Biosensors

Researchers have used off-the-shelf components to create a sensor device that is not only cost-effective but can quickly detect 32 different pathogens and has sensitivities on par with the state-of-the-art biosensors used in pathology labs.

A novel device can detect the COVID-19 virus in one minute using just a couple of breaths of exhaled air. The device could revolutionize the testing process, especially at large-scale social gatherings like concerts or sporting events.

Intestinal glucose levels are a major indicator of gastrointestinal health, and the current method of measuring them involves putting a catheter down the patient's throat. Soon, however, a swallowable "smart pill" could do the job less intrusively.

As digital music files become increasingly popular, compact discs are likewise becoming obsolete. There may still be a use for some existing CDs, however, as the gold foil in them could be used in the production of wearable biosensors.

Researchers have developed a face mask that can detect SARS-CoV-2 in a wearer’s breath within just 90 minutes. The sensor technology can be programmed to detect any kind of virus or toxin and is small enough to be integrated into clothing fabrics.

When a patient is receiving medication, it can be difficult to determine how much of the drug is actually making its way into their bloodstream. A new subdermal "tattoo" could help, thanks to its color-changing gold nanoparticles.

New research out of Texas A&M University could lead to a simple system using a subdermal implant and a light-measuring computer peripheral to give gout patients real-time readouts of their blood urate levels, helping them avoid flare-ups.

We've recently seen a number of battery-free implantable biosensors, that are activated by the handheld device that reads them. Scientists have now created another such sensor, that's smaller than any that have come before.

Getting the correct drug dose for every patient is a challenge: too much or too little can be dangerous. A new tool developed at Stanford could keep the dose just right, using a biosensor to monitor the drug levels in a patient's bloodstream in real time, and administering extra doses as needed.

Researchers at Rice University have engineered E. coli to help detect inflammation in the colon of mice by infiltrating that microbiome and sending color signals through their feces. This could lead to self-diagnosis tests for humans ... and if your poop is blue, you should probably see a doctor.

A new graphene-based sensor has been developed that can quickly and easily detect DNA mutations associated with a range of cancers and other life-threatening illnesses. It is envisaged that the sensor will eventually be implantable, and communicate data wirelessly to mobile devices in real-time.

The skin on turkeys' heads changes color with their mood. Scientists have now copied the process by which those color changes occur, and used it to create a biosensor that could be used to detect airborne toxins.
