X-ray fluorescence (XRF) imaging is a powerful technique for mapping elemental distributions, particularly metals, in biological tissues [1]. However, its broader application is constrained by the scarcity of effective contrast agents. To address this limitation, we developed a novel strategy that uses an approach to trigger site-specific growth of metal nanoparticles (NPs) in situ, enhancing...

Recent studies have revealed the presence of diverse bacteria within solid tumors of cancer patients. The intrinsic tumor-targeting properties of these bacteria, along with the selective colonization observed in animal models, have renewed interest in employing bacteria as carriers for cancer therapy. However, due to the limitations of current in vivo imaging technologies, the... -
