Fig. 14 Block copolymer,
comprising a non-uniform
polysarcosine block and a
uniform dodecapeptide,
assembles to curved sheets
in water (top image). Upon
heating, these transform
into well-defined tubes
(center image). Addition of
a block copolymer with a
shorter water-soluble block
leads to the formation of
three-way tubular structures
(lower image). Scale bars:
200 nm. Reproduced, with
