Electrophoretic Focusing and Navigation for Intranasal Target Drug Delivery

X. Si[1]
[1]Calvin College, Grand Rapids, MI, USA

Direct nose-to-brain drug delivery circumvents the blood-brain-barrier and has multiple advantages over intravenous delivery. However, its application is limited by the extremely low delivery efficiency to the olfactory region. This study evaluated the feasibility of targeted drug ... Read More

Singlet Oxygen Modeling for PDT Incorporating Local Vascular Oxygen Diffusion

T. C. Zhu[1], B. Liu[1]
[1]University of Pennsylvania, Philadelphia, PA, USA

Singlet oxygen (1O2) is the major cytotoxic agent that kills cells during photodynamic therapy (PDT). Based on a previously-developed model, the distance-dependent reacted 1O2 can be numerically calculated using finite-element method. We improved the model to include microscopic kinetic ...
