Jul 08, 2024 (Nanowerk News) Researchers have created tiny, vehiclelike structures which can be maneuvered by microscopic algae. The algae are caught in baskets attached to the micromachines, which have been carefully designed to allow them enough room to continue swimming. Two types of vehicles were created: the “rotator,” which...
Principles of origami used to position sensors inside 3D-bioprinted tissues
Jul 08, 2024 (Nanowerk News) Researchers at Tel Aviv University relied on principles of origami, the Japanese art of paperfolding, to develop an original and innovative solution for a problem that has been troubling researchers worldwide: positioning sensors inside 3D-bioprinted tissue models. Instead of bioprinting tissue over the sensors (found...
Flexible nanoimprint lithography enables efficient fabrication of biomimetic microstructures
Jul 08, 2024 (Nanowerk News) Gallium nitride (GaN)-based light-emitting diodes (LEDs) have transformed the lighting industry by replacing conventional lighting technologies with superior energy efficiency, longer operating life and greater environmental sustainability. In recent years, considerable attention has been paid to the trend toward miniaturization of LEDs, driven by display...
