New Nanotech Speeds Up Foodborne Pathogen Detection in Under Four Hours

16 hours ago | azosensors.com | Bethan Davies |Noopur Jain

Reviewed by Bethan DaviesA new study introduces glycan-coated magnetic nanoparticles (gMNPs) as a faster, more efficient tool for detecting harmful pathogens in food. Published in Food Quality and Safety, the research responds to an urgent need for quicker pathogen detection methods, crucial for minimizing health risks and the economic impact of foodborne contamination.
NASA to Launch First Space-Based Quantum Gravity Sensor

1 day ago | azosensors.com | Bethan Davies |Noopur Jain

Reviewed by Bethan DaviesNASA has announced a mission to build and launch the first quantum sensor designed to measure gravity from space. The Quantum Gravity Gradiometer Pathfinder (QGGPf) is set to push the boundaries of precision in gravitational measurement—an advancement that could influence everything from resource management and navigation to our understanding of fundamental physics.
Drone-Mounted Hyperspectral Sensors Track Gene Expression in the Field

1 day ago | azosensors.com | Bethan Davies |Noopur Jain

Reviewed by Bethan DaviesResearchers have developed hyperspectral reporters (HSRs)—a new type of genetic tool that allows scientists to detect gene expression in living organisms from as far as 90 meters away using drone- or satellite-mounted imaging systems. This innovation hinges on hyperspectral imaging (HSI), a technology that captures a broad spectrum of light for every pixel in a scene.
Can You Really Trust What’s on Your Plate? How Sensor Tech is Catching Food Fraudsters

1 week ago | azosensors.com | Bethan Davies |Ankit Singh

Reviewed by Bethan DaviesFood fraud is more than a labeling issue—it’s a global challenge that affects consumer safety, brand trust, and the integrity of supply chains. Whether it’s watered-down olive oil, misrepresented seafood, or milk contaminated with melamine, these practices are often hard to detect and costly to address.
Comprehensive Radiation Detection with a Portable Device

1 week ago | azosensors.com | Laura Thomson

In cooperation with the Finnish Radiation and Nuclear Safety Authority (STUK), the University of Jyväskylä has created an innovative type of portable multi-purpose radiation detector that can detect all forms of ionizing radiation, according to a study published in Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment.
New Handheld Device Could Make Heart Valve Disease Detection Easier for Everyone

1 week ago | azosensors.com | Bethan Davies |Noopur Jain

Reviewed by Bethan DaviesA new study published in the IEEE Journal of Biomedical and Health Informatics introduces something that could be a real game-changer in heart health: a simple, handheld device that lets just about anyone record heart sounds—no medical degree required. Why This MattersHeart valve disease (VHD) is a big deal. If it goes undetected, the consequences can be more serious than some cancers. The problem is that diagnosing VHD isn’t easy.
Tiny Brain Sensor Could Eliminate Surgery for TBI Monitoring

1 week ago | azosensors.com | Bethan Davies

Georgia Tech researchers have developed a tiny, flexible brain pressure sensor—smaller than a dime—that can be implanted without surgery, offering a safer way to monitor traumatic brain injuries. A car accident, football game, or even a bad fall can result in a serious—or even fatal—head injury. Each year, traumatic brain injuries (TBI) lead to roughly half a million permanent disabilities and 50,000 deaths.
These Wearables Could Be the Key to Surviving Long Space Missions

1 week ago | azosensors.com | Bethan Davies

A recent breakthrough in flexible wearable technologies is reshaping how astronauts' health is monitored during space missions. A new review published in Wearable Electronics explores the current applications and ongoing challenges of these systems in aerospace medicine. As human space exploration moves toward longer-duration missions, the need for real-time monitoring of astronauts’ physical and psychological health is becoming increasingly important.
NASA’s New Radar Health Monitor Might Be the Most Effortless Way to Track Vitals Yet

1 week ago | azosensors.com | Bethan Davies |Noopur Jain

Reviewed by Bethan DaviesNASA has adapted its advanced sensing technology—originally developed for space exploration—to address a pressing healthcare need here on Earth: continuous, contactless monitoring of vital signs. In partnership with Advanced TeleSensors, Inc., NASA engineers have developed the Cardi/o Monitor, a device that uses radar-based technology to track heart rate and respiration without requiring physical contact.
INL Unveils 3D Brain Model with Quantum Sensors for Studying Neurodegenerative Diseases

1 week ago | azosensors.com | Bethan Davies

A recent study from the International Iberian Nanotechnology Laboratory (INL) has successfully integrated two advanced 3D tissue engineering approaches—3D polymeric scaffolds and 3D neuronal spheroids—to create a highly sophisticated model for studying neuronal behavior and disease. This interdisciplinary collaboration between biomedical engineers, physicists, and neuroscientists led to the development of a smart polymeric scaffold embedded with fluorescent nanodiamonds.
