New Immunosensor Paves Way to Rapid POC Testing for COVID-19 and Emerging Infectious Diseases

Researchers have developed a new immunosensor based on Quenchbody technology that shows great potential as a fast, inexpensive, and convenient tool to detect SARS-CoV-2. This highly efficient diagnostic approach will be useful not only for point-of-care testing, but also for high-throughput epidemiological studies of COVID-19 and other emerging infectious diseases.

Photon-Counting CT Shows More Post-COVID-19 Lung Damage

A new study has shown that photon-counting detector (PCD) CT technology outperforms conventional CT in detecting subtle damage in the lungs of patients with persistent symptoms of COVID-19. The technology could lead the way to earlier treatment and better outcomes for the growing number of people with COVID-related lung damage, according to researchers. More...

Low-Cost System Detects SARS-CoV-2 Virus in Hospital Air Using High-Tech Bubbles

Scientists have shown that they can detect the SARS-CoV-2 virus in the air by using a nanotechnology-packed bubble that spills its chemical contents like a broken piñata when encountering the virus. Such a detector could be positioned on a wall or ceiling, or in an air duct, where there’s constant air movement, to alert occupants immediately when even a trace level of the virus is present.

New Model Detects Long-COVID’s Effects Using Simple, 2D Chest X-Rays

Researchers have developed what is called a contrastive learning model that “learns” from composite 2D images constructed from 3D CT images to detect compromised lung function in long-COVID patients. More...

Lung MRI Shows Lasting Damage in Children and Teens After COVID

A new study has revealed that children and adolescents who have either recovered from COVID-19 or have long COVID show persistent lung damage on MRI. More...
