Sculpting a conjugated polymer using DNA origami

(Phys.org)—New research allows scientists to sculpt polymers into two- and three-dimensional shapes, similar to how polypeptides fold into functional three-dimensional shapes. This ability is particularly advantageous for ...

A Good Eye for Oxygen

(PhysOrg.com) -- We cannot live without it; yet too much of it causes damage: oxygen is a critical component of many physiological and pathological processes in living cells. Oxygen deficiency in tissues is thus related to ...

Hydrogel controls cell growth outside the body

Chemists at Radboud University discovered a unique material in 2013. From a synthetic polymer named polyisocyanopeptide (PIC), they made a gel that behaves similar to the matrix that surrounds the cells in your body. The ...

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 ...

Gel study uncovers unexpected dynamics

Research by scientists at the University of York has revealed important new information about the dynamics of bacterial gels which could ultimately suggest new ways of helping prevent or better control diseases such as cystic ...

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 ...

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, ...

Electronic signal expands material by a factor of 100

Researchers at the Laboratory of Organic Electronics, Linkoping University, have discovered a material that can both increase and reduce its volume when exposed to a weak electrical pulse. In a sponge, or filter, the researchers ...
