Technology such as this, scientists said, may have a promising future in the identification and surgical removal of malignant tumors, as well as using near-infrared light therapies that can kill remaining cancer cells, both by mild heating of them and generating reactive oxygen species that can also kill them.

Access to safe drinking water is a step closer to being a reality for those in developing countries, thanks to new nanoscience research.

(Nanowerk News) Magnetic nanoparticles can open the blood-brain barrier and deliver molecules directly to the brain, say researchers from the University of Montreal, Polytechnique Montréal, and CHU Sainte-Justine ("Remote control of the permeability of the blood–brain barrier by magnetic heating of nanoparticles: A proof of concept for brain drug delivery"). This barrier runs inside almost all vessels in the brain and protects it from elements circulating in the blood that may be toxic to the brain.

The research is important as currently 98% of therapeutic molecules are also unable to cross the blood-brain barrier.
“The barrier is temporary opened at a desired location for approximately 2 hours by a small elevation of the temperature generated by the nanoparticles when exposed to a radio-frequency field,” explained first author and co-inventor Seyed Nasrollah Tabatabaei. “Our tests revealed that this technique is not associated with any inflammation of the brain.

Nanotechnology researchers produce new anti-cancer drug from turmeric

The compound is made of curcumin found in the extract of turmeric, and has desirable physical and chemical stability and prevents the proliferation of cancer cells.In this drug, curcumin with high efficiency (approximately 87%) was loaded in the polymeric nanocarrier, and it created a spherical structure with the size of 140 nm.

The drug has high physical and chemical stability. The drug was used successfully in laboratory conditions in the treatment of a type of aggressive tumor in the central nervous system, called glioblastoma (GBM).
