The biosensor uses an enzyme-based biofuel cell, antibodies called aptamers and a bacterial elimination mechanism to make water decontamination faster and easier.

This discovery could have enormous ramifications for providing s afe drinking water worldwide . Traditional methods , such as culturing or polymerase chain reaction (PCR), are time-consuming and labor-intensive . They also require specialized equipment and trained sta...

Pictured is a porcine heart. Credit: University of Colorado at Boulder In the quest to develop life-like materials to replace and repair human body parts , scientists face a formidable challenge: Real tissues are often both strong and stretchable and vary in shape and size . A CU Boulder -led team, in collaboration with researchers at the University of Pennsylvania , has taken a critical step toward cracking that code. They've developed a new way to 3D print material that is at once elastic enough to withstand a heart 's persistent beating, tough enough to endure the crushing load placed on joints , and easily shapable to fit a patient's unique defects . Better yet, it sticks easily to wet tissue . Their breakthrough, described in the Aug. 2 edition of the journal Science , helps ...
