Manufacturing of a Secretoneurin Drug Delivery System with Self-Assembled Protamine Nanoparticles by Titration
Fig 5
AFM images of secretoneurin loaded proticles.
Images recorded by atomic force microscopy showed spherical secretoneurin loaded proticles for mass ratio of 1 : 1 : 1.5 prepared by titration process (A) as well as by single protamine addition (B). Triangular clustered proticles were recorded for mass ratio 1 : 0.25 : 1.5 prepared by protamine addition at once (C).
