Semiconductor quantum dots have emerged as a highly promising material for biomedical sensing applications to overcome a wide range of challenges. By pairing quantum dots with highly sensitive photonic metrology instrumentation, small changes within the measurand properties, or analytes of interest, can be quantified in response to a stimulus. In this project, the student will develop bespoke, spray-on luminescent sensors for use within analytical measurements. Using a range of semiconductor quantum dots and a novel aerosol jet printing (AJP) “spray-on” deposition procedure, the student will create luminescent sensors for the detection of specific analytes of interest within liquids. By combining this approach with spectrometers, semiconductor photodetectors and single-photon measurement instrumentation, low level analyte detection will be explored. This will ultimately lead to the development of a bespoke and novel approach for applications including medical, neuroscience, environmental monitoring, and energy. The student will be supported in their research by a large team of experienced researchers and PhD students from the System Sensor Group and will have access to a fully equipped metrology laboratory and AJP deposition system. Students will be expected to present their findings orally at a research day in York in September 2024.
