Improving SERS Detection of Bacillus thuringiensis Using Silver Nanoparticles Reduced with Hydroxylamine and with Citrate Capped Borohydride
Figure 6
Changes in color of borohydride reduced Ag-NPs when mixed with bacterial samples and aggregated with NaCl 1.0 M. (a) Color of borohydride reduced NPs; (b) Slight change in color when Bt suspended in 0.1 M NaCl was added to sol; (c) Color of the borohydride reduced Ag-NPs aggregated with 1.0 M NaCl; (d) color of suspensions when Bt suspended in 0.1 M NaCl was added.
