Favorite Past Projects - Top 3

The Top-Three:

1)  J-aggregated π-Conjugated Macrocycles. A series of organic macrocycles were synthesized and self-assembled into high PL quantum yield (92%) J-aggregates. These materials exhibited strong light-matter coupling and robust ambient stability. This work was conducted at MIT. (Chan et al. J. Am. Chem. Soc. 2009, 131, 5659-5666)

2)  Metal-Catalyzed Depolymerization of Lignin. We reported a non-oxidative vanadium-catalyzed depolymerization of natural lignin. This research was done at UC Berkeley. (Chan et al. ACS Catal. 2013, 3, 1369-1377)

3)  Degradable Zwitterionic Polymers. A series of biodegradable water-soluble polycarbonates bearing zwitterionic sidechains were designed and shown to possess multifunctional properties for nanomedicine applications. This work was conducted at IBM Almaden. (Chan et al. Chem. Sci. 2014, 5, 3294-3300)

Polymeric Mixed-Micelles for Nanomedicine Applications

Some work I performed as a scientist at IBM Almaden Research Center: A degradable polymeric mixed-micelle system based on amphiphilic mPEG-b-polycarbonate diblock copolymers was developed. This mussel-inspired polymer design features catechol side chains to which the anticancer drug doxorubicin (DOX) can be covalently conjugated as pH-sensitive p-quinoneimines via a mechanism that mimics the Raper–Mason pathway of mammalian melanogenesis.
