This study investigates the suitability of poly(N-isopropylacrylamide) (pNIPAm)-based microgels

for inkjet printing, focusing on optimizing their properties for effective deposition. Key parameters, including surface

tension, viscosity, and particle size, are characterized to ensure compatibility with inkjet-printing requirements. The

addition of surfactants tune the suspensions’ properties to be in line with the requirements of inkjet printing. Jetting of

pNIPAm-based microgels on gold-coated substrates forms a cohesive drop in a range of few millimeters. Optical and

scanning electron microscopy confirm the formation of a uniform microgel layer. The optical reflectance spectroscopy

results indicate that inkjet-printed microgel-based etalons can effectively respond to changes in temperature and glucose

concentration. In-liquid atomic force microscopy demonstrates the swelling dynamics of the microgels in different

glucose concentrations, shedding light on their response dynamics.
