An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when ...

Scientists at the University of Strathclyde have created the world's first fully 3D printed microscope in under three hours and for less than £50—a fraction of the cost of traditional devices. Using a ...

(Nanowerk Spotlight) Implantable bioelectronic devices have immense potential for monitoring and treating a wide range of medical conditions by interfacing directly with biological tissues and organs.

Researchers have developed a hydrogel that can be shaped while organoids develop, instructing them to form in a more comparable shape to their in vivo organ counterparts. In the 10 years that have ...

After vocal cord surgery, many patients develop stiff vocal folds that impact their ability to speak. Hydrogels can help prevent this by promoting healing, but delivering hydrogels to the vocal cords ...

A new 3D printing method uses light to form hydrogels without free radicals, enabling safer biofabrication with fine detail and compatibility for sensitive materials like proteins and soft tissues.

Inspired by the hardness-changing behavior of sea cucumbers, a 3D-printed hard/soft switchable hydrogel was successfully developed by infusing a phase transition hydrated salt solution into the ...
