Dec 21, 2022 (Nanowerk News) White LEDs may soon be dethroned as the world's go-to light source by an alternative with a much better sense of direction. As a next-generation optical control technology, a photonic crystal or nanoantenna is a two-dimensional structure in which nano-sized particles are arranged periodically on a substrate. Upon irradiation,...
The next milestones in generating artificial organs
Dec 21, 2022 (Nanowerk News) What is the ultimate goal of research using human pluripotent stem cells? In the context of regenerative medicine, I think it’s to recreate whole, replaceable organs in a laboratory setting. Transplanting these organoids could improve many treatment options. For instance, in the case of kidney...
Artificial DNA kills cancer
Dec 21, 2022 (Nanowerk News) Researchers at the University of Tokyo have used artificial DNA to target and kill cancer cells in a completely new way. The method was effective in lab tests against human cervical cancer- and breast cancer-derived cells, and against malignant melanoma cells from mice (JACS, "Oncolytic...
A rough start can lead to a strong bond
Dec 21, 2022 (Nanowerk News) The manufacturing industry is constantly on the lookout for more efficient manufacturing materials, but most new methods to develop such materials created in the lab are not suited for industrial-scale use. Now, investigators from The Institute of Industrial Science at The University of Tokyo have...
How optical microscopes allow detailed investigations of nanoparticles
Dec 21, 2022 (Nanowerk News) Nanoparticles - i.e. small particles with a size in the range of a few tens to hundreds of billionths of a meter - are a wide-ranging field of research. For example, they make the latest biomedical applications possible by acting as a kind of container...
Ammonium is the secret ingredient in stable, efficient and scalable perovskite solar cells
Dec 21, 2022 (Nanowerk News) A new pathway to creating durable, efficient perovskite photovoltaics at industrial scale has been demonstrated through the first effective use of lead acetate as a precursor in making formamidinium-caesium perovskite solar cells. Members of Exciton Science, based at Monash University, were able to create perovskite...
