This group's focus lies in synthesizing functional resins which can be used in two-photon lithography and 3D printing to fabricate cross-linked architectures with a variety of chemical functionalities, which range from surface functional ligands (i. e. thiols, N-BOC, octane, aromatics, DNA, pharmaceutical compounds, etc.) to shape-memory polymers, whose shape can be programmed at a particular temperature and then mechanically altered, to DNA origami that can be used for large-area nano-patterning.
This architectural versatility renders these 3D polymer structures useful for many technological applications, including drug delivery and tissue engineering. Synthesizing and architecting these meta-materials with the right chemical functionality on the surface and/or in the volume presents a significant challenge. We are developing such architected, chemically-functionalized 3D meta-materials that are responsive to external stimuli and are exploring the specific role that architecture plays on their behavior and how to harness these effects to engineer new multi-functional devices.
