WebFeb 2, 2010 · The peptide-amphiphile gel was monitored by parallel-plate rheometry, and the elastic modulus (G') was greater than the viscous modulus (G''), which indicates that PR_g forms a gel. The shear modulus for a 2 day old gel was measured to be approximately 500 Pa, which is within the modulus range for living tissue; thus, the PR_g gel shows ... WebNitric oxide-releasing peptide amphiphile nanomatrices within the range of 16.25 µmol to 130 µmol were used to analyze MIN-6 cell behavior. Both 32.5 µmol and 65 µmol peptide amphiphiles showed improved MIN-6 functionality in response to glucose over a 7-day time period, and the elevated functionality was correlated with both PDX-1 and ... how to send a folder without zipping it
