Plasmonics is an area of nanophotonic research involving the interactions of electromagnetic radiation and conduction
electrons on a metallic surface, resulting in enhanced optical properties. Plasmonics is the mechanism behind Surface
Plasmon Resonance (SPR.) Developing a sensor using SPR to monitor conditions within the built and natural
environment is explored in this paper.
A plasmonic sensor involves exciting surface plasmon polaritons (SPP's) present at the sensor interface by polarized
light. SPP's have sensitivities that respond rapidly to changes at the interface through the presence of analytes,
compounds or contaminants; this provides a real time label free detection method. This renders plasmonic sensors ideal
as condition monitors. Possible applications include, microbial loading within airtight buildings, soil, water and air
pollutant monitoring and structural deterioration monitoring. The advances and learning curves in the development of a
new novel sensor for deployment within the built and natural environment are presented along with initial research
findings.
