Happy Graduation

Happy graduation to Dr. Jennifer, Zeyu, Huiwen, Chutian, and Lihan. Professor Xu and the other group members wish you all the best in your future endeavors....

A Lunch Gathering in May

On May 11th, Professor Xu and the group members gathered at Flamming and Grill Buffet for a lunch together. As graduation approached, the atmosphere was tinged...

We recently published two papers in PNAS. The paper, titled “Harnessing non-Watson-Crick’s base pairing to enhance CRISPR effectors cleavage 1 activities and enable gene editing in mammalian cells,” is among the first studies to demonstrate gene editing and gene expression experiments with ZTGC RNA or DNA in prokaryotes and eukaryotes. In its second PNAS paper published in December 2023, we worked with colleagues from the University of Texas, Boston University, State University of New York, and MIT to develop mRNA COVID-19 vaccines.

We developed a lipid-based nanoscale molecular machine that achieves efficient cytosolic transport of biologics by destabilizing endo-lysosomal compartments through nanomechanical action upon light irradiation.
