Stanford Researchers Develop Noninvasive Light Delivery Method Using Ultrasound
Researchers at Stanford University have developed a novel method to deliver light to specific locations within the body noninvasively. This technique, published in Nature Materials, utilizes nanomaterials that convert ultrasound waves into precise points of light. The method allows for light-based treatments without the need for invasive procedures like tissue removal or optical fiber insertion. The research team, led by Guosong Hong, demonstrated the potential of this technology by using it to stimulate neurons in mice, causing behavioral changes. The technique could have applications in photodynamic therapy for cancer and other light-based treatments, pending further development of safer, biodegradable materials.
