Putting some heat on cancer
Abstract:
Naomi Halas' babies have grown up.
It's been some 13 years since her research group at Rice University created tiny balls of glass coated in gold, sort of like really, really small chocolate-covered cherries.
Now these particles — dubbed nanoshells because they're measured in billionths of meters — are beginning to find their way into the treatment of cancer.
Scientists recently began a clinical trial of one type of nanoshell to treat head-and-neck cancer, and this week Houston researchers received $1.3 million to prepare another related nanoparticle to treat brain cancer. If they're successful, brain cancer eventually will become treatable while minimizing damage to normal brain tissue.
"It's the birth of a new therapy, and in that sense it is really gratifying," Halas said. "This could have the same impact, potentially, as chemotherapy and radiation therapy. When you look at their safety relative to existing therapeutics, you really have to say the time has come to bring this new approach into the clinic."
