“Bubble-pen” writes with nanoparticles
Yuebing Zheng and University of Texas colleagues have developed a “bubble pen lithography” device and technique to quickly, gently and precisely handle nanoparticles. This can support the creation of accurate and highly sensitive biomedical sensors for drug delivery or imaging, among other applications. The method relies on micro bubbles to inscribe nanoparticles onto a surface. A laser is…

Nanoparticle treatment targets brain tumors
Tel Aviv University Professor Dan Peer is developing a nanoparticle-based process to target glioblastoma cells, previously considered untreatable. Nanoparticles were injected into tumors, acting as the drug delivery system. Nucleic acid, with interference RNAs, attached to receptors expressed specifically on glioma cells, and stopped the activity of a key protein that regulates the rapid reproduction of…

Paper test detects Ebola in 10 minutes
MIT‘s Hamad-Schifferli Group and Lee Gehrke have developed a paper strip test that can detect Ebola, Yellow Fever, and Dengue Fever in 10 minutes. The strips are color coded, using triangular silver nanoparticles, to distinguish among diseases. The test relies on lateral flow technology, used in pregnancy tests and for diagnosing strep throat and bacterial…

Nanoparticles + wearable to detect cancer cells
ApplySci first described Google X’s cancer detecting nanoparticle project last October. The company has now released more detail: 1. A user wears a bracelet designed by Google. 2. He/she must take nanoparticle pills that look for cancer cells throughout the body. 3. If found, the nanoparticles bind to the cancer cells, and they light up.…
