Biosensor zymonic acid shows changes in pH value

Biosensor zymonic acid shows changes in pH value
Tumors, inflammation and circulatory disorders locally disturb the body's acid-base balance. These changes in pH value could be used for example to verify the success of cancer treatments. Up to now, however, there has been no imaging method to render such changes visible in patients. Now a team from the Technical University of Munich (TUM) has developed a pH sensor that renders pH values visible through magnetic resonance imaging (MRI) – in a non-invasive, radiation-free manner.

Wearable ECG monitor improves diagnosis of arrhythmia

Wearable ECG monitor improves diagnosis of arrhythmia
Cardiac Insight, a U.S. developer of body worn sensing devices and computational software, has announced the FDA has cleared the company’s wearable electrocardiogram (ECG) sensor, CARDEA SOLO. The device offers physicians immediate access to improved reporting and analysis of heartbeat-to-heartbeat data. The design and ease of use also encourage better patient compliance for the acquisition and recording of complete patient data.

Driving the growth of the Internet of Medical Things

Driving the growth of the Internet of Medical Things
Wearable and ingestible sensors are revolutionising the health monitoring space as the demand for quality healthcare continues to rise. Emphasis on preventive health has led to the development of prognostic sensors for applications in the medical industry. This, in turn, has led to a shift in the healthcare business model from a diagnostic one to more prognostic and preventive health and wellness.

Wearable sweat sensor can diagnose cystic fibrosis

Wearable sweat sensor can diagnose cystic fibrosis
A wristband-type wearable sweat sensor could transform diagnostics and drug evaluation for cystic fibrosis, diabetes and other diseases. The sensor collects sweat, measures its molecular constituents and then electronically transmits the results for analysis and diagnostics, according to a study led by researchers at the Stanford University School of Medicine, in collaboration with the University of California-Berkeley.

Image sensors target medical and military applications

Image sensors target medical and military applications
The portfolio of Interline Transfer Electron Multiplication CCD (IT-EMCCD) image sensors from ON Semiconductor has expanded with new options that target not only low-light industrial applications such as medical and scientific imaging, but also commercial and military applications for high-end surveillance. The new 4MP KAE-04471 uses larger 7.4 micron pixels than those found in existing IT EMCCD devices, doubling the light gathering capability of the new device and improving image quality under light starved conditions.

Smart sensor measures glucose from skin

Smart sensor measures glucose from skin
Scientists at the Institute for Basic Science in South Korea hope that a new sensor they’ve developed is a big step toward overcoming many of the challenges of measuring glucose from sweat on the skin in real-life conditions. Their device collects sweat into porous, electrochemically active electrodes and is able to use a sample down to 1 µl. There’s a multi-layer uptake mechanism that helps the sweat reach the sensors.

Image sensor enhances patient safety for digital radiography

Image sensor enhances patient safety for digital radiography
ON Semiconductor is enhancing patient safety in digital radiography with the release of a CCD image sensor that enables video imaging under reduced x-ray dosage conditions. The KAF-09001 image sensor provides the same critical imaging performance as the KAF-09000 used today for digital radiography image capture, but incorporates an improved output architecture that supports a high sensitivity video mode, facilitating patient positioning while minimising overall x-ray exposure.

Nanosensor detects DNA building blocks

Nanosensor detects DNA building blocks
Researchers at Uppsala University and in Brazil have developed a new type of nanosensor that can detect single molecules. The nanosensor, comprising a combination of two different materials, has been used to identify the different building blocks in DNA. What is really groundbreaking about this study is that it has succeeded in combining graphene, which is electrically conductive, and boron nitride, which is insulating, in the same two-dimensional material.

How does dopamine influence brain activity?

How does dopamine influence brain activity?
MIT chemical engineers have developed an extremely sensitive detector that can track single cells’ secretion of dopamine, a brain chemical responsible for carrying messages involved in reward-motivated behavior, learning, and memory. Using arrays of up to 20,000 tiny sensors, the researchers can monitor dopamine secretion of single neurons, allowing them to explore critical questions about dopamine dynamics. Until now, that has been very difficult to do.
