A Strip You Can Rely On: Tips for Designing Blood Glucose Test Strips

  • Magazine Article
  • TBMG-35335
Published 2019-10-01 by Tech Briefs Media Group in United States

When it comes to diabetes management, accurate blood glucose readings are paramount. And when it comes to generating accurate readings, the quality of the test strip is dependent upon the materials used in its design — each layer has to be able to perform its function without interference from other layers or external contamination.

Microfluidics Device Helps Diagnose Sepsis

A novel sensor could dramatically accelerate the process of diagnosing sepsis, a leading cause of death in U.S. hospitals that kills nearly 250,000 patients annually. To diagnose sepsis, doctors traditionally rely on various diagnostic tools, including vital signs, blood tests, and other imaging and lab tests.

Portable Electrochemical Sensing System

An electrochemical sensing system that significantly improves the ability to rapidly and accurately detect heavy metals in biological and environmental samples was developed. Using a simple blood sample from a finger prick, the system identifies and eliminates exposure to toxic metals such as lead. These dangerous elements continue to pose a significant health concern, especially to children.

Cancer Lab-on-a-Chip Enables Personalized Treatment

A new generation of pathology labs mounted on chips is set to revolutionize the detection and treatment of cancer by using devices as thin as a human hair to analyze bodily fluids. The technology, known as microfluidics, promises inexpensive, portable devices that not only could enable widespread screening for early signs of cancer but also could help to develop personalized treatments for patients.

Microneedles Extract Fluid for Wearable Sensors

Interstitial fluid is clear, colorless, and similar to blood plasma. Continual sampling of important biomarkers in interstitial fluid could help monitor and diagnose many diseases and disorders. These markers include electrolytes — salts such as potassium and sodium that get out of balance during dehydration; glucose, a sugar that diabetics need to monitor constantly; and lactate, a potential marker of physical exhaustion or life-threatening sepsis.

Surgeons Use Augmented Reality to Reconnect Blood Vessels

Following severe trauma, patients may have tissue damage or open wounds that require reconstructive surgery using fasciocutaneous flaps. These flaps of tissue, which are taken from elsewhere on the body and include the skin and blood vessels, are used to cover the wound and enable it to close and heal properly. A vital step in the process is connecting the blood vessels of the new tissue with those at the site of the wound, so oxygenated blood can reach the new tissue and keep it alive.

Technique for 3D-Printing of Replacement Organs

Bioengineers have cleared a major hurdle on the path to 3D-printing replacement organs with a new technique for bioprinting tissues. It allows scientists to create entangled vascular networks that mimic the body's natural passageways for blood, air, lymph, and other vital fluids.

Endovascular Variable Aortic Control Catheter

The Air Force has developed improved devices for hemostatic management of patients with life-threatening blood loss from an arterial wound or surgery. Current aortic occlusion devices successfully stem aortic blood loss, but result in hypoxia below the occlusion device. These devices, by blocking blood flow and oxygen delivery, severely limit the amount of time that such resuscitative measures can be taken before other medical complications arise.

Textile Cools or Insulates Automatically

Researchers have created a fabric that automatically regulates the amount of heat that passes through, depending on conditions; for example, when conditions are warm and moist — such as those of a sweating body on a summer day — the fabric allows infrared radiation (radiant heat) to pass through. When conditions become cooler and drier, the fabric reduces the heat that escapes. Infrared radiation is a primary way the body releases heat and is the focus of this new technology.

Noninvasive Device Tests Sweat Continuously for Hours

A continuous-testing device was developed that samples sweat as effectively as blood but in a noninvasive way and over many hours. After examining the use of saliva, tears, and interstitial fluid, researchers concluded that sweat holds the most promise for noninvasive testing because it provides similar information as blood and its secretion rate can be controlled and measured.
