"Soft Materials Innovation for Health and Sustainability"

 

 

Abstract:

Biopolymers (e.g., proteins, nucleic acids, carbohydrates, and lipids) and water are the major components that constitute most living species on the earth, ranging from animals, plants, and fungi to bacteria. Polymers are also pervasive and indispensable in almost every aspect of our daily life, ranging from food, clothing, housing, and medicine to transportation, communication, and entertainment. Furthermore, over 6% of global electricity generated from coal is used to make plastics, and microplastics are already ubiquitous in global biosphere. Intrigued by their ubiquity and impacts, MIT Zhao Lab is focused on the study and development of soft materials and systems, mainly constituted of polymers and water.

In this talk, I will first discuss a general strategy to design new soft materials and systems that possess extreme physical, chemical, and biological properties – via bioinspired and rational design of unconventional polymer networks. Then, I will illustrate the impacts of soft materials innovation on health and sustainability with examples: i). bioadhesives capable of instant strong adhesion on diverse wet dynamic tissues for future wound sealing, hemostasis, bioelectronics, and wearable devices; ii). magnetic soft robots capable of teleoperated and autonomous neurovascular surgery for remotely treating stroke which is globally #1 cause of long-term disability and #2 cause of death; iii). hydrogels capable of solar-driven atmospheric water harvesting that can potentially address the worldwide lack of safe drinking water for 2 billion people. I will conclude the talk with a vision on the future development and impacts of soft materials and systems – added by and synergized with technologies such as artificial intelligence, synthetic biology, and precision medicine.
