Streptavidin Coverage on Biotinylated Surfaces [PDF]
ACS Applied Materials & Interfaces, 2021 Biosensors and other biological platform technologies require the functionalization of their surface with receptors to enhance affinity and selectivity. Control over the functionalization density is required to tune the platform's properties. Streptavidin (SAv) monolayers are widely used to immobilize biotinylated proteins, receptors, and DNA.

Nanomechanics of Streptavidin Hubs for Molecular Materials [PDF]
, 2014 A new strategy is reported for creating protein-based nanomaterials by genetically fusing large polypeptides to monomeric streptavidin and exploiting the propensity of streptavidin monomers(SM) to self-assemble into stable tetramers.

Novel approaches for the creation of artificial metalloenzymes [PDF]
, 2013 Artificial metalloenzymes can be defined as the fusion of chemo- and enzymatic catalysts by insertion of non-specific achiral catalytic moieties into the chiral environment of a protein cavity, thereby broadening the scope of both fields.

Spontaneous Dissociation of Streptavidin from Biotinylated Double Stranded DNA [PDF]
, 2017 The binding of streptavidin to biotin is one of the strongest non-covalent interactions observed in nature. However, we have observed that streptavidin rapidly dissociates from biotinylated double stranded DNA in the presence of free biotin. In contrast,
