This video walks through the process of preparing Teflon-patterned paper arrays- beginning with depositing sugar drops to protect the 96 "zones" (the outlines were previously printed with a solid ink printer), followed by spraying liquid Teflon, followed by a washing step.

In this clip, the hand-cranked prototype that won the SPARK competition "reads" the holes in a punch card passing under its pin-covered mechanism. When a pin slots into a hole, the device pushes colored fluid through a corresponding channel on the device's microfluidic chip. In this way, the tiny machine can mix together nanoliter quantities of chemicals and carry out safely contained, programmed reactions.

Expiration and sell-by dates on foods and beverages don’t always take into account how products are stored during the journey from farm to supermarket. In this video, researchers in China show off gelatin-based materials that might one day be attached to the outside of a food or beverage to report the product’s age and how long it’s been outside of refrigeration. The low-cost indicators go from red to orange to green as a perishable’s quality degrades.
