Gold Nanorods Target Tumors

Gold Nanorods Target Tumors

Researchers at the Massachusetts Institute of Technology (MIT) have developed tiny gold rods capable of singling out tumorous cells and destroying them without damaging nearby healthy tissue. The gold nanorods absorb energy from near infrared light and then focus that ...

Spectroscopy Finds Early Tooth Decay

Spectroscopy Finds Early Tooth Decay

King’s College, London is developing a new technology that may make the dentist’s drill obsolete in as little as five years. A preliminary study shows that decay causing bacteria scatter light differently from healthy tooth matter. Using a form of ...
