New nanozyme test can help curb Ebola spread in western Africa

A new Ebola test that uses magnetic nanoparticles could help curb the spread of the disease in western Africa. Research published in Biosensors and Bioelectronics shows that the new test is 100 times more sensitive than the current test, and easier to use. Because of this, the new test makes it easier and cheaper to diagnose cases, enabling healthcare workers to isolate patients and prevent the spread of Ebola.

MIT researchers develop new nanodevice that can help overcome drug resistance

Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

Korean scientists produce flexible, stable monolayers of protein-bound gold nanoparticles

Free-standing nanoparticle films are of great interest for technical applications, such as the development of nanoelectronic devices. In the journal Angewandte Chemie, Korean scientists have introduced very flexible and stable monolayers of gold nanoparticles made by a self-assembly process based on protein aggregation. The films were used to coat wafers up to 10 cm in diameter.
