In addition to investigating drug delivery, we have also established several high-throughput screening platforms for new drug development. These platforms provide us with an ultra-rapid automated screening capability with established libraries including various polymers, small molecules and RNAi. We have established a platform for vaccine design, such as vector-free cancer vaccine, thermostabilized oral polio vaccine and vaccine for childhood diseases. We have also been involved in the isolation of angiogenesis inhibitors and in the development of approaches for polysaccharide sequencing and drug development thereof.
