Item Open Access Noncovalent functionalization of a nanofibrous network with a bio-inspired heavy metal binding peptide(2013) Garifullin, R.; Ustahuseyin, O.; Celebioglu A.; Cinar, G.; Uyar, Tamer; Güler, Mustafa O.Peptide-polymer nanofibrous networks can be developed to obtain hybrid systems providing both functionalities of peptides and stability and processability of the polymers. In this work, a bio-inspired heavy metal binding peptide was synthesized and noncovalently immobilized on water-insoluble electrospun hydroxypropyl-beta-cyclodextrin nanofibers (CDNF). The peptide functionalized hybrid nanofibers were able to bind to heavy metal ions and facilitated removal of metal ions from water. The peptide-polymer scavenging system has potential for development of further molecular recognition systems with various peptide sequences or host-guest inclusion complexes. © 2013 The Royal Society of Chemistry.Item Open Access A supramolecular peptide nanofiber templated Pd nanocatalyst for efficient Suzuki coupling reactions under aqueous conditions(Royal Society of Chemistry, 2012) Khalily, M. A.; Ustahuseyin, O.; Garifullin, R.; Genc, R.; Güler, Mustafa O.A bioinspired peptide amphiphile nanofiber template for formation of one-dimensional Pd nanostructures is demonstrated. The Pd and peptide nanocatalyst system enabled efficient catalytic activity in Suzuki coupling reactions in water at room temperature. The nanocatalyst system can be easily separated and reused in successive reactions without significant loss in activity and structural integrity. © 2012 The Royal Society of Chemistry.
