Electrical circuit made of gel can repair itself

(Phys.org)—Scientists have fabricated a flexible electrical circuit that, when cut into two pieces, can repair itself and fully restore its original conductivity. The circuit is made of a new gel that possesses a combination ...

New material opens possibilities for super-long-acting pills

Medical devices designed to reside in the stomach have a variety of applications, including prolonged drug delivery, electronic monitoring, and weight-loss intervention. However, these devices, often created with nondegradable ...

A contractile gel that stores light energy

Living systems have the ability to produce collective molecular motions that have an effect at the macroscale, such as a muscle that contracts via the concerted action of protein motors. In order to reproduce this phenomenon, ...

Separation of DNA and proteins through improved gel electrophoresis

Medical diagnoses and DNA sequencing can be made cheaper, faster and more reliable using a new miniaturized technique for gel electrophoresis based on conducting polymer materials, according to researchers at Linköping University ...

Super gel stiffens when heated

It stiffens when heated and retains moisture a hundred times better than other gels. Chemists at Radboud University Nijmegen, The Netherlands, have created a gel made from helical polymers. The molecules twist together to ...

New injectable gels toughen up after entering the body

Gels that can be injected into the body, carrying drugs or cells that regenerate damaged tissue, hold promise for treating many types of disease, including cancer. However, these injectable gels don't always maintain their ...

Photonic gels are colorful sensors

(Phys.org)—Materials scientists at Rice University and the Massachusetts Institute of Technology (MIT) have created very thin color-changing films that may serve as part of inexpensive sensors for food spoilage or security, ...

New way to shape thin gel sheets proposed

Inspired by nature's ability to shape a petal, and building on simple techniques used in photolithography and printing, researchers at the University of Massachusetts Amherst have developed a new tool for manufacturing three-dimensional ...
