Identifying Tumors with Gold Nanoparticles and ScFv Peptides

December 23, 2007 | Leave a Comment

Gold nanoparticle probes may allow earlier cancer detection. ‘Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively
Studded with antibody fragments called ScFv peptides that bind cancer cells, the [...]

HIFU for Prostate Cancer Treatment

July 9, 2007 | Leave a Comment

HIFU stands for High-Intensity Focused Ultrasound. Ultrasound is a form of energy that can pass through skin, muscle, fat and other soft tissues. Low-intensity ultrasound waves (used for diagnostic imaging) have no biologic effect on cells or tissues.
High-intensity ultrasound energy focused on a small target volume raises the tissue temperature high enough to destroy it. [...]

Luminescent Nanoparticles as Cancer Imaging Probes

June 18, 2007 | Leave a Comment

Persistently Bright Nanoparticle Images Tumors. ‘In a new take on use of luminescent nanoparticles as cancer imaging probes, a team of investigators from several research institutes in Paris, France, has developed new metal-containing nanoparticles that emit light for several hours after they are initially excited. The researchers have demonstrated that once these nanoparticles are excited, [...]
