Klas Tybrandt, doctoral student in Organic Electronics at Linköping University, Sweden, has developed an integrated chemical chip. The results have just been published in the prestigious journal Nature Communications.
The Organic Electronics research group at Linköping University previously developed ion transistors for transport of both positive and negative ions, as well as biomolecules. Tybrandt has now succeeded in combining both transistor types into complementary circuits, in a similar way to traditional silicon-based electronics.
An advantage of chemical circuits is that the charge carrier consists of chemical substances with various functions. This means that we now have new opportunities to control and regulate the signal paths of cells in the human body.
