Oriented Thin Film Formation by Surface Graft Polymerization of γ-Methyl l-Glutamate N-Carboxyanhydride in the Melt

Sum-frequency spectroscopy and imaging of aligned helical polypeptides

“…This is accomplished by first modifying the surface with initiators for subsequent the polymer synthesis, and then growing a helical chain that is tethered to the surface (grafting from approach) [39], [40]. Surface polymerization to produce PBLG monomolecular films has been performed in the melt [41], in solution [40], [42]- [45], and by a vapor deposition polymerization [46]. Vapor deposition polymerization was used in this paper to grow a PBLG film.…”

Electric-field-enhanced oriented cobalt coordinated peptide monolayer and its electrochemical properties

“…The fabrication techniques of the a-helical assemblies on the substrates have been well studied, such as the Langmuir-Blodgett (L-B) method [10][11][12], self-assembly [13][14][15][16][17][18] and the ring opening polymerization of N-carboxyanhydride of amino acids (NCA) on the initiator immobilized substrate surfaces [19][20][21][22]. These techniques offered a powerful platform for the formation of the a-helical peptide assemblies on substrate.…”

Photo-induced vectorial electron transfer through oriented metal-coordinated peptide assembly on a self-assembled monolayer

“…Studies on vertically and unidirectionally oriented peptide assembly systems may be important not only to the understanding of a simple and/or essential mechanism for the signal transduction through biological membrane but also may provide the basis for a molecular device capable of transferring information. The fabrication of vertically oriented α-helical peptide assemblies such as Langmuir-Blodgett (LB) films [5][6][7] and selfassembled monolayers (SAMs) [8][9][10][11][12] and grafted polypeptide layers prepared by the ring opening polymerization of Ncarboxyanhydride of amino acids (NCA) on the initiator immobilized substrate surfaces [13][14][15][16] has been reported. However, the LB films are practically insufficient because of the lack of physical stability due to the fact that the individual peptide chain remains unfixed.…”
