About

Sisi Jia is a pioneering researcher at the intersection of DNA nanotechnology and soft materials, whose work has fundamentally advanced the design of stimuli-responsive hydrogels. Her key contributions center on creating "DNA polymerization motor gels"—intelligent materials that can autonomously change shape and perform mechanical work in response to specific biochemical triggers. In her most-cited work (2020, 25 citations), Jia developed a family of multicomponent DNA-based hydrogels with varying polymer backbones, including acrylamide-co-bis-acrylamide networks, that act as molecular motors. This breakthrough enables precise control over gel contraction and expansion by harnessing DNA polymerization reactions, opening new avenues for biosensing, smart drug delivery systems, and soft robotics. Jia’s innovative integration of DNA circuitry with polymer chemistry represents a significant leap toward programmable, life-like materials. Her research stands at the forefront of creating adaptive systems that can sense, compute, and respond to their environment, making her a rising leader in the field of DNA nanotechnology and bioinspired materials engineering.
