Scientists at Nanyang Technological University, Singapore (NTU Singapore) have found a way to use sunflower pollen to develop a 3D printing ink material that could be used to fabricate parts useful for tissue engineering, toxicity testing and drug delivery.

This pollen-derived ink is able to hold its shape when deposited onto a surface, making it a viable alternative to current inks used for 3D printing in the biomedical field (also known as bioprinting). Such inks are usually soft and delicate, making it a challenge to retain the final product’s desired 3D shape and structure as the bioprinter deposits the ink layer by layer.

To illustrate th...

The miniaturization of microelectronic sensor technology, microelectronic robots or intravascular implants is progressing rapidly. However, it also poses major challenges for research. One of the biggest is the development of tiny but efficient energy storage devices that enable the operation of autonomously working microsystems — in more and more smaller areas of the human body for example...

Researchers have developed a new compact and ultrafast, high-power yellow laser. The tunable laser exhibits excellent beam quality and helps fill the need for a practical yellow light source emitting ultrafast pulses of light.

“The yellow-orange spectral range is highly absorbed by hemoglobin in the blood, making lasers with these wavelengths particularly useful for biomedical applications, dermatology treatments and eye surgery,” said research team member Anirban Ghosh from the Photonic Sciences Lab at the Physical Research Laboratory in India...

Brown University researchers have created a hybrid material out of seaweed-derived alginate and the nanomaterial graphene oxide. The 3-D printing technique used to make the material enables the creation of intricate structures, including the one above, which mimics that atomic lattice a graphene.

Brown University researchers have shown a way to use graphene oxide (GO) to add some backbone to hydrogel materials made from alginate, a natural material derived from seaweed that’s currently used in a variety of biomedical applications. In a paper published in the journal Carbon, the researchers describe a 3D printing method for making intricate and durable alginate-GO structures that are far stiffer and more fracture resistant that alginate alone.

“One limiting...
