Mathematical Modeling for Tumor Targeting
A mathematical model is used to determine appropriate timing of an existing cancer treatment based on attaching monoclonal antibodies (mAb) to single-walled carbon nanotubes (SWNT) for breast cancer cells. The mathematical model predicts the initial dosage for intravenous injection and near-infrared (NIR) radiation emission intensity and timing as a function of the tumor volume.

Various Irradiation Times
Plasma & Lymph Flow Diagram
t = 1 min
t = 2 min
t = 3 min
The two-pore model shows how mAbs travel through the organs and tissues.
It also explains the diffusion of mAbs into the interstitium through the blood vessel wall.
Two Subcompartments Model
Immunoglobulin IgG is dispersed to the vascular and interstitial spaces through plasma flow. Their half-life is determined by the FcRn receptor in endothelial cells. This model describes the catabolic process of IgG through its internalization into the organ and tissues.

We have successfully modeled
Based on the temperature gradient of the tumor during irradiation, damage to the surrounding normal cells will be minimal. It is not desirable to have the tumor cells reach temperatures above 80°C due to bubbling of the tumor and subsequent damage to surrounding normal cells. Therefore, an irradiation time of three minutes is sufficient for eradication of tumor cells.
Due to their small size, nanosystems have been shown to overcome biological barriers, such as the blood-brain barrier, which makes them attractive for cancer therapy.

Functionalizing SWNTs with mAbs
Concentration of mAbs in the Body
The functionalization of SWNTs with mAbs serves to deliver SWNTs to the cancer site for phototherapy.
