Scientists at Nanyang Technological University in Singapore announced a new class of light-activated compounds called aryl diazirine photoinitiators on October 23. These compounds start polymerisation when illuminated, turning liquid resin into solid material. The team, led by materials scientist Terry Steele, reported that the compounds were non-toxic to human cells in the study.
Some of the compounds dissolve in water and are liquid at room temperature. Nitrogen released during curing can be adjusted to counter resin shrinkage. The researchers used soybean-oil-based resin to demonstrate water-tight seals and 3D-printed microfluidic channels, or tiny channels for handling fluids. They also demonstrated a skin adhesive that stretched beyond three-and-a-half times its original length without damaging the skin underneath.
The paper appeared online on October 16, ahead of the university announcement. Lead author Naziruddin Ali said the next step was translating the laboratory findings into industrial-scale manufacturing.
