Our Post-Truth Culture: Institutional and Individual Consequences August 2, 2016TweetThis presidential election has become the perfect storm of “post-truth” politics and racism. Nanoengineers at the University of California, San Diego have tested a temporary tattoo that both extracts and measures the level of glucose in the fluid in between skin cells.
The sensor was developed and tested by graduate student Amay Bandodkar and colleagues in Professor Joseph Wang's laboratory at the NanoEngineering Department and the Center for Wearable Sensors at the Jacobs School of Engineering at UC San Diego. At the moment, the tattoo doesn't provide the kind of numerical readout that a patient would need to monitor his or her own glucose.
The research team is also working on ways to make the tattoo last longer while keeping its overall cost down, he noted. The Center "envisions using these glucose tattoo sensors to continuously monitor glucose levels of large populations as a function of their dietary habits," Bandodkar said.
People with diabetes often must test their glucose levels multiple times per day, using devices that use a tiny needle to extract a small blood sample from a fingertip. In their report in the journal Analytical Chemistry, Wang and his co-workers describe their flexible device, which consists of carefully patterned electrodes printed on temporary tattoo paper. Wang and colleagues applied the tattoo to seven men and women between the ages of 20 and 40 with no history of diabetes. To test how well the tattoo picked up the spike in glucose levels after a meal, the volunteers ate a carb-rich meal of a sandwich and soda in the lab.
The researchers say the device could be used to measure other important chemicals such as lactate, a metabolite analyzed in athletes to monitor their fitness. Abstract We present a proof-of-concept demonstration of an all-printed temporary tattoo-based glucose sensor for noninvasive glycemic monitoring. A device that uses a modified iPhone to help regulate the blood sugar of people with type 1 diabetes appears to work better than an insulin pump, researchers say. New research suggests that people who arrive at hospital emergency departments with acute heart failure should have their blood sugar levels checked on arrival.


Research at ANSTO has helped to reveal insights into a molecular mechanism for harvesting light in extreme conditions. A new study, published in Biochemistry this week, examines the biomechanics of sugar-seeking proteins.
Cancer cells are more dependent on a cellular garbage disposal unita€”the proteasomea€”than healthy cells, and cancer therapies take advantage of this dependency. Many molecules have a chemical structure that is "chiral" - they come in two forms, each with an arrangement of atoms that are mirror images of each other. Researchers used super-X-ray vision to peer beneath the surface of a portrait by impressionist Edgar Degas and gaze upon the model whose likeness he painted over nearly 140 years ago, they reported Thursday. Turning carbon dioxide into stored energy sounds like science fiction: researchers have long tried to find simple ways to convert this greenhouse gas into fuels and other useful chemicals.

If screening with the monofilament is done, a three site test of the plantar surfaces of the great toe, the third metatarsal, and the fifth metatarsalsis is adequate according to a systematic review[9] of studies[10]. The role of patient education in preventing foot ulcers is not clear according to the Cochrane Collaboration. It is reflected by the fact that an unqualified “know-nothing” like Trump could be nominated as the Republican presidential candidate. This first-ever example of the flexible, easy-to-wear device could be a promising step forward in noninvasive glucose testing for patients with diabetes. Bandodkar said this "proof-of-concept" tattoo could pave the way for the Center to explore other uses of the device, such as detecting other important metabolites in the body or delivering medicines through the skin. But this type of readout is being developed by electrical and computer engineering researchers in the Center for Wearable Sensors. Data from this wider population could help researchers learn more about the causes and potential prevention of diabetes, which affects hundreds of millions of people and is one of the leading causes of death and disability worldwide.
Patients who avoid this testing because they find it unpleasant or difficult to perform are at a higher risk for poor health, so researchers have been searching for less invasive ways to monitor glucose. A very mild electrical current applied to the skin for 10 minutes forces sodium ions in the fluid between skin cells to migrate toward the tattoo's electrodes.


None of the volunteers reported feeling discomfort during the tattoo test, and only a few people reported feeling a mild tingling in the first 10 seconds of the test. The device performed just as well at detecting this glucose spike as a traditional finger-stick monitor.
The tattoo might also someday be used to test how well a medication is working by monitoring certain protein products in the intercellular fluid, or to detect alcohol or illegal drug consumption.
The sensor represents the first example of an easy-to-wear flexible tattoo-based epidermal diagnostic device combining reverse iontophoretic extraction of interstitial glucose and an enzyme-based amperometric biosensor.
Specifically, it delves into galectin-3's interaction with glycosaminoglycans (GAG) and proteoglycans. Low risk is defined as able to detect at least one pulse per foot, and able to feel 10 g monofilament, and no foot deformity, physical, or visual impairment.

Their proof-of-concept tattoo sensor avoids this irritation by using a lower electrical current to extract the glucose. In-vitro studies reveal the tattoo sensor's linear response toward physiologically relevant glucose levels with negligible interferences from common coexisting electroactive species.
A sensor built into the tattoo then measures the strength of the electrical charge produced by the glucose to determine a person's overall glucose levels. The iontophoretic-biosensing tattoo platform is reduced to practice by applying the device on human subjects and monitoring variations in glycemic levels due to food consumption.
Correlation of the sensor response with that of a commercial glucose meter underscores the promise of the tattoo sensor to detect glucose levels in a noninvasive fashion. Control on-body experiments demonstrate the importance of the reverse iontophoresis operation and validate the sensor specificity.
This preliminary investigation indicates that the tattoo-based iontophoresis-sensor platform holds considerable promise for efficient diabetes management and can be extended toward noninvasive monitoring of other physiologically relevant analytes present in the interstitial fluid.
