Researchers invent a better way to coat liquid drops

Tuesday, October 22, 2019

Technology invented by researchers at Waterloo Engineering could improve the targeted delivery of drugs within the human body.

The researchers developed a faster, cheaper way of coating and protecting liquid drops as they fall through a thin layer of liquid shell, a process that uses gravity and other natural forces.

Sirshendu Misra, a PhD student at Waterloo Engineering, works on encapsulation research in the Micro Nano-Scale Transport Lab.

The shell, once hardened by exposure to ultraviolet light, is designed to dissolve and release its contents when required - after reaching a particular area of the body, for instance.

“It is a very simple technique that requires almost no energy – and it is extremely rapid,” said Sushanta Mitra, an engineering professor and executive director of the Waterloo Institute for Nanotechnology. “Encapsulation takes place in milliseconds.”
