WHAT WE DO
The NanoBioengineering Laboratory focuses on fundamental understanding of biotansport issues for the brain and diagnostic systems, and develop nanotechnology-based approaches to better understand the brain and revolutionize point-of-care infectious disease diagnosis. Recent efforts focus on the laser-plasmonic nanoparticle interactions and its effects at the interface between biological systems and nanomaterials. Specifically, experimental techniques and methods have been developed to understand the effects of nanoparticle plasmonic heating on proteins and lipids immediately next to the nanoparticle. This has led to new enabling tools for optical protein manipulation and molecular uncaging for the brain, and innovative diagnostic methods.
The burden of brain diseases has increased substantially over the last 25 years and will continue to grow in coming decades. Our brain is a complex system with blood flow and vessels that supply nutrients but restricts passage of most other molecules, and neuronal network that is maintained and modulated by the extracellular “chemical connectome”. The central question we pursue is: how does the molecular transport in the brain affect brain activity and function? By engineering new nanotechnologies, our long-term goal is to better understand the molecular transport and improve the treatment of brain diseases.
RESPIRATORY INFECTIOUS DISEASES DIAGNOSIS
Viral respiratory tract infection (VRTI) is the most common illness in humans and non-influenza-related VTRI costs over $40 billion annually in the United States alone. This includes respiratory syncytial virus (RSV), which is among the leading causes of pediatric death secondary to pneumonia worldwide and to date there is no available effective vaccine or antiviral therapy. Early and point-of-care (POC) diagnosis of RSV is critical to isolate infection reservoirs and inform treatment decisions. The central question we pursue is: how to diagnose infections with high sensitivity and specificity in the simplest and cost-effective way? By engineering novel and improving current POC diagnostic tests, our long-term goal is to transform the current practice of infectious disease diagnosis.
