Abstract
Here we report a method which uses chemical deposition of silver nanoparticles on the biological template. These templates we use in all experiments are films inclusive of SLFF (S-layer fraction film) extracted from Deinococcus radiodurans RT3. The S-layer fraction film of Deinococcus radiodurans RT3 contacts directly to its environment and has unique physical and chemical properties. Taking advantage of the chemical property of S-layer fraction film surface, we can reduce the silver ions to nanoparticles, then attach the nanoparticles on the biological templates and form a silver film. We use UV/VIS spectrometer to monitor the formation of silver nanoparticles. Besides, we also use transmission electron microscopy to observe the distribution of nanoparticles size of different reaction time. Meanwhile, we use fluorescent microscope、confocal microscope and photoluminescence to observe varieties and emissive property of the silver nano-films.
