Gold Nanoparticles as a Cancer Treatment By: Celia Dunn
Background of Cancer Treatments • Egypt 3000B.C. • 1761 – First Autopsy • 19th Century- Birth of Oncology • In 1915, Scientists at Tokyo University induced cancer in lab animals for the first time • Current Cancer Treatments Include: Surgery, Radiation, Chemotherapy, Hormone Therapy, Immune Therapy, and Targeted Therapy
Statistics • Over 50 Different Types of Cancer • Over 12 Million People Impacted Globally • Almost 2 Million Diagnoses in the U.S. Alone – 35% Death Rate
The Problem • Tumors can get wrapped around other organs and bone which can make them inoperable and require extensive treatments which are extremely harsh on healthy cells.
Two Experiments 1- Swinburne University of Technology 2- Rice University
Swinburne University of Technology • Used Gold Nanoparticles to Amplify Hypothermia in Cells
How it Works 1- Gold Nanoparticles Infect Cancer Cells 2- High Heat FLMS Laser Pulses are Sent into Tumor Site and Hit Gold Nanoparticles 3- Gold Nanoparticles Heat up and Cause Major Damage in Cells - HYPERTHERMIA 4- Cell Death
Rice University • Used Gold Nanoparticlesto Develop“quadrapeutics”
“Quadrapeutics” • 1. LASER PULSE • 2. X-RAYS (3-6 PERCENT OF A TYPICAL RADIATION DOSE) • 3. GOLD NANOPARTICLES • 4. DRUGS
How it works • 1. Low Dose of Chemotherapy Drug – Tags Cancer Cells • 2. Inject Gold Nanoparticles • 3. Low Heat Near-Infrared Laser Pulse • Nano Particles Turn into Nanobubbles • 4. Low Dose of Radiation • RESULTS: Intracellular Explosions • 17 Times More Efficient than Chemoradiation Therapy
SUCESS • SUCCESFULLY REMOVED TUMORS IN MICE
DIFferences • 1- Swinburne University of Technology • Relies on high heat lasers • Does not use Drugs • Kills More Healthy Cells than the Rice University Experiment • 2- Rice University • Uses Low Heat Lasers • Uses Drugs • Kills Less Healthy Cells than the Swinburne University of Technology Experiment
RISKS • Could Kill too Many Healthy Cells • Cause Major Tissue Damage to Organs
Future • MOVE INTO CLINICAL TRIALS • CURE FOR INOPERABLE TUMORS • CURE FOR HARD TO TREAT CANCERS • LUNG, BRAIN, PROSTATE, ETC..
