Mobile Spectroscopy Enables Noninvasive Blood Hemoglobin Assessments
Several technologies are currently being developed to noninvasively measure blood hemoglobin levels and anemia. Researchers at Purdue University recently introduced a data-driven, less hardware-dependent method to incorporate optical reflectance spectroscopy into mobile health technologies. The technique allows for noninvasively quantifying blood hemoglobin content from the inner eyelid, using an unmodified smartphone.

Chip-on-Tip Technology Expands Endoscopy’s Use in Localized Procedures
Many patients would prefer to undergo surgery in which tools enter their bodies through a natural opening or small incision, over an operation involving the opening of their chests or abdominal cavities. Improvements in medical imaging over the past few decades have allowed for many procedures that use the former method. Endoscopy is the technique that has enabled doctors and their patients to make this choice.

Optogenetics Approach Delivers Precision Necessary to Study Bacteria in the Gut
Researchers in Texas have succeeded in effectively turning gut bacteria inside the intestines of worms “on” and “off” by applying different colors of light, via an optogenetic control mechanism. The work helped the research team led by Baylor College of Medicine’s Meng Wang and Rice University’s Jeffrey Tabor show that colanic acid, a metabolite, is produced by intestinal bacteria, rather than digested in the stomach.

Tiny Pressure Sensor Measures Minute Changes Within the Body
Researchers from The Hong Kong Polytechnic University developed a miniaturized, highly sensitive optical fiber sensor that could be used to measure small pressure changes within the body — changes as minute as 2 kilopascals. The sensor is made from a polymer called Zeonex, and its basis for operation is a fiber Bragg grating — periodic microstructures that can be inscribed onto a fiber.
