Nanorattles for Rapid Detection of Multiple mRNA Cancer Biomarkers
Nanorattles for Rapid Detection of Multiple mRNA Cancer Biomarkers

clockWednesday September 28, 2022

Scientists at Duke University have developed a ‘nanorattle’ system that allows for the detection of mRNA biomarkers of cancer. The tiny structures consist of gold nanospheres with a surrounding silver nanocage, forming the so-called rattle. The nanorattles are also loaded with light scattering dyes called Raman reporters. When illuminated with a laser, the rattles emit […]

Researchers at the University of California San Diego have developed a microrobot system to treat bacterial pneumonia. The microrobots consist of living algal cells that can swim very effectively in biological fluids, allowing them to navigate throughout the lungs and deliver drugs to difficult-to-reach areas. The algal cells are studded with antibiotic-loaded polymer spheres that […]
