Fig. 1From: De novo design of a pH-triggered self-assembled β-hairpin nanopeptide with the dual biological functions for antibacterial and entrapmenta Schematic of the SAP. b The three-dimensional structure of SAP modeling by http://zhanglab.ccmb.med.umich.edu/I-TASSER. The hydrophobicity spectrum: red-white-blue (− 4.5 ~ + 4.5). c Concentration-dependent self-assembly of the SAP. ANS fluorescence binding assay for the SAP at different concentrations at pH 5.0, 6.0 and 7.0. d The critical aggregation concentrations of the SAP at pH 5.0, 6.0 and 7.0. e TEM images and f CD spectra of SAP nanoparticles under three pH conditionsBack to article page
