Testing cancer drugs in real time now closer to reality

Testing the effectiveness of drugs treating conditions such as cancer in real time may be closer to reality thanks to a new method for stacking synthetic DNA and carbon nanotubes on to a biosensor electrode.

The work, which may lead to more reliable ways to measure and manage diseases, is being pioneered by researchers at Purdue University.

Standard sensors employ metal electrodes coated with enzymes that react with compounds and produce an electrical signal that can be measured, but their inefficiency can lead to imperfect measurements.

The sensor described in the findings was designed for glucose, but researchers say it could be easily adapted for various compounds and mass-produced for personalised medicine.
