Engineers have devised a method that uses nanoparticles, called gold nanostars, to help identify early biomarkers of cancer without the need for the elaborate, time-consuming, and expensive processes required by current technologies.
Researchers have developed a method that combines high-precision protein measurement with sticky nanoparticles to capture and analyze a common marker of heart disease and to reveal details that were previously inaccessible.
In experiments in rats and mice, researchers have reported the successful use of nanoparticles to deliver gene therapy for wet age-related macular degeneration – an eye disease characterized by abnormal blood vessel growth that damages the retina.
By folding DNA into a virus-like structure, researchers have designed HIV-like nanoparticles that provoke a strong immune response from human immune cells grown in a lab dish. Such nanoparticles might eventually be used as an HIV vaccine.
