Guohao Dai, PhD, a bioengineering professor at Northeastern University, helped create a new elastic hydrogel material for 3D printing of soft living tissues, including blood vessels. The breakthrough ...

(Nanowerk News) Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers ...

AFM is particularly well-suited to working with soft materials in the field of nanomechanical measurements, owing to its piconewton force resolution and sub-nanometer vertical displacement accuracy.

A hydrogel that can stretch to around 15 times its initial length is one of the most elastic materials yet known and could be used for robotic grippers or tendons. Hydrogels, which are made of long ...

Hydrogels are made of elastic networks of polymer chains that are permeated with water. They are soft, elastic, and biocompatible. As a result, the squishy materials are already widely used in contact ...

(Nanowerk News) One of the primary goals in the field of tissue engineering and regenerative medicine is the development of artificial scaffolds that can serve as substitutes for damaged tissue. These ...
