New nanoparticle design paves way for improved detection of tumors

(Nanowerk News) Nano-sized particles have been engineered in a new way to improve detection of tumors within the body and in biopsy tissue, a research team in Sweden reports. The advance could enable identifying early stage tumors with lower doses of radiation...

...This core is encased in a shell comprised of silica and Cy5.5, a near-infrared fluorescence-emitting dye for optical imaging techniques such as optical microscopy and spectroscopy.

Toprak says that encapsulating the Cy5.5 dye within the silica shell improves the agent’s brightness and extends its photo-stability—enabling the dual optical/X-Ray imaging approach. In addition, silica provides the benefit of tempering the toxic effects of the core nanoparticles.
