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 […]

Algae-Based Microrobots Deliver Antibiotics within Lungs
Algae-Based Microrobots Deliver Antibiotics within Lungs

clockWednesday September 28, 2022

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 […]

Face Mask Detects Respiratory Viruses, Alerts User

clockThursday September 22, 2022

Scientists at Shanghai Tongji University in China have created a face mask that can alert the wearer to the presence of respiratory viruses in the surrounding environment, including the viruses behind COVID-19 and influenza. The mask includes aptamers, which are short sequences of DNA or RNA that can bind to protein targets. When viral particles […]

Smartphone Camera Measures Blood Oxygen
Smartphone Camera Measures Blood Oxygen

clockWednesday September 21, 2022

At the University of Washington a research team has developed a smartphone system that can measure blood oxygen levels. The technology uses the camera and flash of the phone to take the measurement, and the system is so easy to use that it may be well suited for at-home use. A person presses their finger […]
