Figure 3. Effect of porosity and surface zeta potential of S1MP on BASP formation.

Figure 3

(A) SEM micrographs demonstrating the importance of porosity in the association of the AuNP-bacteriophage networks with S1MP having (i) 20–30nm pores, (ii) 40–60nm pores, (iii) nonporous surface; (B) Zeta potential of BASP and their components (inset) SEM image of BASP with S1MP(-) and S1MP(+) showing better adhesion of AuNP-bacteriophage networks to the S1MP(+) in comparison to S1MP(-); (C) Contact angle measurements of BASP showing an increase in hydrophilicity in comparison to AuNP or AuNP-bacteriophage.
