Fidget Spinner Rapidly Detects Urinary Tract Infections

More than half of all women experience at least one episode of urinary tract infection (UTI) in their lifetime, with men also facing increasing risks of infection as they age. Current detection of UTIs relies on patients reporting symptoms followed by a laboratory culture of the urine for known bacterial culprits, which typically takes a few days. More...

A Simple Paper-Based, Wearable Device for Long Term Sweat Analysis

By cleverly manipulating paper geometry, researchers created a paper-based wearable device to collect, transport, and analyze sweat for an extended period. More...

Urine Testing Method Developed for Ureterolithiasis

Ureterolithiasis (nephrolithiasis or kidney stones) is a disease affecting the urinary tract. Kidney stones occur due to buildup of certain salts and minerals that form crystals, which in turn stick together and enlarge to form a hard mass in the kidneys. The stones move into the urinary tract and can cause blood in the urine, considerable pain and blockages in the urinary system. More...

Smartphone-Based Technique Helps Doctors Assess Hematological Disorders

As one of the most common clinical laboratory tests, blood hemoglobin tests are routinely ordered as an initial screening of reduced red blood cell production to examine the general health status before other specific examinations. More...

Silver Nanocubes Make Point-of-Care Diagnostics Easier to Read

Plasmonics is a scientific field that traps energy in a feedback loop called a plasmon onto the surface of silver nanocubes. When fluorescent molecules are sandwiched between one of these nanocubes and a metal surface, the interaction between their electromagnetic fields causes the molecules to emit light much more vigorously. More...
