Scientists have developed tin oxide nanoflakes that convert near-infrared light into heat, enabling targeted, safe, and affordable photothermal cancer therapy that kills tumor cells while sparing healthy tissue, with promising results in initial tests and potential for home use in skin cancer treatment.
Scientists have developed 'molecular jackhammers' that use near-infrared light to vibrate molecules and destroy cancer cells with high efficiency, offering a non-invasive, deep-penetrating, and energy-efficient alternative to traditional therapies, showing promising results in lab and animal studies.
Scientists have developed "molecular jackhammers" using aminocyanine molecules and near-infrared light to destroy cancer cells by shaking them to death. These molecules attach to cell membranes and, when activated with light, create powerful vibrations that punch through the cell membrane, effectively destroying it. In lab tests, the process killed approximately 99% of melanoma cells, and in living animal tests on mice with melanoma, half of the animals were completely cancer-free after treatment. The use of near-infrared light allows these molecules to potentially treat tumors and cancer cells in deep tissues, offering a promising new approach in cancer treatment.
Scientists have discovered a new method to destroy cancer cells by using molecules that vibrate strongly when stimulated by near-infrared light. These "molecular jackhammers" can cause the cell membrane of cancerous cells to rupture. In lab cultures of human melanoma cells, the method had a 99% efficiency, and half of the mice with melanoma tumors became cancer-free after treatment. The molecules can be activated with near-infrared light, which can penetrate deeper into the body without damaging tissue. This study presents a new way to treat cancer using mechanical forces at the molecular scale.
Scientists at Rice University have discovered a new method to destroy cancer cells using molecules that vibrate strongly when stimulated by near-infrared light. The researchers found that these molecules, known as molecular jackhammers, can rupture the cell membrane of cancerous cells, leading to their destruction. In lab cultures of human melanoma cells, the method had a 99 percent efficiency, and half of the mice with melanoma tumors became cancer-free after treatment. The molecular jackhammers are activated by near-infrared light, which can penetrate deeper into the body without damaging tissue. This breakthrough could offer a new approach to treating cancer using mechanical forces at the molecular scale.
NASA's James Webb Space Telescope has captured a high-definition image of the supernova remnant Cassiopeia A (Cas A), revealing intricate details of the expanding shell of material from the exploded star. The near-infrared image unveils clumps of gas in bright orange and light pink, representing the inner shell of the remnant. The image also shows a hidden green feature called the "Green Monster" and a large, striated blob known as "Baby Cas A." This new era of study using Webb's instruments is providing transformational insight into the explosion and shedding light on the mysteries of the universe.
Chinese scientists from Jiangnan University have developed a way to 3D print ceramic engineering components suspended in mid-air without support structures. They use a photo-sensitive ceramic slurry that solidifies almost instantly when exposed to near-infrared light, allowing for smooth and continuous printing without the need for heating or cooling. This breakthrough could lead to more efficient and aesthetically pleasing ceramic 3D printing.
