Cutting-edge research co-led by uOttawa Faculty of Medicine Associate Professor Dr. Emilio I. Alarcón could eventually impact millions of lives with peptide-based hydrogels that will close skin wounds, deliver therapeutics to damaged heart muscle, as well as reshape and heal injured corneas. Peptides are molecules in living organisms and hydrogels are a water-based material with a gelatinous texture that have proven useful in therapeutics.and co-led by Dr. Erik Suuronen & Dr. Marc Ruel – is unique. Most hydrogels explored in tissue engineering are animal-derived and protein-based materials, but the biomaterial created by the collaborative team is supercharged by engineered peptides. This makes it more clinically translatable.Dr.
Indeed, the ability to modulate the peptide-based biomaterial is key. The uOttawa-led team’s hydrogels are designed to be customizable, making the durable material adaptable for use in a surprising range of tissues. Essentially, the two-component recipe could be adjusted to ramp up adhesivity or dial down other components depending on the part of the body needing repair.
The materials are engineered in a low-cost and scalable manner – hugely important qualities for any number of major biomedical applications. The team also devised a rapid-screening system that allowed them to significantly slash the design costs and testing timespans.
