BIOELECTRONICS & DIAGNOSTICS .

The group actively develop and apply new electroanalytical methods capable of tracking the molecular recognition that underpins diagnostics

These have included new capacitative, shotgun, enzymic and kinetic methods of sampling molecular targets.  Some of these are exquisitely (fM) sensitive and, through integration within designed and 3D printed microfluidic configurations, generate readouts within minutes. 

We also develop new capture nanoparticle chemistries and have applied some of these with magnetically assisted microfluidics to further optimise target capture from patient blood.  We work with teams at the Oxford University NHS Trust, Molecular Oncology, Neurology, the Nuffield Department of Orthopaedics and the Nuffield Department of Surgical Sciences.
