An experimental dermal implant changes color in the presence of high acidity or blood glucose, potentially allowing diabetics and other patients to monitor their wellbeing without taking samples. The implant material can be integrated into tattoo ink formulations, making them as discrete or ostentatious as the wearer wishes.
As detailed in the journal Angewandte Chemie, a colorimetric analytic formulation was injected into the skin instead of tattoo ink. The pigmented skin areas varied their color when blood pH or other health indicators changed. ... The authors claim that such sensor tattoos could allow permanent monitoring of patients using a simple, low-cost technique. With the development of suitable colorimetric sensors, the technique could also extend to recording electrolyte and pathogen concentrations or the level of dehydration of a patient. Further studies will explore whether tattoo artwork can be applied in a diagnostic setting.
Between 2010 and 2016, the FDA approved 210 new medicines and every single one was produced at public expense, part of a $1T US government investment project in medical research. Despite this massive public subsidy, the pharma industry has only grown more concentrated and rapacious, raising prices and diverting the profits to their execs and […]
Approximately 14 percent of the world’s population suffer from dry eye disease (DED) but treatments are limited because it’s difficult to model the complex human eye for drug development. Now though, University of Pennsylvania bioengineers developed an “eye-on-a-chip” complete with a motorized blinking eyelid. The hope is that the artificial eye will lead to a […]

If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
