*We will attempt to form silver:protein nanofibers in a similar method as gold:protein nanofibers, using silver (I) nitrate, BSA, and HCl to bring the pH up to 3 (according to Dr Fox's previous work) | |||
*The final solution will have 0.25mM AgNO<sub>3</sub>, 1mM HCl, water, and defined ratios of BSA as detailed in the table below | |||
*All samples will be heated to 80C in an oven for 4 hours | |||
