concentration range. As a result, this method provides a convenient path for synthesizing microbeads with controlled metal content for mass cytometry applications. As a proof-of-concept experiment, a sample of europium-labeled microbeads was surface-functionalized with a goat anti-mouse IgG antibody and tested by mass cytometry for its ability to detect a Lu-labeled mouse IgG. Surface functionalization involved a thin silica shell to which neutravidin was covalently attached. This experiment demonstrates the potential use of these microbeads as classifier beads for bead-based assays in MC.

“…Recently, functionalized rod-coil molecules have been studied by researchers for construction of nano-scale materials with potential electrophoto properties [7][8][9][10][11][12][13] . Self-assembly of rod-coil block molecules provide various supramolecular nanostructures from 1-D lamellar, 2-D columnar, 3-D bundles in the bulk state, through non-covalent forces including hydrophobic and hydrophilic effects, electrostatic interaction, hydrogen bonding and microphase segregation [14][15][16][17][18][19][20][21][22][23] . It has been reported that molecular parameters such as volume fraction of rod to coil segment, the crosssectional area of coil segment, the shape of rigid rod segment dramatically influence driving force of molecules to form various nanostructure [24][25][26][27] .…”

Rod-coil molecules have a strong tendency to self-organize into supra-molecular nanostructures in the bulk state. In this article, we report synthesis and self-assembling behaviour of rod-coil molecules 1-3, consisting of a biphenyl and cholesteryl group as a rod segment and poly(ethylene oxide) (PEO) with a degree of polymerization of 7, 12 and 17 coil segments. Self-organization behaviour of these molecules investigated by means of differential scanning calorimetry, thermal polarizing optical microscopy and small-angle X-ray scattering in the bulk state reveal that volume fraction of PEO coil segments containing alkyl chain of cholesteryl group dramatically influence the self assembling behaviour of rod building block in the liquid crystalline phase. Molecules 1-3 self-assemble into 1-D bilayered structures with different d-spacing according to the lengths of coil domains in the solid state. While, self-organized molecular structures transfer into oblique columnar structure for molecule 1 and 2 from the crystalline to the liquid crystalline phase, further increasing coil to rod volume fraction, molecule 3 self assemble into hexagonal columnar aggregate through π-π stacking of rod building blocks.
