We have developed a one-step method for the synthesis of mesoporous upconverting nanoparticles (MUCNs) of the type NaYF4:Yb,Er@mSiO2 in ammoniacal ethanol/water solution. The mesoporous silica is directly encapsulating the hydrophobic upconversion nanoparticles (UCNs) due to the presence of the template CTAB. Intense green emission (between 520 and 560 nm) and weaker red emission (between 630 and...
Abstract: In cutaneous wound healing, the role of oxygen in vivo is poorly understood. We studied wound surface pO2 during physiological wound healing in humans. Split‐thickness skin graft donor sites (n = 12) served as standardized wound models. Wound surface pO2 was measured at 1, 6 and 14 days after split‐skin harvesting using two‐dimensional luminescence lifetime imaging (2D‐LLI) of palladium(II)‐meso‐tetraphenyl‐tetrabenzoporphyrin...
