Dr Ian Sandall MPhys, PhD

Ian is investigating the use optical semiconductor devices (Lasers, LEDs and Photo detectors) to analyse biological samples. Techniques he is interested in include fluorescence, absorption and interference spectroscopy.
The use of semiconductor devices to perform these analysis techniques offers the potential to greatly reduce the size and complexity of many current “bench top” systems used and allow “lab-on-a-chip” systems to be realized.
Lab-on-a-chip systems offer the potential to achieve compact, portable and cost effective systems that can be used for rapid diagnostics at the point of care, even in potentially remote or hazardous locations.

Ian has an active interest in developing novel semiconductor materials which can be utilized in a variety of optical devices. He has worked on quantum well and quantum dot based devices for a range of applications including; telecommunications, security, defence, medical and astronomical observations.

Ian has extensive experience and expertise in designing and characterizing optoelectronic devices and has worked with a range of novel materials including; dilute nitrogen and bismuth containing alloys, antimony based alloys for photodetectors and nanowires.
