Nanoparticle Skin Patch Monitors Tumor Size During Cancer Care | The nanoparticle-infused skin patch can send its data to a smartphone, making tumor monitoring even easier.
Medical researchers and chemical engineers have developed a new nanoparticle-infused wearable patch that can provide continuous monitoring of tumors under the skin.
Medical researchers and chemical engineers at Taiwan’s National Tsing Hua University have developed a new wearable patch that can provide continuous monitoring of tumors under the skin. The patch, which consists of a thermoplastic polyurethane (TPU) film embedded with hafnium oxide (HfO 2) nanoparticles, can also transmit real-time data to a smartphone to support the tracking of tumor growth and regression. “The wearable TPU-HfO 2 DE [dielectric elastomer] strain sensor developed demonstrates exceptional precision in measurements, maintaining accuracy even when dealing with minute tumor volumes, as evidenced by a significantly lower error percentage (averaging around 5 to 10%) compared to those obtained by the caliper (ranging from approximately 10 to 20%) in in vivo experiments,” the researchers wrote.
