  • Poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons are photonic materials that exhibit color based on temperature or other environmental stimuli. These materials provide a new and unique method for biosensing and other applications. Therefore it is important to understand these materials and to continue developing the materials in order to realise their full potential. This work examines the development of these materials in point-of-care (POC) diagnostics by exploring new and less expensive materials for etalon fabrication as well as examining the volume phase transition temperature of pNIPAm microgels and how it’s affected by confinement in the etalon. It was found that the metal used in fabricating the device did not have a significant impact on the optical properties of the device. Additionally it was determined that the volume phase transition temperature (VPTT) of the microgels was not affected by their confinement in the device, and a VPTT was measured at methanol concentrations where no transition was previously observed.
