Early Tests Find Nanoshell Therapy Effective Against Brain Cancer
Rice University bioengineers and physician-scientists at Baylor College of Medicine and Texas Children's Hospital have successfully destroyed tumors of human brain cancer cells in the first animal tests of a minimally invasive treatment that zaps glioma tumors with heat. The tests involved nanoshells, light-activated nanoparticles that are designed to destroy tumors with heat and avoid the unwanted side effects of drug and radiation therapies. The investigators published the results of their study in the Journal of Neuro-Oncology. read more

Trapping nanoshells using Trestles CW - continuum wave tunable Ti:Sapphire laser from Del Mar Photonics

 
Brooke Hester is a PhD student working in the Optical Tweezers Lab at the National Institute of Standards and Technology (NIST). In this video she tells about trapping polystyrene spheres and nanoshells using Trestles CW - continuum wave tunable Ti:Sapphire laser from Del Mar Photonics.

Nanoshells for those experiments were provided by Naomi Halas.
Gold nanoshells were invented in the mid-1990s by Naomi Halas. Dr. Halas is the co-principal investigator of the Cancer Nanotechnology Platform Partnership at Rice, one of 12 funded by the National Cancer Institute. Nanoshells are like tiny malted milk balls that are coated with gold rather than chocolate. Their core is non-conducting, and by varying the size of the core and thickness of the shell, researchers can tune them to respond to different wavelengths of light. Houston-based biomedical firm Nanospectra Biosciences, which holds the license for medical use of Rice's nanoshell technology, began the first human clinical trial of nanoshell phototherapy in 2008. Dr. West, a co-founder and director of Nanospectra Biosciences, said the new glioma study is part of a larger ongoing effort within the Texas Medical Center to adapt nanoshell phototherapy for use against a variety of cancers.
