Figure 3: Nanoparticle templating by BIND.
From: Programmable biofilm-based materials from engineered curli nanofibres
Silver nanoparticles were templated by A3-BIND biofilms incubated in aqueous AgNO3. Representative TEM micrographs demonstrate that PHL628 ΔcsgA cells producing wild-type CsgA (a) show no nanoparticle templating, whereas A3-BIND (b) templates nanoparticles after incubation in 147 mM AgNO3 for 4 h. (c) A higher magnification of the Ag nanoparticles organized on A3-BIND nanofilaments is shown. All scale bars are 0.5 μm.
