Drug Delivery

The research of Drug Delivery in Wang Lab focuses on designing novel drug delivery systems targeting different tissues and organs for various diseases. Dr. Wang’s early publications directly addressed the research and engineering of biodegradable and biocompatible drug-delivery materials. He explored the application of natural polymers to make drug-loaded fibers for wound healing [1, 2, 3]. The drug-loaded fibers can provide a sustained release to the wound and accelerate the healing process. Alginate and Chitosan composite membrane materials have provided sustained drug release for pharmaceutics [4, 5]. Dr. Wang has worked with colleagues to develop solid-lipid nanoparticles to treat rheumatoid arthritis [6], diabetes [7, 8], and liver disease [9]. In addition, Dr. Wang has developed several biomimetic and bio-responsive drug delivery systems for cancer therapy[10]. These intelligent systems could be used to treat breast cancer [11-14], Leukemia [15-18], Melanoma [19], and colorectal cancer [20]. Dr. Wang also works on developing specific targeting drug delivery systems for regenerative medicine [21], diabetes treatment [22], immunotherapy [23, 24], and neurodegenerative disorders [25]. In 2021, Dr. Wang reviewed the most recent advancements of PEGylated methods of nanoparticles and the related techniques to detect PEG coverage density and thickness on the particle’s surface [26]. The molecular weight (MW) and coverage density of PEG coating on nanoparticles’ surfaces are discussed to explain the effects on nanoparticles’ biophysical and chemical properties.
