MUNICH, Germany, Oct. 22 (UPI) -- German scientists say they have developed a microchip biosensor that can assist in determining how effective a cancer drug might be in individual patients.
The scientists at the Technical University of Munich said it's very difficult to predict whether a cancer drug will help a patient since only approximately one third of drugs will work directly in a given patient.
So the researchers developed a new test process for cancer drugs. With the help of microchips, they said they can establish in the laboratory whether a patient's tumor cells will react to a given drug. The sensor could help in the future with the rapid identification of the most effective medication for an individual patient.
As part of another research project, the scientists said they are also developing a sensor chip intended to control tumor growth. The chip, implanted in the vicinity of a tumor, would release cancer drugs or pain medication only when the tumor grows. The researchers said such a sensor system could be used in the treatment of inoperable tumors.
