Faculty seminar - Magnetic hydrogel for cancer study and wound healing
Magnetic hydrogels are materials containing magnetic microparticles which help transduce magnetic fields into mechanical forces. In the presence of a static magnet, the stiffness of magnetic hydrogels can be altered to investigate the reversible effects of matrix softening and stiffening on cellular behaviours. Here, I will describe how we exploit this unique feature of our material for cancer study.
The World Health Organization estimates that 10% of the world’s population suffers from diabetes, and diabetic patients has a 15-25% lifetime risk of getting diabetic foot ulcers. Every 20s, there is a lower extremity amputation worldwide. In the second half of my talk, I will describe the use of magnetic hydrogel for mechanical stimulation of cells to synergistically accelerate diabetic wound healing.
Andy Tay graduated in 2014 from NUS with a First-Class Honours in Biomedical Engineering. He later headed to the University of California, Los Angeles for his PhD studies and graduated in 2017 as the recipient of the Harry M Showman Commencement Award. Andy next received his postdoctoral training at Stanford University before heading to Imperial College London as an 1851 Royal Commission Brunel Research Fellow. He is currently a Presidential Young Professor in NUS.
