Optimizing piezoelectric inkjet printing of silica sols for biosensor production

The inkjet printing of biocompatible silica sols has gained popularity, both for biosensor production and development of holographic devices. However, there still remain significant issues related to premature clogging of inkjet printheads when printing aqueous silica sols. To better understand the causes of clogging of piezoelectric inkjet nozzles, printing studies were coupled with studies of colloidal stability along with silica deposition …
