Laser immunotherapy (LIT) uses laser irradiation and immunological stimulation to target all types of metastases and creates a long-term tumor resistance. Glycated chitosan (GC) is the immunological stimulant used in LIT. Interestingly, GC can act as a surfactant for single-walled carbon nanotubes (SWNTs) to immunologically modify SWNTs. SWNT-GC retains the optical properties of SWNTs and the immunological functions of GC to help increase the selectivity of the laser and create a more optimal immune response. One essential aspect of understanding this immune response is knowing how laser irradiation affects cancer cells’ ability to metastasize. In this experiment, a cell migration assay was performed. A 2mm circular elastomer plugs were placed at the bottom of multi-well dishes. Pre-cancerous keratinocytes, different tumor cells, and fibroblasts were then plated separately in treated wells. Once the cells reached 100% confluence, they were irradiated by either a 980nm or 805nm wavelength laser. The goal was to determine the effects of laser irradiation and immunological stimulation on cancer cell migration in vitro, paying the way to understand the mechanism of LIT in treating metastatic tumors in cancer patients.
