In areas of biology and medicine, there is often a need for an analytical technique with the capability of quantitatively measuring chemical gradients at a subcellular level. One area of ongoing medical research where a methodology for subcellular chemical analysis is required is that of boron neutron capture therapy (BNCT) for the brain cancer glioblastoma multiforme and for certain types of melanomas.1,2 BNCT is based on the fission reaction that occurs when a boron-10 atom captures a thermal (
