Hybrid polymer-peptide conjugates offer the potential for incorporating biological function into synthetic materials. The secondary structure of short helical peptides, however, frequently becomes less stable when expressed independent of longer protein sequences or covalently linked with a conformationally disordered synthetic

Biomaterials, 31(35), 9266-9272 (2010-09-25)
In the search for a cell-instructive or cell-interactive artificial extracellular matrix, synthetic hydrogels have been extensively investigated to apply three-dimensional (3D) cell culture and tissue engineering. Here, we are reporting a reverse thermal gelling l/dl-polyalanine block copolymer aqueous solution for

Non-equilibrium molecular dynamics simulations of a solvated 21-residue polyalanine (A21) peptide, featuring a high propensity for helix formation, have been performed at 300 K and 1 bar in the presence of external electromagnetic (e/m) fields in the microwave region (2.45

As a new application of a thermogel, a poly(ethylene glycol)-b-poly(L-alanine) (PEG-L-PA) gel encapsulating fibroblasts was investigated for wound healing. The fibroblasts were encapsulated by the temperature sensitive sol-to-gel transition of the polymer aqueous solution. Under the in vitro three-dimensional (3D)

The amide I mode is a highly structure sensitive vibration of polypeptides that gives rise to a very strong band in IR absorption and a moderate band in Raman spectra. Many theoretical simulations of IR-band profiles have been undertaken thus
