What are gold nanorods used for in this study?
Gold nanorods are used to induce localized heating in tumors when exposed to near-infrared light.
How is the internal tumor temperature monitored?
A temperature probe is inserted into the tumor to provide real-time temperature readings during treatment.
What is the target temperature range for hyperthermia?
The target hyperthermic range is between 42 to 48 degrees Celsius.
How often should tumor measurements be taken?
Tumor measurements should begin daily starting around day seven post-cancer cell injection.
What precautions are taken to protect healthy tissue?
Aloe vera gel is applied to the tumor surface to minimize the risk of thermal injury during treatment.
What is the significance of using near-infrared light?
Near-infrared light is effective for activating gold nanorods to induce localized heating in tumors.
