Overview

An aerosol is a suspension of particles or droplets in the air and includes airborne dusts, mists, fumes or smoke. The suspended particles maintain their physical properties of their solid or liquid state, but they behave like a vapour. Bioaerosols are airborne particles of biological origin, including bacteria, viruses, fungi, pollen and toxins. Depending on particle size, composition, shape and concentration, aerosol and bioaerosol particles can cause adverse health effects in workers. Adverse health effects can be either short or long term. Safety hazards may include fire or explosions.

Currently, technology for real-time detection and identification of bioaerosols is not fully developed, and monitoring systems are not widely utilised. The E3 - Future Biodetection Technologies Research Hub will target the gaps in knowledge about the characteristics and dynamics of bioaerosols in outdoor and indoor environments and their impact on health, climate and ecosystems.

This PhD project aims to develop a proof-of-concept for a portable BioPM sensor exploiting some novel physical phenomenon where electron-photon interaction could be exploited in some solid-state device platforms to mimic this interaction. The absorb photons could give off their energy in several ways including to electrons inside the semiconductor device that would in turn could be detected. In this project we will design and fabricate several novel sensor devices and detect at least three bands out of 16 wavelength bands of fluorescence measurement, from 298 – 735nm, as a proof of concept.

Project Focus:

Smart and agile environmental sensor is a dream of every environmental researcher and professional because it does not exist.  The aim is to establish a foundation to transform the detection of BioPM – Imagine a BioPM chip in every home and every car would transform our view on the environment – just like energy efficient climate control in most air-conditioning systems is due to carbon dioxide sensor on a chip. The main aspects of this research will need to consider, after any positive outcome of project, a best route to commercialisation but main aim is to focus in delivering a successful proof of concept.

Objectives:

• Develop and deliver proof-of-concept demonstrator sensor technologies,
• Develop optical-fluorescence spectral libraries for a chip-based system relevant to multichannel UV-LIF measurements.
