AuNP synthesis

Note: These AuNPs will be used in the silica coating procedure. See calculations below.

Calculating AuNP diameter and concentration

λspr= 527nm

d= [ln(λspr-λ0/L1)]/L2

where λ0= 512nm, L1= 6.53, and L2=0.0216 (These are fit parameters from theoretical calculations1)

d= [ln(527nm-512nm/6.53)]/0.0216

d= 38.5nm

c = A450/ε450

c = 1.89/(4.36x109)

c = 0.43nM

Calculating AuNP concentration in g/L
