Q&A with Sihong Wang: Breakthroughs in Bioelectronics with Hydrogel-Semiconductors
Editor: Welcome, Sihong Wang, and thank you for joining us today to discuss your team’s groundbreaking research at the University of Chicago on hydrogel-semiconductors. Can you start by explaining what a hydrogel-semiconductor is and its importance?
Sihong Wang: Thank you for having me! A hydrogel-semiconductor is an innovative material that merges the properties of hydrogels—known for their flexibility and biocompatibility—with the advanced electronic properties of semiconductors. This combination is vital for seamless integration with living tissues, making it ideal for medical implants and wearable electronics. Our research addresses a common limitation in traditional organic semiconductors, which are ofen water-repellent and thus hard to integrate with hydrophilic hydrogels.
Editor: What unique methods did your team employ to overcome these challenges?
Sihong Wang: We developed a novel polymer semiconductor with hydrophilic side chains and acrylic acid. This unique formulation allows the material to retain its hydrogel characteristics while exhibiting semiconductor properties. Consequently, our hydrogel exhibits a remarkable stretchability of up to 150% and is two to three times more deformable than traditional polymer semiconductors, making it especially suitable for dynamic biological environments.
