MACROMOLECULAR CHEMISTRY EXPLORING the bio-materials interface

The Zhang Group

@ Northeastern University  

Research Synposis

Our group develops macromolecular systems to provide answers to important questions in biology and medicine.  Our current focus is on integrating polymer chemistry with oligonucleotides and other bioactive building blocks in order to make them better biopharmaceuticals.  Our slogan:

 

Make Oligonucleotides Great Again!
