From: Development of functionalised polyelectrolyte capsules using filamentous Escherichia coli cells
TEM images of filamentous polyelectrolyte capsules. Polyelectrolyte capsules without additional S-layer polymer protein with palladium particles are shown in A and with additional S-layer polymer protein with palladium particles are shown in B. The darker tube shows a filament that contains bacterial cells that were not removed during the procedure. TEM image C shows the surface of S-layer polymer protein coated polyelectrolyte tubes with crystalline palladium particles. In D a TEM micrograph of single Pd-particles and an insert of a Fourier transformation analysis of such a particle are shown. The latter indicates by the measured distance of the lattice planes the crystalline nature of these particles.
