(a) Absorbance spectra of cuvettes irradiated to 200 Gy. The maximum absorption is 630 nm for the WE PRESAGE as well as AuNPs and BiNPs at 0.5 mM; (b) example of a group of irradiated cuvettes: two cuvettes irradiated to 50 Gy, 100 Gy and 200 Gy for each 5–50 nm BiNP concentration: 0 mM, 0.25 mM, 0.5 mM and 1.0 mM. |
