Glucose

A sample of the hydrogel turns from blue to green to red, as it takes up glucose

Thanks to a new color-changing hydrogel, there may soon be a more reliable way of continuously monitoring the blood glucose levels of both diabetics and hospital patients. If incorporated into a device such as an implanted pump, it could automatically trigger the release of insulin into the bloodstream as needed.  Read More

Researchers at the Salk Institute have found that the FGF1 protein shows promise for the d...

There are numerous research efforts underway to develop new treatments and improve the lives of people suffering type 2 diabetes, whose ranks have increased dramatically in recent decades due in large part to the so-called obesity epidemic. A new generation of safer and more effective diabetes drugs could be in the offing with researchers at the Salk Institute discovering that when mice with diet-induced diabetes were given a single injection of a protein, their blood sugar levels were restored to a healthy range for more than two days.  Read More

An illustration of the nanoscale interferometers on a biochip able to detect glucose in ar...

Two years ago, we first heard about how scientists at Rhode Island's Brown University were developing a biochip for detecting very low concentrations of glucose in saliva. Such a device could make life much easier for diabetics, as it would save them from having to perform fingerprick blood tests. At the time, it was limited to detecting glucose in water. Now, however, it's able to do so within a mixture of water, salts and select enzymes – also known as artificial saliva.  Read More

Replenishing the insulin-secreting beta cells found in the pancreas could lead to a more p...

Type 1 diabetics suffer from a lack of beta cells in the pancreas, which are responsible for insulin production. Although glucose monitoring and insulin injections allows the disease to be managed, finding a way to replenish these beta cells would offer a more permanent solution. Scientists at Gladstone Institutes in San Francisco have provided hope for just such a treatment by developing a technique to reprogram skin cells into insulin-producing beta cells.  Read More

Google's prototype blood sugar-monitoring contact lens uses a wireless chip and miniaturiz...

While we have seen the technology behind glucose-monitoring contact lenses develop over the least few years, getting them out of the lab and onto the eyes of diabetes sufferers has been a different story. With Google announcing its testing of a smart contact lens designed to measure glucose levels in tears, the search giant is looking to provide more effective management of the disease.  Read More

The nano-network that releases insulin in response to changes in blood sugar

Aside from the inconvenience of injecting insulin multiple times a day, type 1 diabetics also face health risks if the dosage level isn’t accurate. A new approach developed by US researchers has the potential to overcome both of these problems. The method relies on a network of nanoscale particles that once injected into the body, can maintain normal blood sugar levels for more than a week by releasing insulin when blood-sugar levels rise.  Read More

The tiny biosensor can calculate a person's glucose levels from tears or sweat

Despite promising developments in recent years, millions of type-1 diabetes sufferers worldwide still face the often-painful daily burden of finger sticks to test their blood glucose levels. Now researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems (IMS) have developed a biosensor that provides a non-invasive way to measure blood glucose levels and can transmit its readings wirelessly to a mobile device.  Read More

A chemical that affects the biological clock could help provide a new class of drugs to tr...

Scientists have long suspected that metabolic disorders, such as type 2 diabetes and obesity, could be linked to our circadian rhythm or biological clock. For example, laboratory mice with altered biological clocks often become obese and develop diabetes. Now biologists at UC San Diego have discovered that a chemical, which affects the activity of a key protein that regulates our biological clock, can repress the production of glucose by the liver, offering a promising new direction for the development of a new class of drugs to treat diabetes.  Read More

This silicon wafer consists of glucose fuel cells of varying sizes; the largest is 64 by 6...

A new implantable fuel cell that harvests the electrical power from the brain promises to usher in a new generation of bionic implants. Designed by MIT researchers, it uses glucose within the cerebrospinal fluid surrounding the brain to generate several hundred microwatts of power without causing any detrimental effects to the body. The technology may one day provide a whole new level of reliability and self-efficiency for all sorts of implantable brain-machine interfaces that would otherwise have to rely on external power sources. If proven harmless, the method could be used to power implants that could, among other things, help the paralyzed regain the ability to walk.  Read More

Penn State researchers have developed a way to manufacture starch fibers, which might lead...

Should you rip it off fast or slow? Researchers at Penn State may have found the elusive third, painless option. Professor Greg Ziegler and research assistant Lingyan Kong have developed a process that spins starch into fine strands, creating fibers that could be woven into low-cost toilet paper, napkins and biodegradable bandages that don't need to be ripped off at all.  Read More
