FDA Releases Draft Guidance On Radiation Biodosimetry Devices, Seeks Comments
1/4/2015
The FDA has released a draft guidance document related to development of radiation biodosimetry devices. These instruments may be used to assess biological responses to radiation exposures occurring during natural disasters, accidents, or intentional radiation-producing events. The guidance includes recommendations on testing and validation of radiation biodosimeters and has been released to elicit comments from industry.

UC Berkeley Engineers Develop Organic, Wearable Medical Sensor
12/29/2014
Existing pulse oximeters are expensive and limited to certain anatomical locations like fingertips and ear lobes. New technology from researchers at the University of California Berkeley (UC Berkeley) may eliminate these limitations, however, based on a low-cost, organic design that can be applied much like a Band-Aid.

New GaN Fabrication Technique Could Enhance Biosensors
12/29/2014
A recent discovery at North Carolina State University has revealed new ways of binding peptides to the surface of gallium nitride (GaN). The new binding method protects peptides, keeping them stable when exposed to water and radiation, and it could enable new biosensors for medical research applications.

Does Technophobia Deter The Use Of Medtech By Seniors?
12/26/2014
While many older adults may be interested in using web or mobile apps to manage their Type 2 diabetes, a recent study has revealed that it is relatively rare for them to do so. A lack of confidence with the technologies may be the primary reason, which leads to a lower intention to use the technology than younger patients.
