An electrochemical microsensor system to monitor the pericellular oxygen concentration of fibroblasts during low-level light therapy in vitro was developed. The system provides in-sight into the metabolism of the cells during and in consequence of il

We present a cell culture monitoring platform to study effects of photodynamic therapy (PDT) on cancer cells. For the first time, it was possible to observe differences in cellular respiration at the transition between treated and untreated tumor cel

Clark-type oxygen microsensors promise zero analyte consumption if the feedback mode (Ross principle) is successfully implemented. Our approach was a microsensor with platinum as working and counter electrode material, a pHEMA hydrogel layer containi

We introduce a new system which combines metabolic monitoring using electrochemical microsensors with photodynamic therapy on-chip for the first time. Oxygen consumption of T-47D breast cancer cells was measured during therapy with protoporphyrin IX.

A microsensor system to investigate photodynamic therapy of cancer cells in vitro was established. Monitoring of the cellular respiration during and after photodynamic therapy was demonstrated. The system comprises a sensor chip with cell culture cha

This paper reports on fabrication and characterization of a true Clark-type microsensor to monitor oxygen locally in cell culture. We were able to implement the Ross principle to achieve zero analyte consumption, as verified by reading the counter el

An electrochemical microsensor system to investigate photodynamic therapy of cancer cells in vitro was developed and applied to monitor the cellular respiration during and after photodynamic therapy. The redox activity and therefore influence of the
