Abstract: The present disclosure relates to an Inkjet printing process that comprises inkjet printing an inkjet ink composition onto a substrate to form a printed inkjet ink layer. The inkjet ink composition comprises a colorant, a curable polyurethane dispersion, a photoinitiator and water, wherein the amount of curable polyurethane dispersed in the inkjet ink composition is 0.1 to 30 weight %. A radiation-curable overcoat composition is applied over the printed inkjet ink layer as an overcoat layer. The overcoat composition comprises a curable polyurethane dispersion, a photoinitiator and water. The printed inkjet ink layer is then cured on the substrate by exposing both the overcoat layer and inkjet ink layer on the substrate to radiation.

Abstract: A scattering spectroscopy nanosensor includes a nanoscale-patterned sensing substrate to produce an optical scattering response signal indicative of a presence of an analyte when interrogated by an optical stimulus. The scattering spectroscopy nanosensor further includes a protective covering to cover and protect the nanoscale-patterned sensing substrate. The protective covering is to be selectably removed by exposure to an optical beam incident on the protective covering. The protective covering is to prevent the analyte from interacting with the nanoscale-patterned sensing substrate prior to being removed.
