Data underlying the paper: Inkjet-printed microgel-based etalon sensor

This study investigates the suitability of poly(N-isopropylacrylamide) (pNIPAm)-based microgelsfor inkjet printing, focusing on optimizing their properties for effective deposition. Key parameters, including surfacetension, viscosity, and particle size, are characterized to ensure compatibility with inkjet-printing requirements. Theaddition of surfactants tune the suspensions’ properties to be in line with the requirements of inkjet printing. Jetting ofpNIPAm-based microgels on gold-coated substrates forms a cohesive drop in a range of few millimeters. Optical andscanning electron microscopy confirm the formation of a uniform microgel layer. The optical reflectance spectroscopyresults indicate that inkjet-printed microgel-based etalons can effectively respond to changes in temperature and glucoseconcentration. In-liquid atomic force microscopy demonstrates the swelling dynamics of the microgels in differentglucose concentrations, shedding light on their response dynamics.
