10. A solution contains both gold nanoparticles (which absorb at 520 nm) and DNA (which absorbs at 260 nm) in a hybrid drug delivery construct. The absorbance at 260 nm is 0.192 and at 520 nm is 0.426. A 1 cm cuvette was used to take the measurements. The molar absorptivity at each wavelength is shown in the following table: Species E at 260 nm (M-cm-) E at 520 nm (M-'cm-1) Au nanoparticles 8.31 x 105 9.406 x 108 DNA 2.84 x 106 7.21 x 105 Find the concentrations of Au nanoparticles and DNA in the solution.
