Hydrogels for therapeutic angiogenesis


The purpose of our research is to create biomimetic and programmable materials for drug delivery, tissue regeneration and clinical diagnosis.


The objective of this project is to train undergraduate students to synthesize aptamer-functionalized hydrogels that can release multiple growth factors sequentially. The hypothesis is that multiple aptamers can release growth factors sequentially from hydrogels when triggered by aptamer-specific complementary oligonucleotides and therefore this growth factor release pattern would promote more healthy angiogenesis in the body. In this project, we will study a new hydrogel.


The hydrogels will be synthesized with free radical polymerization. The hydrogels will be characterized using scanning electronic microscope. The release kinetics will be examined with ELISA. The bioactivity will be studied using the tube formation assay and the chick embryo chorioallantoic membrane assay.

Data to be collected

Data to be acquired will include the results from numerous assays such as scanning electron microscopy (SEM), gel electrophoresis, ELISA, and surface plasmon resonance.


The training of the students will be analyzed by testing whether they are able to synthesize the hydrogels and examine the functionalities of the hydrogels with expected quality independently.
