Oxygen measurement in tissues

Tissue regeneration has accelerated from using hydrogels, but a next step is to see and be sure that oxygen is reaching the cells.  To that end,  “. . . researchers at Rice University have developed special microparticles, that are soft and non-toxic to living cells, that glow in relation to how oxygenated their environment is. These microparticles [made of palladium and a fluorophore] are particularly well suited to measuring oxygen within three-dimensional structures, such as hydrogels because they’re relatively bright and can be seen from outside such constructs.”     MORE
