This novel hydrogel-type biomaterial can heal organ damages.

It opens the door to applications like drug delivery, tissue engineering, and the creation of model tissues for drug screening.

 

Nowadays, Hydrogels have been playing a major role in medical science and bio fabrication.

They can heal, repair, duplicate, replicate and even accelerate cell growth in the human body. 

 

So taking advantage, scientists from McGill University integrated concepts of biology, physics, chemistry, and engineering with the goal of making a regenerative medicine or treatment.

 

Finally, they created a revolutionizing biomaterial in the form of a ‘Hydrogel’ that can be injected into the human body. By taking individuals’ cells, the purpose of this thing is to reserve space for cells and to grow upon them.

“People recovering from heart damage often face a long and tricky journey. Healing is challenging because of the constant movement tissues must withstand as the heart beats. The same is true for vocal cords. Until now there was no injectable material strong enough for the job,” said Guang Bao, a candidate in the mechanical engineering department of the Universe.

The research team was led by Professor Luc Mongeau and assistant professor Jianyu Li. During the research, they tested their innovative hydrogel on a biomechanical simulation. The intention was to recreate the behavior of a human vocal cord.

Bao said that “We were incredibly excited to see it worked perfectly in our test. Before our work, no injectable hydrogels possessed both high porosity and toughness at the same time. To solve this issue, we introduced a pore-forming polymer to our formula.”

 

This novel method of treatment could be able to save millions of lives from heart failure, larynx damage, etc.

Moreover, these materials can be used in making model tissues in the laboratory for future medicinal research purposes. 

This way, we can also reduce experimenting on humans and animals.
