Noor Mohammadd is currently pursuing a PhD in Defence and Security at Cranfield University, focusing on the development of compound semiconductor-based solid-state sensors for biodetection applications. He also holds an MSc in Optical Communications and Signal Processing (University of Bristol), where his research centred on magnetic–plasmonic nanoparticles for metal-enhanced fluorescence biosensing and a BSc in Electrical and Electronic Engineering (AUST), with a thesis on graphene-based one-dimensional photonic crystal structures for optoelectronic applications.

What are you working on within the Hub?

My research project aims to develop a label-free compound semiconductor-based environmental sensor to detect and characterise biological material in airborne particles. The sensor will selectively capture multiple bands of fluorescence emissions from biological particulate matter (BioPM), enabling agile, low-cost and mass-producible devices for real-time monitoring.

What is the impact of your research so far?

Current BioPM detection methods, such as single-particle UV-LIF systems, are bulky, expensive and challenging to deploy widely. My research addresses these limitations by moving this capability onto a miniaturised solid-state chip. This approach will enable mass production of highly sensitive and selective biosensors that can be deployed across domains, including public health, agriculture, environmental monitoring, security, etc. In doing so, it supports a deeper understanding of the role of biological aerosols in climate, ecosystems, human health, etc.

What has been the highlight of your research career to date?

The highlight so far has been publishing several peer-reviewed articles on optical biosensors and building on this foundation by securing a fully funded PhD within the Biodetection Technologies Hub to develop next-generation solid-state biodetection systems.

What do you enjoy doing outside of work?

Outside of research, I enjoy playing and watching football and cricket, walking and exploring new places and spending quiet time listening to music, which helps me relax and stay inspired.
