NettetHoechst's excitation wavelength range, which has an excitation peak at 365 nm and partially overlaps with the UV-A wavelength range (315–400 nm), is another issue since it may have phototoxic impacts. All these findings from the eighties resulted in the dogma that Hoechst cannot be used during LCI. NettetHoechst 33342 were found to display two- or three-photon excitation from 810 to 910 nm. We examined the effect of excitation wavelength on the mode of excitation for DAPI and Hoechst 33342 in the solvent isobutanol and when bound to double helical DNA. For DAPI and Hoechst 33342 in isobutanol the mode of excitation changed from
