I am studying rheology of gels under the supervision of Prof. Zhen Tong (h-index: 15). I have no publications currently. For more details of my research please visit here.
Experience
Undergraduate experience
At the last 2 years of undergraduate (2004~2005）, I participated in the experiment of multiple research groups, including:
- Artificial cornea
- Dynamic light scattering
- Polylactide synthesis
I learned how to synthesize PHEMA hydrogel in a cornea shaped module via photoinitiated radical polymerization and watch the surgery of implantation in rabbit. The result of implantation was not satisfactory. Then I also tried to remove the cornea layer from a sacrifice rabbit for endothelial cell culturing. But I did not do the cell culturing part.
I had the chance to operate a Dynamic light scattering device. I first practiced sample preparing with 300nm standard polystyrene bead, during which I knew some very basic principles of dynamic light scattering. After I can repeatedly obtained reasonable result, I was suggested to try antibody adsorption for immune detection. My advisor chose ubiquitin and its antibody. However, it was hard to tell the difference of adsorbed and non-adsorbed sample by size, while the zeta-potential data were irrelevant. But I knew how to handle sensitive bioactive samples in lab.
This is my undergraduate project. I had to find an optimized way to synthesize L-polylactide with the needed molecular weight, then I was suggested to try α-cyclodextrin inclusion complex with this polymer in order to render this biodegradable polymer chemical modifiability. Within several months of paper reading and experiment I was able to control lactide synthesis and its ring-opening polymerization reaction quiet well. However, in contrast with what was reported, I failed to obtain inclusion complex with α-cyclodextrin and polylactide. Later I also found that among dozens of polymers reported to form inclusion complexes with cyclodextrins, only a few were easily repeatable.
