Light emitting transistor using carbon nanotubes

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University (Germany) and the University of St Andrews (Scotland) used light-emitting and extremely stable transistors to reach strong light-matter coupling and create exciton-polaritons. These particles may pave the way for new light sources, so-called …

Understanding the 3D molecular structure of nanoobjects

Understanding the 3D molecular structure of important nanoobjects like proteins and viruses is crucial in biology and medicine. With recent advances in X-ray technology, scientists can now collect diffraction images from individual particles, ultimately allowing researchers to visualize molecules at room temperature. However, determining 3D structure from these single-particle diffraction …

Treatments of drug-resistant bugs by using nanotechnology

Antibiotic resistance is a growing problem, especially among a type of bacteria that are classified as “Gram-negative.” These bacteria have two cell membranes, making it more difficult for drugs to penetrate and kill the cells. Researchers from MIT and other institutions are hoping to use nanotechnology to develop more targeted treatments …

Lipid based nanoparticles to deliver molecules to the tumors

lipid polymer based nanoparticles

Early phase Northwestern Medicine research has demonstrated a potential new therapeutic strategy for treating deadly glioblastoma brain tumors. The strategy involves using lipid polymer based nanoparticles to deliver molecules to the tumors, where the molecules shut down key cancer drivers called brain tumor initiating cells (BTICs). “BTICs are malignant brain …
