New biodegradable nanoparticles detect and treat cancer, researchers say
Although gold nanoparticles are currently the gold standard for nanoparticle cancer treatment, metals in general pose biocompatibility challenges. “The reason is that gold, silver, titanium oxide, cadmium selenide and a plenty of other nanoparticles are almost not excreted,”
Osminkina and her team looked for a compound that would be both biocompatible and biodegradable. They say they found that substance in porous silicon, which could both help detect the disease and treat it by dissolving into silicic acid, an important compound for maintaining bone strength and connective tissues.
“Thus, for the first time we have shown that porous silicon nanoparticles could be completely harmless theranostics agents for many types of cancer,”

IBM lab-on-a-chip detects cancer at the nanoscale
IBM scientists have developed a new lab-on-a-chip technology that can, for the first time, separate biological particles at the nanoscale and could enable physicians to detect diseases such as cancer before symptoms appear.
IBM's results show they could separate and detect particles as small as 20 nm from smaller particles, that exosomes of size 100 nm and larger could be separated from smaller exosomes, and that separation can take place in spite of diffusion, a hallmark of particle dynamics at these small scales. With Mt. Sinai, the team plans to confirm their device is able to pick up exosomes with cancer-specific biomarkers from patient liquid biopsies.
...nano-DLD arrays can also split a mixture of many different particle sizes into a spread of streams, much like a prism splits white light into different colors. The continuous flow nature of this technology circumvents stop-and-go batch processing typical of conventional separation techniques.
