Single-strand macromolecule

Note 1 Except in linear single-strand macromolecules, the definition of a chain may be somewhat arbitrary. 

Polymer, the macromolecules of which are single-strand macromolecules. 

A polymer the macromolecules of which are single-strand macromolecules, i.e. macromolecules comprising constitutional units connected in such a way that adjacent constitutional units are joined to each other through two atoms, one on each constitutional unit [3, 7, 9].

Fig. 7 Approaches for linking macromolecules to solid surfaces using biotin-strept(avidin) systems. Either biotin or streptavidin may be directly linked to a surface (e.g. Fig. 6). There are a large number of biotin derivatives with different spacer arms (e.g. Fig. 3) that may be used for immobilization. The choice of a specific biotin depends on which active group occurs on the native or derivatized surface. Attachment of strept(avidin) may be done with methods used with other proteins. Note that the deposition of a biotinylated molecules to a surface may also be used (e.g. biotinylated small molecules or large molecules like BSA) to link strept(avidin) to a surface. A DNA covalently attached at one end (3 end) can have a functional biotin at the other end that could bind to strept(avidin) or be covalently linked to streptavidin (see Fig. 4). Single-stranded DNA bound to immobilized streptavidin is available for hybridization to its complementary sequence (See Fig. 4)...
