It was only as a last resort that he had even tried burying microscopic magnetic dots in hardened chunks of sugar — hard candy, basically — and sending these sweet packages to colleagues in a biomedical lab.There are flexible tapes and plastics that can do the job (like using putty to pick up newsprint), but these solids can still have trouble conforming to sharp curves and corners when the print is laid back down.But, as Zabow discovered to his surprise, a simple combination of caramelized sugar and corn syrup can do the trick.Using this technique, called REFLEX (REflow-driven FLExible Xfer), microcircuit patterns could be transferred like a stencil to allow scientists or manufacturers to etch and fill the materials they need in the right places.“Wouldn’t it be nice if we could leverage some of those technologies, expanding the reach of those prints with something as simple and inexpensive as a piece of candy?”JournalScienceMethod of ResearchExperimental studySubject of ResearchNot applicableArticle TitleReflow transfer for conformal three-dimensional microprinting."
