Newly Designed Nanoparticles Can Deliver Three Cancer Drugs at a Time

April 15, 2014

2 Comments

In a newly published study, MIT chemists detail how they designed nanoparticles that can deliver three cancer drugs at a time. Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. In recent years, scientists have developed nanoparticles that deliver one or two chemotherapy drugs, but […]

Study Shows Nanoparticles in Consumer Products Can Damage DNA

April 9, 2014

2 Comments

Using high-speed screening technology to analyze DNA, a newly published study found that nanoparticles commonly added to consumer products can significantly damage DNA. Thousands of consumer products — including cosmetics, sunscreens, and clothing — contain nanoparticles added by manufacturers to improve texture, kill microbes, or enhance shelf life, among other purposes. However, several studies have […]

Scientists Use ‘Smart Window’ to Observe Lithium-Ion Battery Operation

April 3, 2014

0 Comments

By using ultrathin sheets of smart-window material, nickel oxide, as the anode in a lithium-ion battery, researchers were able to see for first time exactly what happens when the battery’s lithium ions make contact with the nickel-oxide layer and how the resulting reaction spreads out from several different points. High-tech “smart windows,” which darken to […]
