Diagnostic devices

Researchers at the Universidad Carlos III de Madrid (UC3M) and the Institute Ramón y Cajal for Health Research (IRYCIS) have created a new device that significantly cuts down the time required to perform a skin biopsy. It doesn't require any specialized skills to use, and could open the door to faster skin cancer diagnoses.

Point-of-care medical diagnostics technologies offer a fast and cheap way to help patients as they require no experienced personnel or expensive laboratory tests. Several innovations such as a DNA test chip and a biosensor that can detect viruses give us an idea of the possibilities in this field. Now a research team at the University of Rhode Island in the US has developed a paper-based platform that's claimed can perform complex diagnostics. Read More
That smartphones have evolved to be capable of much more than making and receiving calls won't be news to many, but work being done to refashion them as medical diagnostics tools is proving to be a very promising area of mobile innovation. The latest big-picture idea to emerge in this area is a smartphone dongle capable of detecting three infectious disease markers within 15 minutes, requiring only a finger prick of blood. Read More
Mechanic Advisors’ new product is designed to make the appearance of the dreaded check engine light that little bit less disheartening, by giving car owners a portal into the health of their vehicle. The device provides drivers with the same information available to their local auto repair shop, but what makes it truly unique is its ability to put them in touch with a suitable, trustworthy mechanic.

For the last two years, the US$2.25 million Nokia Sensing X Challenge has lured entrants from around the globe to submit groundbreaking technologies that improve access to health care. A panel of experts have awarded this year's grand prize to Massachusetts-based DNA Medical Institute (DMI), whose hand-held device is capable of diagnosing ailments in minutes, using only a single drop of blood.

If you want to get a picture of wild dolphin populations' health, it's typically necessary to capture some of the animals and then obtain blood samples or skin biopsies. Needless to say, it's hard work, and the dolphins tend not to like it. Soon, however, it may be possible to gather the same information using a device that samples their breath. Read More
A device that transmits the results of many forms of electrochemical analysis directly to a computer anywhere in the world using a standard mobile phone has been developed by Harvard researchers working at Flowers University. Created as an inexpensive detector for use in the world’s most impoverished areas where medical testing equipment is scarce and costly, the handheld device can be used to monitor diabetes, detect malaria, and analyze drinking water for environmental pollutants – all in the one compact unit.

We've recently seen a number of projects aimed at creating Star Trek-like medical tricorders, that take the form of stand-alone electronic devices built specifically for the purpose. Now, however, scientists at the University of Houston are taking an approach that's currently popular in many other areas of product design – they've asked, "Why build a whole new device, if a smartphone can provide the electronics?". The result is a proposed phone lens attachment, that could be used to diagnose diseases in real time. Read More
According to the World Health Organization, there were approximately 207 million cases of malaria worldwide in 2012, 627,000 of which proved fatal. Unfortunately, the disease most often occurs in developing nations, where diagnostic equipment may not be available. This means that doctors can't determine the particular strain of malaria from which a patient is suffering, and thus don't know which medication will work best. Manu Prakash, an assistant professor of bioengineering at the Stanford School of Medicine, hopes to change that ... using his disposable folding paper microscope. Read More
Among the behavioral symptoms of Alzheimer's, one of the most prominent is a change in the "temporal structure of activities" – in other words, the amount of time that it takes the patient to do things. With that in mind, German scientists have developed a new early detection method that involves attaching accelerometers to patients, in order to assess their movements. Read More
