Table 1.

PDT photosensitizers, their activation wavelengths and their relative uptake ratios. The uptake ratios data were taken from Table 3 in [8] for (a) 5mg.kg⁻¹ administered dose and 24hrs delay, (b) 100mg.kg⁻¹ administered dose and 6hrs delay, (c) 1mg.kg⁻¹ administered dose and 24hrs delay, and (d) 0.5mg.kg⁻¹ administered dose and 24hrs delay. Those ratios were calculated based on the tissue specific uptake ratios (SUR) as quantified tissue concentrations over administered concentrations in one (SnET as photosensitizer) to three animals.

Photosensitizer		Photofrin (a)	ALA (b)	SnET (c)	ALCIPc (d)
Activation Wavelength ( nm )		630	635	662	675
Relative Uptake Ratio	Tumor/Grey matter	10.6 ± 1.4	22 ± 3.4	1.5	12.7 ± 2.4
	Tumor/White matter	8.2 ± 0.9	72 ± 14	3.4	24.9 ± 4.3
