Research Interest

My research mainly focuses on the development of stimuli-responsive dendrimer nanocarriers for targeted delivery of small-molecule therapeutics and biomacromolecule to malignant tumors and infections. (i) Local Delivery of Dendrimer Nanomedicines for Lung Cancer Treatment/Lung Metastasis Prophylaxis -Engineered stimuli-responsive dendrimer-anticancer agent nanoconjugates to achieve cancer tissue targeting, promote intracellular drug delivery to specific organelles, and overcome drug resistance. -Pulmonary administration of the nanoconjugates to increase drug accumulation in lung tumors, while minimize systemic toxicity. ? Validated in vitro/in vivo stimuli responsiveness of dendrimer nanomedicnes. -Evaluated the antitumor activity of the nanoconjugates on a variety of primary lung cancers and metastatic cancers to lungs, systemic and local toxicity, and in vitro/in vivo fate of dendrimer nanoconjugates (i.e. cellular interaction, pharmacokinetics, biodistribution). (ii) Oral Inhalation Formulations of Dendrimeric Nanomedicines for Non-invasive Pulmonary Delivery -Developed portable aerosol formulations of dendrimer-based nanomedicines in metered dose inhaler and dry powder inhaler. -Optimized drug dosing, aerosol performance, and long-shelf stability (iii) Targeted Chemotherapeutic Delivery with Dendrimer Nanocarriers for Cancer Treatment -Designed long-time circulatory dendrimer nanocarriers that target therapeutics to malignant tumors. -Evaluated the antitumor activity and in vivo fate of targeted dendrimer-based nanomedicines (e.g. pharmacokinetics, biodistribution, and toxicity). -The developed drug delivery system are being tested in breast cancer and bone metastasis models. (iv) Stimuli-Responsive Dendrimer Nanocarrier as a Cancer Vaccine Delivery Platform -Engineered enzyme-sensitive dendrimer-peptide nanovaccine for enhanced immune response -Improved tumor inhibition have been validated in two cancer model human papillomavirus-induced cervical cancer and lung metastasis from melanoma
