New structures comprise rings of polymerized lipid molecules around nanotubes, the lipid molecules comprising one or two alkadiyne chains attached to a polar head group. New structures comprise rings of polymerized lipid molecules of formula (I) around nanotubes: (A)xZ (I) x = 1 or 2; A = CH3(CH2)m-CC-CC-(CH2)n-; n, m = 1-16; Z = COOH, CONHY, NH2, N+(R)3, (-OCH2CH2)2CHOCH2COOR2 or (-OCH2)2CHOR2 or a sugar or polysaccharide residue; R = 1-4C alkyl; Y = (CH2)4-CHR1-N(CH2COOH)2; R1 = H or COOH; R2 = COOH, CONHY1 or a sugar or polysaccharide residue; Y1 = (CH2)4-CHR3-N(CH2COOH)2; R3 = H or COOH. Independent claims are also included for: (1) production of the above structures by suspending crude nanotubes in a solution of the lipid molecules and polymerizing the lipid molecules that have self-assembled around the nanotubes; (2) purifying nanotubes by treating the above structures to remove the rings of polymerized lipid molecules. |
