Hi Bill, labs are using inkjet printers now to 'spray' fine even coats of living cells and other materials such as solar cell components. With gelatin out of the equation do you think inkjet technology could be used with your formula to make precision coatings? People shouldn't think in terms of the emulsion having an inkjet pattern, since it is liquid it would settle and become uniform after the spraying. If so this could be a huge breakthrough in small scale production..
