Abstract: Abstract Molecularly imprinted polymers have been the subject of intense research for several decades in both academic and industrial settings. In this paper, we introduce a novel microwave-assisted sol–gel method for molecular imprinting of silica microspheres. The microspheres were characterized, and their adsorption of imprint and non-imprint molecules was investigated. The dye molecules methyl orange and ethyl orange were used as templates. Good molecular imprinting was observed as evaluated by the re-adsorption of dye into the silica matrix followed by the removal of dye from the supernatant solution. We describe a novel microwave-assisted sol-gel method for molecular imprinting of silica microspheres. The microspheres were smooth and well dispersed. The adsorption capacity, relative adsorption capacity, specific adsorption capacity, and different effects for imprinted and non-imprinted microspheres were determined for dye molecules as the molecular imprints. This synthetic methodology has promise for use in preparation of molecularly imprinted solids
