Research Focus
Cellular biomechanics; water filtration; thin film adhesion and characterization; subsurface mechano-sensing; shell adhesion; fundamental intersurface forces
About
Some of the research interests Dr. Wan specializes in are:
- Cellular biomechanics: Mechanical characterization and adhesion measurements of cancer cells, bacterial strains, drug delivery micro-capsules / liposomes, murine oocytes, biological tissues
- Water filtration: Adhesion, physisorption-chemisorption of pathogens to collector (sand) in the presence of intersurface forces and liquid flow through a porous medium
- Thin film adhesion and characterization: Mechanical reliability and lifespan of coated or encapsulated micro-/nano-devices, microelectronics parts, grapheme devices, photovoltaic panels, electrospun fiber meshes (armor protection fabrics), nano-structures
- Subsurface mechano-sensing: Mechanics of palpation to detect solid inclusion in soft tissues (e.g. breast cancer) in association with X-ray mammography, mechanical instability of lesion due to large elastic deformation and visco-rubber-elasticity
- Shell adhesion: Mechanical behavior and adhesion-detachment of natural (e.g. cornea) and artificial shells (e.g. contact lenses)
- Fundamental intersurface forces: Contact mechanics, adhesion mechanics, and colloidal science, fracture and delamination in the presence of long range surface forces and water meniscus, application in electronics and biomedical sciences
