Artificial spider silk from ion-doped and twisted core-sheath hydrogel fibres
Nature Communications, 2019 Spider silks show unique combinations of strength, toughness, extensibility, and energy absorption. To date, it has been difficult to obtain spider silk-like mechanical properties using non-protein approaches. Here, we report on an artificial spider silk

Molecular Spiders in One Dimension [PDF]
Journal of Statistical Mechanics P08027 (2007), 2007 Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs. Different mappings are established between various models of spiders and simple exclusion processes.
