Cancer is a worldwide public health problem, and its incidence in the world grew by 20% in the last decade. Zinc, an essential trace element, is involved in many cellular processes. Concerning prostate cancer, Zn could inhibit the growth of tumor cells, by inducing cell cycle arrest or apoptosis. X‐ray microfluorescence (μXRF) is an elemental analysis technique that allows mapping biologically important...
The promise of gold nanoparticles (AuNPs) in cancer applications remains an active area of research. The assessment of tumoral uptake can provide valuable insights into their intended efficacy. Total X‐ray reflection fluorescence (TXRF) spectroscopy offers low detection limits coupled with direct quantification through internal standardization. These features enable TXRF to measure uptake of AuNPs...
