T/R	Pink	PinkOrange1.tif	92% gold: 8% silver (Measured in TEM, Mod 3 Day 3)	The observed nanowire in PinkOrange1.tif is greater than 900 nm in length, suggesting that it is comprised of multiple phages. Image PinkOrange3_Silver disk.tif shows hexagonal disk structures which are crystallized silver nano-particles. Length scales: 100nm for PinkOrange3_Silverdisk.tif; 200nm for everything else
	Grape	GrapeBlue.tif	Scale in photo is 200nm. Web of nano wires is approximately 20-50nm in diameter and from its length is likely composed of multiple phage. 85% Au/ 15% Ag. Possible reasons for high proportion of gold: Silver crystallizes more readily than gold as seen in PinkOrange3_Silver disk.tif, sequestering of silver in these larger structures would have decreased the amount of silver available to bind to phage. Also p8 was selectively mutated to bind with a high affinity to gold therefore preferential binding of gold over silver to be expected.
